3M paper insulated copper aluminum wire for transformer winding
3M paper covered aluminium wire feature :
* High dielectric strength/Excellent therm alstability/Wrapped tightly;
* Paper covered Aluminum wire is a special kind of magnet wires. Its conductors is electrical round aluminum rods which squeeze
and draw by the certain size of mold. And its insulations is special material;
* Our 3M paper covered aluminum 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;
Production Details:
