Features and Application of enamel coated magnet wire

The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification. The different classes are defined by NEMA, Underwriters Laboratories (UL), and IEC standards.

Kapton insulated aluminium wires are suitable for both HV and UHV applications at temperatures ranging from -269 to 200¡ãC with maximum bakeout temperature of 260¡ãC.
Kapton insulated aluminum wire is designed for use in high & ultra-high vacuum applications. Kapton has high mechanical strength, excellent electrical insulation properties, and low outgassing rates making it ideal for use as an in-vacuum insulator. These wires can be utilized in temperature ranges from 4K to 260¡ãC.

Glass-fiber covered aluminum magnet wire used to have weak coating strength (abrasion resistance, shock resistance, and flexibility). However, that disadvantage has been significantly improved recently by refining material selection and manufacturing methods. The demand for glass-fiber covered aluminum magnet wire is increasing as the wires have excellent uniformity and electrical properties under high temperatures and humidity.

According to the characteristics and uses of insulation, winding wires can be divided into four categories: enameled wires, wrapped wires, special winding wires, and inorganic composite winding wires.

Composite enameled wire is an ideal wrapping wire for large-scale low-voltage and high-current electrical appliances such as power oil-immersed, dry-type, special transformers, electric welding machines, reactor rectifiers, electromagnetic separators, etc., with excellent electrical performance and stability.

Enameled wire is a main type of winding wire. It is made of a metal conductor as a conductive inner core and coated with a polymer insulating layer. It is mainly composed of these two parts; it is the conversion of electromagnetic energy into mechanical energy, heat energy, sound energy, light energy or machinery Functional materials that convert energies such as heat, heat, chemistry, sound and light into electromagnetic energy.

1. What factors affect the softness of the enameled wire and the elongation?

The softness and elongation are good to reflect the quality of the copper quality and the enameled annealing process, and they have a big relationship for the quality of the winding.

2. What is the effect of the thickness of the paint film?

The first tasty or coated is too thick to affect aging performance. The furnace temperature control has a greater impact on aging performance.If the evaporation zone is too sharp, it has a sparp and porront on the paint film, which is poor in these places. The heat of it is high, affecting the thermal aging performance.

3. EffectWhat are the reasons for the bucket breakdown voltage?

Oxe film circle. Overseas impurities in the paint film. Curing. The thickness of the paint film

4. What are the factors affecting the thermal shock??

Influence of the kitcase process. The effect of copper wire. Influence of paint

Nomex covering corresponds to class H insulation is mainly used in the construction of condensers and capacitors. Main application of it is in shielding of cables in high temp. environments (200¡ãC) such as dry type transformers, military and aerospace cables. Nomex covered conductors are more effective in condition where temperature resistance and dielectric strength requirements are high.
Application of Nomex Paper Covered Aluminum wire :
Mobile Transformer,Traction Transfomers,Pole-mounted distribution transformers,Power substantions,rectifiers,oil-immersed transfomer coil winding.

Enameled wire is the most widely used electromagnetic wire in the production of low-voltage products. A key performance requirement of this electromagnetic wire is the continuity of the paint film, which is to check the number of pinholes in the paint film under a certain length. When checking the number of pinholes, use a professional paint film continuity tester. The fewer the number of pinholes, the better the paint film integrity of the magnet wire.

Silver plated copper wire is manufacture with the combination of silver and copper and Silver Plated Copper Electrical Wire is manufactured using grade copper and silver; the industrial standards are always kept into the consideration.

Principle: Water molecule (HHO) decomposes water into oxygen and hydrogen through electrolysis. Hydrogen is combustible. Oxygen supports combustion. These two gases are ignited to form a hydrogen-oxygen flame. In layman’s terms, “water turns into fire”

Aromatic polyimide enameled wire has good heat resistance, softening breakdown resistance, radiation resistance, severe cold resistance and chemical resistance. Among them, many test indicators such as unidirectional scratching, breakdown voltage, and thermal softening are far Far better than ordinary enameled wire.
