Generally, the winding methods of Aluminum Magnet Wire https://www.xinyu-enameledwire.com/product/ mainly include all overlapping winding and all gap winding. Usually, the innermost and outer layers are overlapped and wrapped, and the other layers are wrapped with gaps. In the production process of enameled wire, condensation curing of paint and evaporation of solvent are carried out at the same time, and the smell and air pollution brought out by evaporation of a large amount of solvent.

Aluminum magnet wires are composed of a certain number of enameled copper flat wires into two rows with wide surfaces in contact with each other, and the upper and lower surfaces of the two rows of enameled flat wires are transposed along the narrow surfaces in the same direction as required, and then electrical insulating paper and ropes or tapes are used as winding wires for continuous winding.

At present, with the increase of output, people and environmental protection departments are paying more and more attention to it, and it has also become a topic facing enterprises. Therefore, energy conservation and environmental protection have become hot topics in enameled wire industry.

At present, energy conservation and consumption reduction have become the key work of the Chinese government. Under the requirements of the general environment, enameled wire industry should also attach great importance to and solve the problem of high-temperature waste gas pollution.

Enameled Wire https://www.xinyu-enameledwire.com/ is also called winding wire. It is often divided into enameled wire, wound wire, enameled wound wire and random wire according to the material and manufacturing method of the electrical layer. The original enameled wire is an oily enameled wire made of tung oil, etc. It cannot be directly used to manufacture motor coils and windings. When in use, a cotton yarn wrapping layer should be added. Later, the polyvinyl formal enameled wire was invented. Its mechanical properties were greatly increased and it can be directly used in motor windings, which is called enameled wire.

With the development of weak current, self-adhesive enameled wires have appeared again, and coils with better integrity can be obtained without impregnation and baking. However, its mechanical strength is poor, and it can be used in micro and special motors and small motors. In addition, in order to avoid the trouble of paint film before welding, a direct-welding enameled wire has been developed, and its coating film can automatically fall off in a high-temperature tin lining tank, thus making the copper wire easy to weld. The application of enameled wire is becoming more and more extensive, and the requirements are becoming more and more strict.

Enameled wire can be divided into polyester enameled wire, polyester imide enameled wire, polyamide-imide enameled wire, polyimide enameled wire, polyamide-imide enameled wire, corona resistant enameled wire, oily paint, acetal paint, polyurethane enameled wire, etc. according to the paint used. Sometimes it is also classified according to its application, such as self-adhesive enameled wire, cryogen-resistant enameled wire, etc.

Aluminum Magnet Wire https://www.xinyu-enameledwire.com/product/ refers to the magnet wire with aluminum as the core, which is used to make insulated wires for coils or windings in electrical products. Also called winding wire. It is necessary for magnet wire to meet the requirements of various applications and manufacturing processes. The former includes its shape, specification, ability to work at high temperature for a short time and a long time, as well as acceptance of intense oscillation in some occasions and centrifugal force at high speed, resistance to corona and breakdown under high voltage, resistance to chemical corrosion under special atmosphere, etc. The latter includes the requirements of stretching, twisting and abrasion during winding and embedding, swelling and erosion during dipping and drying.

Aluminum magnet wire can be classified according to their basic composition, conductive wire core and electrically insulating layer. Generally, it is divided into aluminum core enameled wire, aluminum core wrapped wire, aluminum core enameled wrapped wire and inorganic insulated wire according to the insulation material and manufacturing method used for the electrical insulation layer.

The aluminum magnet wire is prepared by coating the conductor with corresponding paint solution, evaporating the solvent, curing the paint film, and cooling. The enameled wire can be divided into polyester enameled wire, polyester imide enameled wire, polyamide-imide enameled wire, polyimide enameled wire, polyester imide/polyamide-imide enameled wire, corona resistant enameled wire, oily paint, acetal paint, polyester enameled wire, etc. according to the insulation paint used. Sometimes it is also classified according to the particularity of its use, such as self-adhesive enameled wire, cryogen-resistant enameled wire, etc.

