Round enameled copper wire grades ПЕТВ-1, ПЕТВ-2


Copper winding wires are designed for winding of electric motors stators, transformers, electromagnetic relay, coils of oscillating circuits of products with maximum thermal and mechanical loads and also for winding of electric machines and devices

Copper winding wires can be used either for mechanical or manual winding.

The wires are manufactured on the modern equipment of the Austrian manufacturer MAG AG using the insulating materials of the French company IVA ESSEX SAS. Packing of the final products is performed on spools K-125/K-250 according to IEC 60264-2  (winding up to 20 kg), placed on the wooden pallets and tied up with polypropylene band.
