Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power transmission, in particular to an ultra-weather-resistant corrosion-resistant cable joint adopting a composite coating. BACKGROUND

[0002] With the rapid development of the communication industry, from the past simple telephone cable to thousands of pairs of cable, coaxial cable, optical cable, data cable, and even combined communication cable. The structure and size of such products are usually small and uniform, and the manufacturing precision is high. Most wire and cable products have the same cross-sectional shape (ignoring manufacturing errors), which is a long strip-shaped product. This is determined by the characteristics of being used as a line or coil in a system or device. Therefore, the structure and composition of the cable product can be analyzed by observing the cross-section. At the same time, the cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. There are power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. The cable joint on the cable is a cable joint connector with another cable joint connector. At the same time, the cable joint is also called a cable head. After the cable is laid, in order to make it a continuous line, each segment of the line must be connected as a whole. These connection points are called cable joints. The cable joint at the middle part of the cable line is called an intermediate joint, and the cable joint at the two ends of the line is called a terminal head. The cable joint is used to lock and fix the incoming and outgoing lines, and plays a role in preventing water, dust and vibration. The main function of the cable joint is to connect the cable line and ensure the continuity of power transmission, and to ensure the safe and reliable operation of the system through sealing and insulation design.

[0003] Since the cable joint usually adopts a crimping connection method, improper operation may cause the joint to loosen. If the crimping is not tight, it is easy to cause excessive resistance at the joint, and long-term operation may also cause the cable joint to heat up. At the same time, most cable joints are exposed to the external environment. If the sealing and protection measures of the cable joint are not strict, water or water vapor is easy to enter, and after being electrified, the conductor will heat up and cause the cable to oxidize and turn black. This not only affects the service life of the cable, but also has safety hazards such as fire and explosion. SUMMARY
