The abrasion resistance test of the varnish coating on enameled wire reflects the strength of the varnish's resistance to mechanical scraping.
Thermal Resistance: Includes thermal shock and softening breakdown tests.
The thermal shock of enameled wire is the ability of the wire's enamel coating to withstand heat under mechanical stress.
Factors affecting thermal shock: paint, copper wire, enamel winding process.
Compared to single-coated magnet wire, composite coated magnet wire boasts the following advantages:
1. Can meet special usage requirements, such as refrigerator and air conditioner compressor with frost-resistant wire, which can be achieved through the structure of the composite coating.
2. By combining various insulating layers, its characteristics can be complemented, thereby enhancing and improving its performance to meet usage requirements.
3. Can reduce the cost of certain enameled copper wires, such as polyester imide, polyamide imide composite coated enameled copper wires replacing the single-coated polyamide imide enameled copper wires, which can significantly lower its cost.
