Lightning protection insulator
FXG8 series of lightning protection insulator for overhead lines, the overhead insulated wire or bare wire connected to the bar or corner of the metal fittings, which will be elevated wire tension and insulation, and play a lightning protection role.
Product Introduction
This product is suspended in the transmission and distribution lines, the insulator on the right is the low potential, then the insulator between the left and right high and low voltage electrode to form an air gap between the main use to provide lightning flashover channel and arc discharge channel, its action The voltage is lower than the insulator body, and must first operate with the insulator body flash before the action, so that lightning drainage, protection of insulators and wires.
When the overhead insulated transmission and distribution network by direct lightning or induced lightning, the insulator left and right ends of the arc rod to provide the air gap before the insulator flashover before the action of discharge, providing lightning flashover channel, established in the lightning flashover channel Up the arc or single-phase short-circuit current arc root, can only be fixed in the lead-bar provided by the high and low voltage electrode, and not flow string to the insulator body or wire, thus avoiding the insulator group burns, The phenomenon of burning insulated wire.
This product meets the international standards of the line insulator of the technical standards, and insulators to improve the performance of various indicators, as far as possible plug the discharge, in the case of blocked and then to ease the way to mine. Insulators and anti-arc fittings into one, to hang tension transmission line, it can be installed horizontally with respect to the poles, can also be vertical tension hanging on the line bracket, with great economic and practical Sex. The arc rod of this product can provide many times the frequency of the arc ablation, reliable performance, can effectively prevent the insulator due to lightning damage and insulation wire lightning strikes accident occurred.
Among them, the insulator core rod ends of the end of the shape of gold can be connected according to the needs of transmission and distribution lines, and constantly change its shape to facilitate the insulator on the line connection.
