medium voltage power cable are suitable for medium voltage power transmission scenarios and have advantages such as long transmission distance and large transmission capacity. The voltage withstand level of medium voltage cables is usually 0.6/1kV to 26/35kV, suitable for different electrical equipment and occasions.
There are various types of medium voltage cables according to different classification standards. According to the conductor material, medium voltage wire can be divided into copper medium voltage cables and aluminum medium voltage cables; According to the insulation material, it can be divided into polyethylene insulated medium voltage cables, cross-linked polyethylene insulated medium voltage cables, and rubber insulated medium voltage cables; According to the structure, it can be divided into single core medium voltage cables and multi-core medium voltage cables; According to their usage, they can be divided into two types: mv cable for urban power grids, medium voltage power cable for industrial use, medium voltage cables for mining use, and medium voltage cables for petrochemical use.
When choosing medium voltage cables, the following aspects need to be considered:
Cable cross-sectional area: The cross-sectional area of the cable is determined based on the power and current requirements of the electrical equipment to ensure safe transmission of sufficient current.
Materials for cables: Select appropriate conductor materials (copper or aluminum) and insulation materials (polyvinyl chloride, cross-linked polyethylene, etc.) according to the usage scenario and current requirements.
Voltage resistance level of cables: Select the corresponding voltage resistance level according to the voltage requirements of the electrical equipment.
Cable laying method: Choose the appropriate laying method (direct burial, conduit, bridge, etc.) based on the usage scenario and environmental factors.
