Ground wire type suspended ceramic insulator

Overview:

The earth wire insulator is composed of two parts: the insulator and the protective gap. The protective gap is formed by electrodes fixed on 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, allowing the ground wire to conduct with the tower, thereby 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' upper and lower electrodes are pre-assembled before shipment, and the discharge gap has been adjusted and securely fastened according to the design requirements, eliminating the need for on-site assembly.
