High Strength Backup Clamp
The Backup Clamp is suitable for aerial line up to 220kV, fixing aluminium wire or steel core aluminium wire on the strain pole.
Description
Description:
1 High strength: The backup clamp can meet the working tension not less than 40%:
2 Corrosion resistance: The material used is the same as the wire base material, so as to ensure good corrosion resistance.
3 Conductivity: The pre-twisted shunt strip used for wires and jumpers has good conductivity with frosted inner layer, so the flow capacity of the wires after connection is not affected. In actual operation, due to the effect of stretching, the electrical conductivity will get better and better. At the same time, the heat dissipation area is increased, which is conducive to the safe operation of the line;
4 Convenient installation: The installation of the safety backup clamp is simple and convenient. No special tools and special professional skills are required; the installation quality is easy to guarantee: no special training is required, and the inspection can be performed with the naked eye, and the appearance is simple and beautiful.
5 Adaptability: Light weight, full of flexibility, and strong resistance to vibration fatigue.
6 Maintenance-free: The force on the pull-up wire per unit area is very small, which has a super protective effect on the wire and ensures the service life of the wire.
Application:
Share the mechanical and electrical performance of the compression strain clamp and increase the overall system safety factor.
Application occasions used for high-voltage transmission lines crossing important facilities (such as electrified railways, expressways), sharing the failure of compression strain clamps, this safety backup clamp can prevent the conductor from falling and cause greater accidents, and win repairs Precious time.
