Because the high voltage cable clamp is an elongated member, the electric field distribution is not uniform to improve the electric field distribution, and also for the arcing of a high voltage cable clamp of 10 kV or more, a pair of equalizing tests and operation are required to confirm that the High voltage cable clamp has the following Strengths: Strong against pollution. The surface of the high voltage cable clamp is hydrophobic, and the water is granulated on the surface. The high voltage cable clamp has a small diameter, a large creepage distance, a high surface resistance, and a low leakage current, so that the discharge voltage is high. High strength and light weight. Due to the high tensile strength of the rod core, the High voltage cable clamp can be made very light. It can reduce the force of the tower, reduce the installation and maintenance strength, and save a lot of cost. Small size and light weight. Because the High voltage cable clamp is small in size and light in weight, and the umbrella disk is flexible and not easily damaged, it brings great convenience to transportation, installation and maintenance.
For the application of High voltage cable clamp, although its price is higher than porcelain insulator, high voltage cable clamp will be the ideal material from the long-term comprehensive economic benefits. The higher the voltage, the more obvious its economic benefits can be foreseen, followed by the increase of power transmission capacity. The Yamato voltage level is further improved. The high voltage cable clamp is bound to be widely used in power systems.