Inorganic insulation wire for aluminum electromagnetic wire: when the heat resistance level exceeds the limit of organic materials, inorganic insulation paint is generally selected for coating. Existing inorganic insulation wires can be further divided into glass film wires, oxide film wires, ceramic wires, etc.

Because the use of aluminum electromagnetic wire is increasingly widespread and the requirements are increasingly strict, composite enameled wires have also been developed. The inner and outer paint films are made of different polymer materials, such as polyesterimide/polyamideimide enameled wire. Therefore, aluminum magnet wires are increasingly used in various related professions, and the industrial position of aluminum magnet wires cannot be replaced.

In the process of winding and embedding the motor coil, the mechanical force acts on the enameled wire, such as tensile force, friction force and bending force during winding. There is friction in the embedding process. There is inter-turn friction caused by vibration during motor operation. If the core wire or paint film of the Copper Winding Wire https://www.xinyu-enameledwire.com/product/ cannot meet the requirements, the above-mentioned mechanical forces will bring different degrees of damage. Therefore, it is important to establish various mechanical performance tests on the basis of simulating the use requirements.

Elongation test:

Elongation rate is established by simulating the winding process of enameled wire. Its purpose is to control the adaptability of wire to winding coil and ensure smooth operation. After the enameled wire is stretched, its adhesion, scratch resistance, elasticity, thermal shock and solvent resistance will all decline to vary degrees.

Rebound angle test:

The softness of copper winding wire is an important index in use. The coil wound on the wire mould, such as enameled wire, will rebound and deform due to poor flexibility, which will directly affect the processing quality and labour productivity of the coil winding.

Flexibility and adhesion:

Flexibility and adhesion tests include winding, stretching, rapid breaking and peeling twisting tests. Enameled wires are subjected to two external forces when winding coils. (1) Tensile force. If the elasticity of the paint film is insufficient, the elongation of the paint film after being stressed cannot keep up with the elongation of the conductor, and the paint film will crack. (2) Bending force: the paint film on the outer edge is elongated after bending, and the paint film on the inner edge is compressed. If the elasticity is not good, the paint film will also crack. Fine lines are easy to be stretched and tested by elongation method. Thick lines are greatly affected by bending and are tested by the winding method.

Scratch resistance:

Pressure or friction force will act on the enameled wire during winding and moulding of coils, the embedding of wires and operation of electrical products. The scratch-resistance of the paint film is expressed by the number of times the paint film resists scratching or the scratch force under the action of external force.

Heat resistance test:

Heat resistance is an important index, which is of great significance to motors and components or windings with severe temperature rise requirements. It directly affects the design and use of electrical equipment. The temperature rise of electrical equipment is limited by enameled wires and other insulating materials used. If enameled wires with high heat resistance and matching materials can be used, good stability can be obtained under the condition of unchanged structure, or the energy-saving effects of reducing external dimensions, weight, non-ferrous metals and other material consumption can be achieved under the condition of keeping power unchanged.

Thermal ageing test:

It takes six months to one year (UL test) to measure the thermal performance of enameled wire by thermal life assessment method. The ageing test lacks application simulation, but it is still significant to control the quality of paint and the baking degree of the paint film in the production process of copper winding wires.

Thermal shock test:

Heat shock resistance test is to study the tolerance of enameled wire film to heat under mechanical stress.

Heat-resistant softening breakdown test:

In the coil, the lower enameled wire is subjected to the pressure caused by the tension of the upper enameled wire. If the enameled wire is heated and softened during the pre-drying or drying process of impregnation or during operation at high temperature, the paint film will gradually be squeezed thin under the pressure, which may result in turn-to-turn short circuit of the coil.

In a sense, the wire and cable manufacturing industry is a material finishing and assembling industry. Among them, the selection of copper wire is especially important, and a little carelessness may cause safety accidents. Today, I would like to share with you some reasons and treatment methods for yellowing of Copper Winding Wire https://www.xinyu-enameledwire.com/product/ .

