Fhpq-10/20kv Puncture Type Lightning Pod Insulator

This product is suitable for the insulation support of overhead lines, and has the function of preventing the overhead insulated wires from being broken by lightning strikes, the porcelain insulation being blown up, and reducing tripping due to lightning strikes. The principle is: when the lightning overvoltage exceeds a certain insulation blocking value, it will cause a flashover discharge between the arc rod and the steel foot of the lightning protection column, forming a short-circuit channel, and the subsequent power frequency arc will burn at the discharge gap. to protect the wires from being burned. This product also has puncture and live functions when applied to insulated wires. The installation and construction are very convenient and reliable. There is no need to peel off the insulating layer, so as to avoid water ingress and less corrosion of the wire core. At the same time, the labor intensity of the operator is greatly reduced. Since the pillar insulator and the anti-arc metal parts are combined into one (equipotential), they are not affected by the load side of the ring network power supply (deviation from the power supply side), making the circuit simple and beautiful, and greatly reducing the cost.
