Product introduction:
FXG series lightning protection suspension insulators are suitable for overhead lines. They connect overhead insulated wires or bare wires to the fittings of tension poles or corner poles, thereby tightening and insulating the overhead wires and providing lightning protection.
This product is suspended on the transmission and distribution lines. The right end of the insulator is at low potential. At this time, an air gap is formed between the high- and low voltage electrodes at the left and right ends of the insulator. It is mainly used to provide lightning flashover channels and arc discharge channels. Its action The voltage is lower than the insulator body, and it must act before flashover with the insulator body, causing lightning to flow and protecting the insulator and wires.
When the overhead insulated transmission and distribution network is struck by direct lightning or induced lightning, the air gap provided by the arcing rods at the left and right ends of the insulator can discharge before the insulator flashover, providing a lightning flashover channel, and establishing a lightning flashover channel. The arc root of the power frequency arc or single-phase short-circuit current can only be fixed on the high and low voltage electrodes provided by the arc rod and will not flow to the insulator body or wires, thus avoiding burns to the insulator umbrella group and even The burning of insulated wires occurs. This product meets the technical standards of line insulators stipulated in international standards and improves various performance indicators of the insulators to block discharge as much as possible. If the blockage cannot be blocked, it will be protected against lightning by means of diversion. Insulators and arc-proof fittings are combined into one, which can be hung and tightened on transmission and distribution lines. It can be horizontally tightened and installed relative to poles, or vertically tightened and hung on line supports. It is very economical and practical. sex. The arc striking rod of this product can provide multiple power frequency arc ablation with reliable performance, which can effectively prevent insulators from being damaged by lightning strikes and insulated wires from being disconnected by lightning strikes.
Among them, the shape of the end fittings at both ends of the insulator core rod can be continuously changed according to the needs of transmission and distribution line connections to facilitate the connection of the insulator to the line.
