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;
