The role of insulating material

Insulation material is one of the key factors to determine the technical and economic indicators of electrical and electrical appliances. In the electrical equipment, the charged parts are separated from each other. Therefore, the insulating material should first have high insulation resistance and compressive strength and can avoid the occurrence of Leakage, breakdown and other accidents. Second, the heat resistance is better, to avoid long-term overheating and aging deterioration; In addition, there should be good thermal conductivity, resistance to lightning and high mechanical strength and process processing and other characteristics.
An unsaturated polyester glass mat sheet used to isolate conductive parts of different potentials. Its conductivity is about 10-10 West / m below. Different electrical products, according to the needs of insulating materials are often also play energy storage, cooling, cooling, arc, moisture, mildew, anti-corrosion, radiation protection, mechanical support and fixed, protective conductor and so on.
