Wire Enamels

Wire Enamels! Insulating Varnishes! Impregnating Resins!

PRIMARY INSULATION

Electrical gadgets, for example, engines, generators, and transformers capacity on the premise of electromagnetic prompting. The rotational or direct development of such electrical turning hardware is created by electromagnetic fields, produced by electrical loops, and their common aversion powers.

We offer you distinctive items from the Primary Insulation for various industrial applications.

Wire Enamels

“Bawa Polymers Wire Enamels cover the complete range of product requirements. Applications vary from fine wires for miniaturized electronic components all the way to heavy-round and rectangular conductors for large motors, in other words from small electrical motors up to big generators and transformers.”

Polyester Wire Enamels
