The Electrical Insulation Paper Sheet produced by ZTELEC has good mechanical strength, high electric strength, large tightness, small shrinkage and good flatness. It is widely used in transformers, capacitors, transformers and other equipment. Used as insulation material. The emergence of this material has brought about a new height in China's mechanical industry.