The yellowing of copper winding wire is usually caused by the following reasons:

1. The high temperature and high fluidity of the tin furnace lead to large pinholes in the coating and rapid penetration of copper and tin.

2. The tin layer is too thin, copper and tin penetrate quickly.

3. The flux has too much halogen residue and the copper surface is not thoroughly pickled.

4. The packaging time is too fast, the heat is not scattered, and the tin furnace contains too many impurities.

5. The quality of copper material is not satisfactory, and there are too many impurities.

6. The temperature has an effect on the activity of copper atoms, yellowing faster when the temperature is high than when the temperature is low.

If the Aluminum Winding Wire https://www.xinyu-enameledwire.com/ is in a high-temperature state for a long time, it will be quite disadvantageous to the equipment and will burn down. If it is serious, it will also cause safety accidents. For this, people need to pay more attention, actively prevent and prevent accidents.

If the aluminum winding wire is overheated, it is very likely that it is caused by the failure to open the forming switch of the protection circuit in time and to automatically lose power. If the whole time lasts for a long time, it will cause bad influence, which needs to be solved in time.

1. In order to avoid overheating of the aluminum winding wire, it is necessary to repair the multi-hydraulic check valve, grind the inner wall again, and replace the aged parts in time, so as to ensure the working sensitivity.A

2. The electromagnetic starting valve needs to be reformed. The main method is to take out the internal spring, which can provide gravity by the gravity of the valve core. This not only effectively reduces the water pressure on the aluminum winding wire but also can prolong the service life of the sealing part.

People must actively avoid overheating of aluminum winding wires, or serious consequences will result.

With the rapid development of social economy, urbanization is also accelerating step by step. There are more and more electrical appliances in the home. From the old type of electrical appliances to the new type of electrical appliances now, it has brought sufficient convenience to our life. So when people use electrical appliances, they can use electricity everywhere. In order to enable electricity to be installed and normally transmitted to various households to maintain the normal use of electrical appliances, Copper Clad Aluminum Winding Wire https://www.xinyu-enameledwire.com/product/enameled-rectangular-copperaluminum-wire/ have certain quality requirements. Next, let's take a look at the inspection of qualified products of copper clad aluminum winding wires.

Inspection of qualified products of copper clad aluminum winding wire:

1. Direct current resistance: The direct current resistance of copper clad aluminum winding wire can reflect the quality of copper core material. Under a certain cross-sectional area, if the direct current resistance is qualified, the copper clad aluminum winding wire is even passed a big hurdle.

2. Insulation resistance: check the insulation performance of the copper clad aluminum winding wire. The insulation resistance is whether the copper clad aluminum winding wire leaks electricity and whether the leakage current increases after reaching a certain temperature under normal operation.

Through the above understanding, we have learned about the quality requirements of copper clad aluminum winding wires, which are used everywhere in our life. This has certain requirements for the quality of electric wires, and the price of copper clad aluminum winding wires is relatively low.

The clad welding of Copper Clad Aluminum Winding Wire(XINYU-ENAMELEDWIRE) http://www.xinyu-enameledwire.com/product/enameled-rectangular-copperaluminum-wire/ adopts advanced manufacturing technology. The high-quality outer surface is concentrically clad between the core wire of aluminum or copper rod wire and the copper layer and core wire with strong metallurgical bonding between atoms. The two different kinds of metal materials are integrated into an indivisible whole, which can be used for drawing and annealing treatment to be single-wire processing. The volume ratio of copper to aluminum is constant when the drawing process is proportional to the diameter.

Due to the skin effect of high-frequency signals, copper clad aluminum winding wires and copper-clad steel wires have the same conductivity as pure copper wires at high frequencies (over 5MHz).

