Product Overview
Cable paper covered wire is made of oxygen free copper rod or electrician round aluminum rod by a certain specification mold extrusion or drawing annealing treatment of wire, and then in copper (aluminum) conductor wrapped two or more layers of insulation paper (including telephone paper, cable paper, high voltage cable paper, turn to turn insulation paper, etc.) winding wire, suitable for oil-immersed transformer coil and other similar electrical winding wire. Electrical bare copper (aluminum) wire produced by extrusion process is the ideal material for the production of cable paper covered wire.
Paper-covered copper flat wire has some unique characteristics compared with other types of wire and cable. First of all, because it uses paper-wrapped insulation materials, it has high insulation performance and can effectively prevent the leakage and interference of current. Secondly, the flat shape of the paper-covered copper flat wire makes it more convenient during installation and wiring, saving space and reducing clutter. In addition, the paper-covered copper flat wire has excellent electrical conductivity, can transmit larger current and higher voltage, and is suitable for a variety of high-load electrical equipment. Finally, the paper-covered copper flat wire has good wear resistance and aging resistance, and can maintain stable electrical properties in long-term use.
