Ground wire suspended glass insulator manufacturer

Overview:

The earth wire insulator is composed of two parts: the insulator itself 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 adjusted, gap discharge occurs, the ground wire is connected to the tower, and various protective functions are activated.

Ground wire insulators can be divided into suspended and tension types based on installation form and electrode structure, with mechanical and electrical failure load levels of 70kN and 100kN respectively.

The ground wire insulator upper and lower electrodes are pre-assembled before shipment, and the discharge gap has been adjusted and securely fastened according to design specifications, eliminating the need for on-site assembly.
