●Product Name: cable paper covered wire
● Product Introduction: cable paper covered wire is wire used oxygen free copper rod or aluminum wire rod processed by extrusion mould or annealing, and then lapped by 1-2 layers of  insulating paper (telephone paper, cable paper, high tension cable paper, interturn insulating paper), this product is suitable for oil-immersed transformer coil and other similar electric winding. Electrician naked copper (aluminum) conductor with extrusion process is ideal material for fibre glass-covered copper (aluminum) wire.
