Product advantage
Good insulation, rich experience in operation, good heat resistance, low price, low cost and so on.
Insulators play two fundamental roles in overhead transmission lines, namely supporting the conductors and preventing current from returning to the ground. These two functions must be guaranteed. Insulator should not change due to environmental and electrical load conditions lead to various electrical and mechanical stress and failure. Otherwise, the insulators will not have a significant effect, which will damage the use and operating life of the entire line.
Hanging by the porcelain, porcelain insulator iron cap and steel legs with no less than 525 Portland cement, quartz sand cement gel pack. The contact surface between the iron cap and the steel foot and the adhesive is lightly coated with a buffer layer, and the top of the steel foot is provided with elastic liner. The surface of the porcelain parts is usually painted with white glaze and brown glaze, and other glazes can be painted as needed. The surface of iron cap and steel foot is all hot-dip galvanized.
