Hi Voltage Suspension Porcelain String Insulator Overhead Line Power Accessories
Quick Detail
Product advantage
Good insulation, good heat resistance, low price, rich experience in operation, low cost and so on.
Suspension porcelain insulators are made of porcelain, iron caps and steel feet with Portland cement and quartz sand glue. 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 the iron cap and steel feet are all hot-dip galvanized. The contact surface of the iron cap and the steel foot and the adhesive is thinly coated with a buffer layer, and the top of the steel foot has an elastic pad.
Stain-resistant insulators are divided according to their umbrella structure:
