Product Description

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.

Product Installation Instructions

Installation instructions: This product is installed on the cross arm, and the nut can be tightened. It is equivalent to the traditional insulator installation method. The arc striker is facing the load side. At this time, the outer layer of the wire should be close to the bottom of the wire slot, and the piercing teeth should pierce the wire. The insulating layer is closely connected with the conductive layer inside the wire, an insulating shield is installed outside the wire clamp, and the insulating shield is fixed with a fixing buckle

Product features and application range

With the popularization and application of insulated overhead distribution lines, if the necessary and effective lightning protection measures are not taken, the insulated lines will be broken due to lightning strikes caused by direct lightning strikes and induced lightning, and the insulators will burn out. Our company applies the lightning protection principle of external gap arc ignition to the pin insulator, and adopts the patented puncture type structure and the unique arc ignition device structure (which can be replaced and maintained separately), which is easy to install (no need to peel off the insulating layer), High performance (self-weight pressing contact), simple and beautiful (with silicone rubber insulation cover), not only has the function of pin insulator, but also has the function of lightning strike and disconnection, suitable for the installation of 10 ~ 20kv overhead insulation new lines or old lines The improvement has great promotion value.
