0.5mm class 155 Electric Motor Winding Wire Enameled Copper Wire
Polyesterimide/polyamide composite enameled wire, thermal class
180, the product has good thermal shock resistance, high softening
breakdown temperature, excellent mechanical strength, good solvent
resistance and refrigerant resistance, and its weakness is that it
is easy to be damaged under closed conditions. Hydrolyzed, widely
used in windings of motors, electrical appliances, instruments,
power tools, dry-type power transformers, etc. with high heat
resistance requirements.
