Application of Paper Covered Copper(Aluminum) Wire:

· Our Paper Covered Aluminum/ Copper Wire uses two layers or several layers as the insulation layer.

· The wrapping direction of paper is same. And every layer paper twines conductors continually and compactly without wrinkles.

· Uses for oil-immersed transformers, reactors and other windings.
