Compared with wires, the main feature of cables is that it is better insulated. The wire usually consists of one or more flexible wires and is wrapped in a soft shell on the outside. The cable consists of insulated wire and is packed in a strong metal or rubber layer. This makes the cable more suitable for power transmission over long distances and in harsh conditions.
In addition, there are several other types of cables, such as flexible mineral insulated cables (BTLY cables). The cable is mainly made of copper wire, mineral insulation materials and copper materials using inorganic materials. Flexible mineral insulated cable to make up for the traditional rigid, flammable, toxic and other shortcomings.

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.
