Product overview
This product is suitable for insulating support of overhead lines, and also has the protective function of preventing overhead insulated wires from breaking due to lightning strikes, porcelain insulators blowing up, and reducing lightning tripping. The principle is: when the demand overvoltage exceeds a certain value of insulation blockage, a flashover discharge is caused between the arc striking rod and the steel leg of the demand prevention pillar, forming a short-circuit channel, and the subsequent power frequency arc burns in the discharge gap. to protect the wires from burns. This product also has the function of threading and energizing when applied to insulated wires. The installation and construction are extremely convenient and reliable. Do not peel off the insulation layer to avoid water intrusion and corrosion of the wire core, and it also greatly reduces the labor intensity of the operator. Since the pillar insulator and arc-proof fittings are combined into one (equal potential), they are not affected by the load side of the ring network power supply (away from the power supply side), making the line simple and beautiful and greatly reducing the cost.