The composite material of the copper clad aluminum winding wire has unique performance: the copper clad aluminum winding wire and the combination characteristics of the density and conductivity of aluminum and copper are small at the same time; And copper-clad steel wire, high-strength copper and steel together. Tin-plated copper-clad steel wire plays a role in solderability and vulcanization resistance of tin. Silver-plated copper-clad steel wire has increased electrical conductivity, thermal conductivity, corrosion resistance and oxidation resistance. Therefore, it has a wide range of applications.

The ECCA wire is a new type of magnet wire that accepts copper-clad aluminum as the inner conductor. Its characteristics are between copper and aluminum, combining the excellent electrical conductivity of copper and the lightweight of aluminum. Below is an introduction to the ECCA wire by ECCA Manufacturer(XINYU-ENAMELEDWIRE) http://www.xinyu-enameledwire.com/ .

Features of the ECCA line:

1. DC resistivity: The DC resistivity of the copper clad aluminum wire is about 1.45 times that of the pure copper wire; at the same time, the weight of the copper clad aluminum wire is about 1/2 of that of the pure copper wire.

2. Good solderability: The copper-clad aluminum wire is coated with a layer of pure copper concentrically, so it has the same brazability as the pure copper wire, and does not have to be specially treated like the aluminum wire; The copper clad aluminum wire has a thick copper layer to ensure that the soldering performance of the product is not affected when the paint is scraped;

3. Lightweight: The copper-clad aluminum wire density is 1 to 2.5 times that of the pure copper wire with the same diameter, which is very effective for the weight of the low coil; the copper clad aluminum wire can replace the copper wire, which can save at least 30% of the cost.

At present, Enameled Copper Clad Aluminum Wire(XINYU-ENAMELEDWIRE) http://www.xinyu-enameledwire.com/product/enameled-copper-clad-aluminum-wire/ are mainly used in low-voltage power cables. Although medium-voltage cables are also involved, the number is very small. Like wires for electrical equipment, the main reason why enameled copper clad aluminum wires are used as conductors in power cables is also due to the rise in copper prices and the fact that enameled copper clad aluminum wires are superior to aluminum-core cables in joint links. Internationally, standards such as UL1581, UL1072 and UL83 in the United States have made corresponding regulations on the performance and wire gauge of enameled copper clad aluminum wire as a power cable conductor, but there are few examples in actual application. Up to now, enameled copper clad aluminum wire has only enterprise standards.

In the past three years, wire and cable with enameled copper clad aluminum wire as a conductor have been widely used. At the same time, many enterprises have entrusted their products to the national wire and cable quality supervision and inspection centre for inspection. As of the end of April 2008, nearly 40 cable enterprises have entrusted the inspection centre to carry out type tests. As far as the inspection situation of enterprises is concerned, the products currently submitted for inspection are mainly concentrated in power cables, and mainly cables under 10 kV, of which 1kV cables account for about 80% of the total number of products submitted for inspection, and 10kV cables account for about 20%.

It is precise because of the above factors that the number of enterprises producing enameled copper clad aluminum wire in China has a trend of increasing year by year. From 2005 to 2006, there were only about 3,500 manufacturing enterprises in the country, to 2007, dozens of enterprises have already entered or are preparing to enter this product field.

Aluminum Magnet Wire(XINYU-ENAMELEDWIRE) http://www.xinyu-enameledwire.com/product/paper-covered-rectangular-copperaluminum-wire/ refers to the magnet wire with aluminum as the core, and the magnet wire is used to manufacture insulated wires of coils or windings in electrical products. Also called winding wire. Magnet wires must meet the requirements of various applications and manufacturing processes. The former includes its shape, specification, ability to work at high temperature for a short time and a long time, as well as withstanding strong vibration in some occasions and centrifugal force at high speed, corona and breakdown resistance under high voltage, chemical corrosion resistance under special atmosphere, etc. The latter includes the requirements of stretching, bending and abrasion during winding and embedding, as well as swelling and erosion during impregnation and drying.

