Ground wire suspended glass insulator

Overview:

The ground wire insulator consists of two parts: the insulator itself and the protective gap. The protective gap is formed by electrodes that are 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 set, gap discharge occurs, and the ground wire is connected to the tower, exerting various protective functions.

Ground wire insulators can be categorized into suspension type and tension type 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 requirements, no on-site assembly is needed.
