LV power cable

A low-voltage power cable is a type of power cable. It is suitable for fixed laying in AC 50Hz, rated voltage 3kv and below transmission and distribution lines for transmission of electric energy.

Category:

Purpose:

Scope of application of low-voltage power cable: buried in the soil or laid indoors, channels, tunnels, small insulation distance between lines, no pole tower, less land occupation, basically does not occupy the space on the ground.

Feature:

The possibility of electric shock is small and safe to use. It is less affected by climatic conditions and surrounding environment, with stable transmission performance and high reliability. The distributed capacitance is large, the maintenance workload is small, and it has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables.

The conductor of the flexible rubber‑sheathed mobile mining cable typically consists of several strands of fine copper wires. The insulation material is an ethylene‑propylene rubber compound, while the sheath material is a flame‑retardant chlorinated polyethylene blend. Different shielding structures and sheath colors are employed depending on the voltage levels. This cable is primarily used for electrical connections in underground mobile mining equipment, for connecting cutting machines and similar devices, for linking underground frequency‑conversion units, as well as for interfacing with mobile frequency converters installed underground, among other applications.
