[0002] Cable is a component for transmitting electric energy or signals. It is an electrical component that can be found everywhere in real life. The different usage locations of various cables allow cables to be installed at high altitudes, underground and on the seabed to supply power to different equipment. In real life, in places with more complex geographical environments such as hills and mountains, cables are still installed at high altitudes to form overhead lines for easy transmission of electric energy.

[0003] In the prior art, the two ends of the overhead line are usually fixed between two power racks. After the high-altitude cable is fixed between the two power racks, in order to maintain sufficient tension between the two power racks and avoid the cable swaying between the two power racks in windy weather, the cable needs to be stretched between the two power racks.
