The wire tension clamp is a hardware used to fix and anchor the conductor or ground wire in the power transmission line. It bears mechanical tension and maintains electrical connection to ensure reliable current transmission. With the development of wire tension clamps, more and more power systems choose to use pre-twisted wire tension clamp. Why is this?
According to statistics from the Southern Power Grid, the construction efficiency increased by 60% and the labor cost decreased by 75% after using Pre-twisted wire tension clamp. In the Zhangbei Flexible Direct Current Project, the pre-twisted wire tension clamp operated for 3 years without failure under ±500kV/3000A conditions. The above data all show the necessity of using pre-twisted wire tension clamp.
Pre-twisted wire tension clamp are a kind of power hardware specially used for overhead lines. It connects the conductor, ground wire, and tension wire to the tension tower by cooperating with the heart-shaped tension ring. Its structure is simple and reliable, and it can withstand the full tension of the conductor, ground wire, and tension wire, ensuring the stable operation of the line in various environments. Preformado wire guy grip uses high-strength materials, and its holding force can meet the national standard requirements. It is higher than the traditional wire tension clamp. The selected materials are exactly the same as the stranded wire, which plays a further protective role.
If preformado wire guy grip is not used, the power transmission system may be in danger. The traditional bolt-type wire clamp is easy to loosen under long-term vibration. A 330kV line once caused the wire to fall to the ground due to the bolt falling off, causing a 72-hour power outage. There is stress concentration in the compression type wire clamp. A wind farm in Xinjiang had a wire strand break at the wire clamp, and the repair cost exceeded 2 million yuan. Preformado wire guy grip solves the problems of stress concentration, complex installation and frequent maintenance of traditional products through structural innovation and material upgrades, highlighting the important value of pre-twisted technology.
