Paper covered wire is a type of winding wire which starts from oxygen-free copper rod or round aluminum rods extruded or drew by a certain size of the mold, and then wrapped by a specific insulating material. Xinyu mainly offers Kraft Paper Covered Wire and Nomex Covered Wire at the current stage. Paper covered wire is mainly used for oil-immersed transformers, reactors and other electrical devices winding. Enameled Copper Wire is specialized in producing paper covered wires and other winding wires.

Our implementation of standards and quality requirements are listed as follows:
1. The implementation of standards: GB/T7673.3-2008 (Paper Covered Copper Wire)
2. The quality requirements: the tape should be tight, uniform, smooth wrapped on the conductor. There should be no lack of layer, wrinkles, cracks, and gaps in tapes when overlapped. Thick insulation layer is allowed for Tape joints and insulation adjustment, but the length can not be greater than 500mm.
If any lack of layers, cracks happed in the production process, it will affect the insulation performance of the paper covered wires. And also resulting inwithstand voltage of the part and discharge, then breakdown and explosion will be followed for the transformer. However, if the overall size is too big due to thick insulation thickness. The overall coil size of the transformer will be too large, the outside shell is difficult to fit as well.
As a leading Enameled Wire suppliers, xinyu enameled wire are mainly used as tight coils of insulated wire in motors, speakers, hard disk head actuators, electromagnets, etc.
