The Varnish Wire manufacturing process adopts spraying one or more uniform paint films conforming to materials on the wires. At present, there are many kinds of varnish wire in the market, and the difference in the properties of different varnish wire is mainly reflected in the coating on the surface.
At present, the varnish wire technology should ensure that the paint films lost before various paint solutions are coated, and the mechanical and electrical plating CP wire, as well as the cold resistance and chemical resistance of the varnish wire, meet the technical index requirements specified by the corresponding varnish wire scale.
It is not easy to produce varnish wire that meets both standard requirements and customer requirements. It is affected by raw material quality, process parameters, production equipment environment and other factors.
Therefore, the quality characteristics of varnish wire are different from those of enameled copper wires, but they all have four major properties: mechanical properties, chemical properties, electrical properties and thermal properties.
