The voltage level of medium-voltage cables is 3kV and above to 35KV, collectively referred to as medium-voltage cables. The main use is in the power sector for power transmission and voltage conversion. Generally used for remote power transmission and substation voltage level conversion.
As we all know, there are many classifications of cables, the simplest classification method is to distinguish between high voltage and low voltage, so how to distinguish low voltage cables from high voltage cables?
The voltage level of medium-voltage cables is 3kV and above to 35KV, collectively referred to as medium-voltage cables. The main use is in the power sector for power transmission and voltage conversion. Generally used for remote power transmission and substation voltage level conversion. Our commonly used voltage level is below 220KV. The remote transmission voltage level is ultra-high voltage. The power department appoints specialized electric workers for construction and maintenance. Many people don't know much about high voltage cables in this area.
Electrical equipment with a withstand voltage of 450V/750V or less is widely used and classified into various categories. Fixed laying generally adopts industrial plastic insulated cables. Move rubber-sheathed low-voltage insulated cables. The building installation is mainly used for laying the main power circuit, each main branch circuit and branch circuit. There are also flat elevator cables specially designed for elevator installations.
