Products Specifications:

●Product introduction: This product is made of oxygen-free copper rod or electric round aluminum rod after being extruded or drawn by a certain size of mold, and then wrapped around 2-3 layers of polyester film or + electrician on copper and aluminum conductor. The non-woven fabric is used as the winding wire of the insulating layer. The product has good withstand voltage and the temperature resistance grade is 130°C of Class B. It is mainly used for winding of transformers, air core reactors and other similar electrical equipment. The company uses advanced online eddy current testing equipment to make product quality more perfect.