Aluminum magnet wires can be classified according to their basic composition, conductive wire core and electrically insulating layer. Generally, it is divided into aluminum enameled wire, aluminum wrapped wire, aluminum enameled wrapped wire and inorganic insulated wire according to the insulating material and manufacturing method used for the electrically insulating layer.

Enameled wire of aluminum magnet wire: coat the conductor with corresponding paint solution, and then volatilize the solvent, solidify the paint film and cool it. Enameled wires can be divided into polyester enameled wires, polyester-imide enameled wires, polyamide-imide enameled wires, polyimide enameled wires, polyester-imide/polyamide-imide enameled wires, corona-resistant enameled wires, as well as oil paints, acetal paints, polyurethane enameled wires, etc. according to the insulation paint used. Sometimes it is also classified according to the particularity of its application, such as self-adhesive enameled wire, cryogen-resistant enameled wire, etc.

The winding of magnet wire: An Important Variety of Winding Wire. Early use of cotton yarn and silk, known as yarn and silk wrap, was used in electrical machines and appliances. Due to the large insulation thickness and low heat resistance, most of them have been replaced by enameled wires. At present, it is only used as a high-frequency winding wire. In large and medium-sized winding wires, when the heat resistance level is high and the mechanical strength is high, glass wire wrapping wire is also adopted, and appropriate adhesive paint is matched during manufacturing.

Paper winding still occupies a considerable position in winding and is mainly used in oil-immersed transformers. The oil-paper insulation formed at this time has excellent dielectric properties, low price and long service life. In recent years, film winding has developed rapidly, mainly polyester film and polyimide film winding. Recently, there are mica tape coated polyester imine film coated copper flat wire for wind power generation.

Alloy materials belong to the category of metal materials. Compared with pure metal materials, alloy materials combine the characteristics of a variety of metal materials and have better service performance, and can reduce the use of some metal materials to a certain extent and save raw materials. Enameled copper clad aluminum wire has good electrical properties and is relatively widely used nowadays. Then the ECCA Manufacturer(XINYU-ENAMELEDWIRE) http://www.xinyu-enameledwire.com/ will introduce its manufacturing method.

1. Pull the copper clad aluminum wire core 4 to 6 times.

2. paint that pulled wire core 10 to 13 time, and the painting steps are as follows: (1) Paint the wire core; (2) Putting the painted wire core into an annealing furnace for annealing; (3) Putting the annealed wire core into an oven for drying.

3. Take-up. The speed of take-up is required to be 51m/min.

4. Lower wall and package.

In the content of the above article, I introduced some methods of making enameled copper-clad aluminum wire in detail. Do you all know how to make enameled copper-clad aluminum wires now? The enameled copper-clad aluminum wire can be used instead of pure copper, thus saving the consumption of copper resources to a certain extent.

How to remove paint from the Copper Winding Wire(XINYU-ENAMELEDWIRE) http://www.xinyu-enameledwire.com/ is generally divided into the following three methods according to different conditions, equipment and requirements.

1. For ordinary thin wires, tin can be directly applied on a soldering iron at 400 degrees Celsius. For thick wire, we don't recommend the method of baking by fire, which will make the copper winding wire oxidized and affect its properties. Even if it is finished reluctantly in time, some air holes will be found on the surface of the upper tin.

2. We can also apply rosin to the broken ends of copper winding wire and put the cross-section into a soldering iron to melt in. The cross-section has no paint, so tin will be applied quickly. The surrounding of the cross-section will be stripped of paint and tin will be applied without attachment force as the temperature increases. We just need to control the temperature.

3. The third method is to use paint. Professionally qualified paint does not cause any damage or corrosion to the metal. It can quickly make the paint on the surface of copper winding wire, and the removed paint becomes lumpy, without adverse consequences or residues on the surface of copper winding wire. After paint removal, the core wire has excellent weldability and is now processed in batches in many industrial manufacturing sites by this method. Now, it has largely replaced the old method of scraping fire with a knife, and the cost and effect are also greatly improved.
