Power cables allow the successful transmission of electrical energy from one place to another. These cables provide the channel to transmit high-speed data. The same cables have the ability to power these electrical devices. There are usually three categories in which the transmission of power is been categorized.
- High Voltage Power Transmission
- Medium Voltage Power Transmission
- Low Voltage Power Transmission
Every category has different ranges and different power cable capacity. Low voltage power cable has the tendency to transmit the power to the electrical application ranging from 50V to 1000V for alternating current and 75V to 1500V for direct current.
Low Voltage Power Cables are further categories as follows.
- XLPE Insulated Cables
Cross-linked Polyethylene cables are the one which is massively used in electrical insulation. It is massively used in electrical buildings, radiant heating and cooling systems, water piping and insulation for high tension (high voltage) electrical cables.
- Multiple Core Cables
Number of cores that a single cable has is directly proportional to its voltage capacity. Cable capacity and cable sizing depend on some major parameters. In which the prime condition is cable installation place, cable continuous current, voltage drop, and earth fault loop.
Most of the times the use of multiple core cable is used for a balanced three-phase system. It is clear that in the three-phase system there is a need of 120-degree phase shift in each wire which is not possible using a single core. So, for that purpose, we need to use cables having multiple cores.
- Armored or Non-Armored Cables
The installation environment of these low voltage power cables does undergo harsh environmental hazards. Due to which there is need to provide an outer layer to these cables for armoring purposes. Armoring helps the cable to remain unharmed and free from any environmental damage.
