Double Glass-fiber Covered Rectangular Copper Wires

The product is independently upgraded and developed by innovative technology, and the quality of insulation structure is more stable. After bending, there is no damage to the insulation layer, which effectively avoids the most vulnerable insulation point damage when the product is transposed. The tensile adhesion is excellent, which can withstand the large inclination angle displacement when the coil is bent, and avoid the tearing of the insulation layer. The electrical performance is stable with high breakdown value. The three-dimensional angle is uniform, which ensures the uniform flow rate of internal water cooling or oil cooling, and has good mechanical performance and sealing performance.With higher mechanical property, overload capacity and resistance to heat and humidity, this product is applicable to the windings of large and medium-sized high-voltage motors and generators, transformers and various electric devices.
