Lightning-proof composite insulator is a new type of combined structure arc-proof insulator, which is mainly composed of an insulating shield, a compression nut, a pressure block seat, a moving pressure block, a metal cap, a composite insulator, an arc starting rod, an insulating sleeve and The lower metal foot is composed of an arc starting rod and an upper metal cap. When a lightning strike occurs, the arc starting rod and the lower metal foot are discharged, so that the continuous power frequency arc moves to the arc starting rod and burns, thereby protecting Insulated wires are not damaged.
The mobile pressure block and the pressure block seat are assembled into a whole by a dovetail method, so that when the wire moves due to thermal expansion and contraction, the mobile pressure block moves with it, thereby avoiding the wire from being scratched by the wire clip.
Composite insulators have better insulation performance than PS-15 and other electrical porcelain insulators, and its creepage distance is large, which improves the anti-pollution level of the insulator and can meet the anti-pollution requirements of the majority of users for the insulator.
The insulating shield is made of organic composite material, which has good insulation performance, anti-aging performance and flame retardant performance. It can be used for insulation protection when assembled on the outside of the upper metal cap.
This product has a puncture type thorn structure, easy to install and construct, without stripping the insulation layer of the insulator wire, to avoid water ingress and corrosion of the core, which can greatly reduce the labor intensity of the operator.
Unique structure to prevent birds from causing short-circuit damage to overhead conductors.
Can withstand about 5 times of power frequency high current arc burning.
