Ground Wire Porcelain Insulator Factory

Overview:

The earth wire insulator is composed of two parts: the insulator and the protective gap. The protective gap is formed by electrodes fixed to the insulator with bolts.

Ground wire insulators are used to support the ground wire in high-voltage overhead transmission lines. During normal operation of the line, the ground wire is insulated from the tower, reducing transmission energy loss and enabling ground wire carrier communication. When the ground wire voltage is set, gap discharge occurs, and the ground wire is connected to the tower, performing various protective functions.

Ground wire insulators can be divided into suspended type and tension type according to the installation form and electrode structure, with mechanical and electrical failure load ratings of 70kN and 100kN respectively.

The ground wire insulators are pre-assembled with upper and lower electrodes, and the discharge gap has been adjusted and secured according to the design specifications, requiring no on-site assembly.
