Ground Wire Sway Insulator Manufacturer

Overview:

The ground wire insulator consists of two parts: the insulator itself 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. 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 is adjusted, gap discharge occurs, the ground wire connects with the tower, and various protective functions are activated.

Ground wire insulators can be categorized into suspended and tension types based on installation and electrode structure, with mechanical and electrical failure load ratings 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 required.
