Applications Of Enameled Wire

Enameled wire is a copper or aluminium wire coated with a very thin layer of insulation. The wire itself is most often fully annealed, electrolytically refined copper. There is a big variety of enameled wire types. The different types are described in different standards, such as IEC 60 317, NEMA MW 1000 or JIS C 3202, which sometimes still use different test methods. Different types of enameled wire are important to its applications.

Enameled wire plays an important role in our daily life and industrial electronics. It can be used in many different fields. For example, enameled wire is used in the construction of transformers, motors, generators, headphones, loudspeaker coils, hard drive head positioners, electromagnets, and other devices.

In electric motors. Magnet wire has its unique applications taking advantage of its power to create extremely powerful magnetic fields. Electric motors convert electrical energy into mechanical motion, which usually needs the help of the interaction of magnetic fields and current-carrying conductors. Moreover, electric motors are found in numerous diverse applications, such as fans, blowers, pumps, machines, household appliances, power tools, and disk drives. Some machines are equipped with enameled wire so that the machines can lift something large and heavy. Not all magnet wire is used to move heavy objects. For example, magnets made from this or otherwise made from copper wire may be used in magnetic resonance imaging (MRI) machines. MRI machines use large, strong magnets to scan the inside of the human body, which allows doctors to see your soft tissues and organs.

In transformers. Enameled wire is used for certain high-frequency transformers. A transformer means a device that transfers electrical energy from one circuit to another through its coils. Transformer windings are normally made from copper but aluminium is a suitable competitor where weight and first cost are decisive factors. Enameled wire is used for the manufacture of transformer in the form of wire for small products and strip for larger equipment. The wire must be strong enough to be wound without breakage for small products. Good ductility is essential for the strip.

Felt Painting Method Is Not Suitable For Enameled Wire

Felt Painting Method Is Not Suitable for Enameled Wire Paint with Excessive Viscosity. The distance between the felt fixture and the oven inlet. Felt painting method is not suitable for enamelled wire lacquers where the solvent volatilizes too quickly or is too viscous. Consider the combined force between the leveling and gravity after painting, the drape and the gravity of the paint liquid during the line travel, the distance between the felt and the paint cylinder (horizontal machine) is 50-80mm, and the distance between the felt and the furnace mouth 200-250mm is appropriate.

Specifications of the felt. When the rough specification is applied, the felt is required to be wide, thick, soft, elastic, and has many capillary holes. The felt is easy to form a relatively large die hole in the painting, and the amount of paint is large, and the paint is fast. When applying fine lines, it is required to be narrow, thin, fine, and small in capillary pores. The felt can be wrapped with cotton cloth or sweatshirt to form a fine and soft surface, so that the amount of paint is small and uniform.

The quality of the felt. Painting requires the use of fine, long-quality wool felts (foreign countries have begun to use all-synthetic fibers with excellent heat resistance and wear resistance instead of wool felt). The fat content is less than 0.5%, the pH is pH=7, flat, and the thickness is uniform.

Requirements for felt splints. The splint must be finely machined, not rusted, and maintain a flat contact surface with the felt, which cannot be bent or deformed. Depending on the diameter of the wire, prepare splints of different weights, and try to control the tightness of the felt by the self-gravity of the splint, and avoid pressing with elastic screws or springs. The method of self-gravity pressing enables the paint layers of the individual wires to be fairly uniform.

Prospects Aluminum Enameled Wire

Xinyu Enameled aluminum wire is a new type of enameled wire with copper clad aluminum material as the inner conductor. Its knot has the advantages of copper and aluminum, so it is not only excellent in electrical conductivity but also light in weight. Aluminum enameled wire has been used in many fields, so it will have good application prospects both now and in the future.

In recent years, the position and role of the enameled wire industry in the development of the national economy has become more and more prominent, but because the price of electrolytic copper continues to rise, it has brought a relatively large impact to the related copper wire raw material production and enameled wire supply manufacturers. Under this background, the appearance and application of copper-clad aluminum enameled wire has been proved to be able to replace pure copper enameled wire by user use, which provides a very large business opportunity and a broad market for the development of China’s enameled wire industry.

The traditional pure copper enameled wire mostly uses pure copper as a raw material, which is not only costly, but also vulnerable to shortage of resources. At present, the copper-clad aluminum enameled wire launched by xinyu-enameledwire can not only replace (or super-effectally replace) pure copper in many fields.

In addition, the production cost can be effectively reduced. The replacement of pure copper by enameled aluminum wire and the substitution of imports will greatly promote the development of the national economy and the improvement of the technical level in related fields and the reduction of manufacturing costs.

