Overview:

The ground wire insulator consists of two parts: the insulator and the protective gap. The protective gap is formed by electrodes fixed to the insulator through 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, there is gap discharge, and the ground wire is connected to the tower, performing 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 upper and lower electrodes before shipment, and the discharge gap has been adjusted and securely fastened according to design specifications; no on-site assembly is required.
