Ground wire suspended porcelain insulator manufacturer

Overview:

The earth wire insulator consists of two parts: the insulator itself and the protective gap. The protective gap is formed by electrodes that are secured to the insulator with bolts.

Ground wire insulators are used to support the ground wire in high-voltage overhead transmission lines. When the line operates normally, the ground wire is insulated from the tower, reducing transmission energy loss and enabling ground wire carrier communication. When the ground wire voltage reaches the set value, arc discharges occur, connecting the ground wire with the tower, and providing various protective functions.

Ground wire insulators are categorized into suspended and tension types based on 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 the upper and lower electrodes, and the discharge gap is adjusted and securely fastened according to the design specifications, eliminating the need for on-site assembly.
