Ceramic Line Post Insulator are a type of steel insulator, Line Post Insulator is used for supporting wires and resisting electric current, High Voltage Line Post Insulation consisting of one or more insulating members permanently glued to a metal base, sometimes with a cap,and can be double mounted on a metal base. The head bolt or one or several bolts are steel mounted on the support structure. Porcelain Power Line Insulators are suitable for temperatures between -40° C to +40° C, heights below 1000m(1000m and above can be amend base on GB311.1-1997), frequencies not exceeding 100Hz, voltages above 1000V, and mechanical loads within the rated values of the product.
