 Why Choose QZ-2/155?

         ·         Excellent balance of thermal performance and cost

         ·         Grade 2 heavy build for enhanced dielectric strength

         ·         Good chemical resistance and moisture protection

         ·         High mechanical strength for high-speed winding

         ·         Widely used in household appliances and industrial motors

         ·         Proven reliability for over 20 years in field applications

 Grade 2 (Heavy Build) Advantage: QZ-2/155 features a double-coated polyester insulation that provides superior dielectric strength compared to Grade 1. This heavy build ensures reliable performance in standard motors, transformers, and coils where cost efficiency and durability are equally important.

Reliable Performance for Everyday Electrical Applications

CHINGCUNG QZ-2/155 polyester enameled copper wire is engineered for applications requiring reliable insulation at operating temperatures up to 175°C. The Grade 2 heavy build provides an additional layer of protection against voltage stress and mechanical abrasion, making it the go-to choice for general-purpose motors, transformers, and solenoids.

Our advanced manufacturing process ensures uniform coating thickness and excellent adhesion. Each batch undergoes rigorous testing including dielectric breakdown, heat shock, scrape resistance, and continuity. With ISO 9001:2015 certified facilities, CHINGCUNG delivers consistent quality for OEMs worldwide.
