How the insulation material is divided by grade

pe mica tape insulation and temperature are closely related. The higher the temperature, the worse the insulating properties of the insulating material. In order to ensure the insulation strength, each insulating material has an appropriate maximum allowable operating temperature, below this temperature, can be used for a long time safe, more than this temperature will quickly aging. According to the degree of heat resistance, the g10 fiberglass tube is divided into Y, A, E, B, F, H, C and other levels, the heat resistance level corresponding to the following:
 Y-class insulation temperature of 90 ℃
 Class A insulation temperature 105 ℃
 Class E insulation temperature 120 ℃
 Class B insulation temperature 130 ℃
 F-class insulation temperature of 155 ℃
 H-class insulation temperature of 180 ℃
 C-class insulation temperature above 200 ℃
