Description

Technical Field

[0001] The utility model relates to the technical field of power cables, in particular to a high-protection damage monitoring power cable. Background Art

[0002] A cable is a rope-like cable made of several or several groups of wires twisted together. Each group of wires is insulated from each other and are often twisted around a central wire. The entire outside is covered with a highly insulating covering. The cable has the characteristics of being powered inside and insulated outside. At the same time, the cable can transmit electricity or information from one place to another. When monitoring power lines, cables are often used to connect power lines and monitoring equipment, so that the power status of the power lines can be connected to the monitoring equipment, ensuring that the monitoring equipment can continuously and stably monitor the power lines.

[0003] The inventors discovered in their daily work that in the process of using power cables to connect monitoring equipment and power lines, most of the existing monitoring cables on the market are conventional cables. During use, due to the complexity of the environment, some cables will come into contact with the surface of hard objects such as brackets. Moreover, because the cables are in a suspended state, when the cables are affected by special weather such as external wind, the cables themselves will shake, causing friction between the contact parts and hard objects, and wearing out the insulation layer on the surface of the cable, which can easily lead to serious damage to the insulation layer of the cable. Utility Model Content

By installing the damping plates inside the first arc cover and the second arc cover, the resistance between the first arc cover, the second arc cover and the insulating layer can be increased after the first arc cover and the second arc cover are installed, so as to improve the stability of the first arc cover and the second arc cover in the installed state.

[0011] Preferably, the positioning sleeve is nested with the surface of the first arc cover, and the positioning sleeve is nested with the surface of the second arc cover. By installing the positioning sleeve on the insulating layer, the installation positions of the first arc cover and the second arc cover can be preliminarily restricted after the position of the positioning sleeve is restricted.
