EIW 180 Grade polyester imine enamelled copper wire

Enameled wire is an indispensable material in modern society such as vibrant electrical appliances, electronic machines, motors, transformers, relays and even automotive parts. Chalco has various types of enameled wires, including enameled aluminum wire, enameled copper wire, enameled copper clad aluminum wire, high-tension wire, magnetic wire, stranded wire, etc. Chalco's special enameled flat wire is suitable for high-precision coils and has won the trust of the industry.

EIW 180 Grade polyester imine enamelled copper wire

The main component of EIW 180 insulating varnish is polyisocyanate-imide resin, which has good thermal shock resistance, high softening resistance and high breakdown temperature, excellent mechanical strength, good solvent and refrigerant resistance, and is widely used in heat resistance Windings of demanding motors, electrical appliances, meters, power tools, electric dry-type compressors, etc., are vulnerable to hydrolysis under closed conditions.

Characteristics of EIW 180 Grade polyester imine enamelled copper wire:

1.High heat resistance.

2.Excellent chemical resistance.

3.High heat shock.

4.High softening breakdown.

Application:

Oil-immersed transformer, small motor, high-power motor, high-temperature transformer, heat-resistant component
