Low Voltage Quadrangle Type Electrical Ceramic Insulator Porcelain Stay Insulator
Product Description
It is used for pole wire or tensioning wire and insulation in power frequency AC or DC overhead power lines. The ambient temperature of the installation site is -40℃ to +40℃, and the altitude is not more than 1000m.
An insulator made of electrical porcelain. Electrical porcelain are baked from quartz, feldspar and clay. The surface of porcelain insulator is usually covered with enamel to improve its mechanical strength, waterproof infiltration and increase the surface smoothness. Among all kinds of insulators, porcelain insulators are the most commonly used.
