Product Description

Product Description

In traditionally designed overhead lines, when subjected to direct lightning strikes or induced lightning, the insulator connections in the line system cause flashovers and burn the wires in a very short period of time. The lightning strike and disconnection of overhead lines have become a major problem in the power system, and the emergence of lightning protection hardware has effectively solved this problem.
The fitting is installed on the overhead wire near the line insulator. When the lightning overvoltage exceeds a certain value, a flashover will be caused between the piercing electrode arc-striking arm of the lightning protection fitting and the grounding electrode, forming a short-circuit channel and a continuous power frequency arc. Move it to the arc arm of the wire clip and burn it to release the overvoltage energy to protect the wire and insulator from being burned.

Product features and Conditions of Use

1. Lightning protection arc clamp is a product with a new structure, which is mainly composed of insulation shield, wire clamp seat, puncture pressure block, compression nut arc ball and grounding plate and other details.
2. Lightning protection fittings, the bottom of the lightning protection wire clamp seat is the arc ball with spherical structure. When a lightning strike occurs, there is discharge between the arc ball and the ground plate, so that the continuous power frequency arc moves to the arc ball metal ball and burns. thus play a protective role.
3. Lightning protection fittings, lightning protection arc clip insulation shields are made of organic composite materials, which have good insulation performance, anti-aging performance and flame retardant performance. Assembling it outside the wire clip seat can play a role of insulation protection . The insulating shield is made of organic composite material, which has good insulation performance, anti-aging performance and flame retardant performance. It can be assembled outside the wire clamp to play a role of insulation protection.

1. The wire clamp groove of lightning protection pillar insulator should be installed on the cross arm parallel to the conductor, and the steel foot nut should be secured, which is equivalent to the traditional installation method of insulator, and the arc leading rod should be directed towards the far side of the cross arm (the furthest distance from the cross arm); The arc starting rod should be oriented in one direction, preferably towards the load side;
2. There are two methods of perforation and clamping: (1) Tightening method of the torque nut: insert the insulated wire into the slot as parallel as possible, first tighten the torque nut by hand, and then use a socket wrench to alternately and evenly tighten until the torque The top of the nut comes off. (2) According to the cross section of the wire and the weather temperature, set the torque wrench value to 20-35Nm, and use the torque wrench to tighten the two pressure nuts alternately and symmetrically. The root is enough, and then tighten the backup nut to prevent the pressure nut from loosening;
3. The non-piercing method of wire clipping is: strip off a section of insulated wire of about 65-80mm, wrap it with aluminum clad tape and embed it on the insulator wire clipping hardware. Tighten the compression nut with a wrench to drive the compression block to compress the wire, so as to assemble the insulating sheath to the outside of the compression metal fixture. (For details, please refer to the product installation manual)

1. Ambient temperature of -40 degrees to +50 degrees c
2. Altitude not exceeding 2000m
3. Power frequency is 50~60Hz
4. The maximum wind speed of no more than 35m/s
5. Seismic intensity of 8 degree and below
