Electrical cables are well-known for their stability and ability to transmit power and voltage efficiently. Mostly, the main focus is on providing better sustainability and reliability of the surrounding environment. Mostly, the electrical cables could be classified with respect to the voltages that they are transferring.
Following are the different types of tension cables used in electricity transmission.
- Low tension cable
- High tension cable
- Super tension cable
- Extra high tension cable
- Extra super voltage power cable
Low Tension Cable
Low tension cables are used for transmitting the voltages below than 1 KV. Because the cable is not prone to any special electrostatic stress its construction is kept normal. Even the insulation is very simple in which a paper is impregnated using oil. Its viscosity increases by applying the resin and it also avoids damage. Over the outer sheath layer, there is another layer which keeps the cable protected from moisture and any environmental damage.
High Tension Cable
Medium and high tension cables are used for transmitting the voltages in the range of up to 66 KV. These cables comprise of three core cables i.e. multicore cables are used for high tension cable. Three phase medium is transmitted using high tension cables.
Super Tension Cables
There are certain cables which have the ability to transmit electricity above the range from 66KV. These cables are also referred to as screened cables or also called as super tension cables. These cables are intended to transmit 132 KV to 275 KV voltages.
Extra High Tension Cables
Extra high tension cables are usually used as the core technology to transmit power lines having an AC 220 kV-400 kV. XLPE cables have a proven record due to which it has been serving the purpose of transmitting power at such a high voltage for over 20 years.
