As an important power transmission tool in power system, low voltage cable has a wide range of applications. This article will introduce the basic knowledge of low voltage cable, including the structure, classification and use of content.

A low-voltage cable is a conductor used to carry low-voltage electrical signals, typically used in residential, commercial, and industrial applications. It consists of a conductor, an insulating layer, a shielding layer and an outer sheath. The conductor is usually made of copper or aluminum, and its purpose is to carry current. The purpose of the insulating layer is to prevent short circuit or leakage of current during transmission, and is generally made of polyethylene and other materials.
According to different uses and characteristics, low-voltage cables can be divided into many types, such as plastic insulated cables, rubber insulated cables, mineral insulated cables, etc. Each type of cable has specific advantages and applicability in different situations.
Low-voltage cables play a vital role in the power system. They can be used for power supply inside buildings, outdoor transmission lines, and connection of electrical equipment. The selection of low-voltage cables should be determined according to specific needs, including transmission distance, carrying current, environmental requirements and other factors.
In general, low-voltage cables play an indispensable role in modern power systems. By understanding its structure, classification and application areas, we can better choose the right low-voltage cable to ensure the safety and stability of power transmission.
