[0002] The tension clamp is a hardware used to fix the conductor to withstand the conductor tension and hang the conductor on the tension string group or pole tower. Existing tension clamps such as the tension clamp disclosed in the invention patent with publication number CN113241701B and the universal tension clamp disclosed in the invention patent with publication number CN118783332B can fix the cable.

[0003] However, it was found during use that since some of the tension clamps were installed at the seaside and were exposed to sea breeze for a long time, and the sea breeze had high humidity and salinity, the tension clamps were prone to rust, affecting their service life. In addition, since the wind at the seaside is strong, and most of the tension clamps clamp the cables by fastening with bolts, the sea breeze blows the cables, causing them to shake frequently and repeatedly squeeze the tension clamps, which can easily loosen the bolts. In addition, the cables rub against the tension clamps during shaking, which can easily cause cable wear, resulting in poor practicality. Therefore, there is an urgent need for a power line tension clamp to improve the above problems. Summary of the invention
