500 kV insulator is mainly used in mortgaged overhead distribution lines, made of special raw materials, and plays an important role in use. When using plastic combination insulators, pay attention to some methods and matters of use, to prevent the aging of insulators, have a certain impact on the equipment, damage the efficacy of the equipment, and cannot play the effect of insulation. Plastic composite insulators for low-voltage overhead distribution lines generally use high-density polyethylene as the main material, plus an anti-aging agent for one extrusion molding, and can be made into various types of low-voltage insulators according to the different uses of insulators.
