1. Transformer insulating paper Mainly used in high-voltage cables and large oil-immersed transformers, mainly used for wire wrapping
2. insulating paper for power Transformer is one of the factors affecting the power transformer grade. Transformers are graded, with A, B, E, F, H, and C. This is divided according to the operating temperature, the power transformer is Class A, and the maximum operating temperature is 105 degrees, which is the oil-type transformers. Dry change has F grade (epoxy resin) with a maximum operating temperature of 155 degrees. There are also dry-type transformers of class H (maximum operating temperature of 180 degrees) and class C (maximum allowable operating temperature of 220 degrees) made of insulating paper from ZTelec Group in the China E and B are used to make motors. This temperature is determined by the insulating material
