Difference between enameled wire and paper wire
Enamelled wire is a main kind of winding wire, which is composed of conductor and insulation layer. After annealing and softening, enameled wire is baked by repeated coating.However, it is not easy to produce products that meet both the standard and customer requirements. They are affected by the quality of raw materials, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires are different, but they all have four major performances: mechanical performance, chemical performance, electrical performance and thermal performance.
Paper wrapping wire still occupies a considerable position in the wrapping wire, which is mainly used in the oil-immersed transformer.The oiled paper insulation formed at this time has excellent dielectric properties, low price and long life.Paper is made up of oxygen free copper rod or electrical round aluminum rod through must have specifications of the kneading mould or annealing treatment after drawing wire, again on the copper (aluminum) conductor winding and two or more than two layers of insulation paper (including telephone paper, cable paper, high voltage cable paper, turn-to-turn insulation paper, etc.) of the winding line, used in oil-immersed transformer coil and other similar electric winding thread.
