Product Description
Flat enamelled copper conductor is the standard solution for winding designs that want high fill factor and thin insulation together. The rectangular section stacks almost gap-free in the winding window; the enamel coating stays a few hundred microns thick. The result is higher current capacity and better heat conduction in the same volume.
The coating is formed by applying a polyamide-imide top layer over a polyesterimide base layer. The base layer provides dielectric strength and flexibility, the top layer resistance to friction, chemicals and sudden temperature rises. This structure allows a Class 200 (N) continuous operating temperature.
Produced to the general requirements of IEC 60317-0-2 and verified by the IEC 60851 series test methods: build increase, breakdown voltage, continuity (pinhole), flexibility and softening temperature are monitored on every batch. The NEMA MW 1000 equivalent is certified for North American projects.
Applications
Power and distribution transformers, large electric motors, generator windings, reactors, wind turbine generators.