A Significant Impact On Enameled Aluminum Wire Tension

The process is completed through the necessary mold and equipment cooperation. The focus of this link is the quality control of the coil end. If the mold design or the production is unreasonable, it is very simple to cause the bending deformation of the coil to be severely deformed, resulting in partial insulation damage of the electromagnetic wire. The most direct result of this problem is the problem of coils.

Insulation wrapping is the most cumbersome part of coil making and the most difficult part to control.

The number of layers of motor wrapping with different extra voltages is different. The selected material is mica tape. The most difficult to control is the fit of mica tape lamination.

The straight line side of the coil is generally a fully active machine package method, which simply ensures that the overlapping shares of the stack are common.

Some factories also have manual wrapping conditions, often resulting in overlapping shares that are not common due to human factors, or thick or thin problems.

The insulated thick coil can not enter the slot, and the insulation is thin and the withstand voltage is not up to the requirement.

The handling of tension during the coil wrapping process of Enameled aluminum wire is very important. This is mainly reflected in the process of dressing the end of the coil. If the loosening of the dressing will result in an air gap between the insulation, it is a great quality hazard. Participated in the viewing scene and saw that the mica used by the operator had a significant phenomenon of falling powder. In the process of coil processing, this phenomenon of powder falling is very bad. The primary component of high pressure and corona resistance in mica tape is mica. The share of mica is reduced, and the direct result is that the coil is unqualified.

Xinyu’s Treatment Method For Yellowing Of Enamelled Copper Wire

In a sense, the Enameled Copper Wire manufacturing industry is a material finishing and assembly industry. First, the amount of materials is huge, the cost of materials in cable products accounts for 80-90% of the total cost of manufacturing; second, the types and varieties of materials used are very high, and the performance requirements are particularly high. For example, copper for conductors requires copper purity. Above 99.95%, some products use oxygen-free high-purity copper; third, the choice of materials will have a decisive impact on the manufacturing process, product performance and service life. Among them, the selection of copper enameled wire is especially important, and if it is slightly inadvertent, it may cause a safety accident. Below, I will sort out the reasons and treatment methods for the yellowing of copper enameled wire.

There are several reasons why enameled wire is yellowed:

1. The temperature of the tin furnace is too high, and the fluidity is large, which leads to excessive pinhole penetration and fast penetration of copper and tin.
2 the tin layer is too thin, copper and tin penetrate quickly
3 too much flux halogen residue, copper surface pickling is not thorough enough
4, the packaging time is too fast, the heat is not scattered, the tin furnace impurities
5. The quality of copper is not enough, too much impurities
6. The temperature level has an effect on the activity of copper atoms, and the hot days are faster than the cold days.

These problems can be solved by the following treatments:

1. Mold hole diameter > line pass +0.02mm (the purpose is very simple, the plating layer is too thin);
2. After the production, put it for about 2 hours and then repack it (purpose: internal heat dissipation);
3. Purchase a good flux, with a good flux concentration, mainly the flux affects the tin plating quality;
4. Pick a better oxygen-free copper wire.

Enameled Wire Pressure Resistance

The automotive industry often requires enameled paint films to be thin but with high pressure resistance, taking the 0.71 m m Q(ZY/XY)-2/200 Enameled wire as an example. The pressure resistance of the enameled wire has a direct relationship with the film thickness. In general, for every 0.001 m of film thickness reduction, the breakdown voltage drops by 100 to 150 V. Therefore, in the case where the paint film is thin, in order to obtain a paint film having a high breakdown voltage, in addition to a reasonable insulation structure, the paint film itself must have good insulation properties. This means that the enameled wire lacquer must have a suitable molecular weight and a uniform molecular weight distribution in order to make the film uniform and free of defects; the enameled wire must also be finely filtered, free of gels and mechanical impurities, and have a reasonable solvent formulation. The enamelled wire lacquer can be cured smoothly without defects.

Enameled wire for sealed motor. Lubrication performance. Sealed motors are mostly produced on high speed winding equipment. The winding speed of the winding machine can be as high as 1400~1600 rpm. The enameled wire must also withstand a certain tension when winding. This requires that the surface of the enameled wire should have good wear resistance and slipperiness to avoid the enameled wire being thinned or crushed during winding and weaving.

In the past, the enamelled wire was commonly used as a surface lubricant. However, since the paraffin is easily precipitated from the refrigerant and causes clogging of the capillary in the refrigeration system, the surface of the enameled wire used for the refrigeration equipment is never allowed to exist in the paraffin-like substance. The solution to this problem is to apply a self-lubricating paint film to the surface of the enameled wire to make a self-lubricating enameled wire.
