Application
Tension clamps can be used to secure power lines. During the power transmission process, power lines need to pass through multiple support towers or poles. Tension-resistant wire clamps can clamp power lines and fix them on support towers or telephone poles to prevent the lines from loosening or falling off. This can ensure the stable operation of the line and avoid failures caused by loosening of the line.
Tensile clamps also protect power lines. During the power transmission process, lines need to withstand the influence of various external environments, such as wind, rain, vibration, etc. Tension-resistant cable clamps can reduce these effects to a certain extent and protect the lines from external interference. When encountering strong winds, the tension clamp can increase the tension of the line and prevent the line from being blown off by the wind.
The tension clamp also has the function of withstanding tension. During the power transmission process, power lines need to withstand a certain amount of tension. The tension clamp can maintain appropriate tension on the line by adjusting the tightness of the clamp. This can ensure the normal operation of the line and avoid failures caused by too much or too little tension.
