Protect the cable from damage: The protective coating of the cable is located on the outside of the cable insulator, and its main purpose is to protect the inner layer of the cable from mechanical damage and chemical corrosion. This helps to extend the life of the cable and ensure its stable operation under various conditions. By increasing the mechanical strength: By increasing the mechanical strength of the cable, the protective coating can increase the elasticity of the cable. This is necessary to ensure that the cable can withstand external forces during transmission to avoid damage caused by external forces.

Classification and application of cable
The classification of cables and their applications are very extensive, involving many fields, such as electrical systems and information transmission systems. According to the application, cables can be divided into bare wire, insulation, heat insulation, shielding, electrical, controllable, cable, radio frequency, etc. Cables are mainly used in power grids, including overhead wires, wires (buses), power cables, branch cables,

Focus on cable line construction and business concerns
The construction and operation of cable lines is an important part of power supply, and its quality and safety directly affect the reliability of the power supply system. Before cable construction, technical measures in line with the actual operation of the site shall be studied and formulated in detail, and shall not be changed without authorization. In addition, the quality of cable construction is not only related to itself, but also related to its quality. Therefore, in the construction of cable lines, relevant regulations must be strictly observed to ensure the quality of work.

Pay attention to the use of cables
When selecting and using cables, several aspects need to be considered to ensure safety and efficiency. First of all, the selection of appropriate cable products on the basis of use, setting conditions and safety is closely related to various sectors of the national economy. Secondly, when installing the heat pipe and the cable at the same time, it is necessary to maintain a proper distance, at least 50cm cross. In addition, when installing directly, the industrial cable must be at a depth of at least 70cm. When installing the cable console, the semiconductor protection must be removed to avoid damage to the cable insulation.

Prevent mechanical damage: The mechanical damage of the cable is one of the main reasons for its failure. This usually occurs with uneven rearrangement or when building earthwork structures on direct cables. The production, testing and installation of cables must be carried out in strict accordance with national standards to prevent such failures.

Brief difference between cable core and quality?
People with a lot of rods are called multi-core cables. regular multi-channel chipsets: 10, 12, 16, 24, 32, etc. Multi-core cable () -Upgrade of single-core cable. Due to the actual use of three-phase four-wire power supply, three-phase five-phase power supply, the number of multi-loop power supply increased

What is a rigid insulated cable?
Excellent fire resistance is the main feature of insulated cables. Since the cable is composed of inorganic substances (metal copper and magnesium oxide), it will not cause a fire, nor will it burn or ignite. This is a real fireproof cable.
