Electricity is transmitted at high voltages (115 kV or above) to reduce the energy loss which occurs in long-distance transmission. Power is usually transmitted through overhead power lines. Underground transmission is sometimes used in urban areas or environmentally sensitive locations.
In respect to this, what is a high tension cable?
A high-voltage cable (HV cable) is a cable used for electric power transmission at high voltage. A cable includes a conductor and insulation, and is suitable for being run underground or underwater. This is in contrast to an overhead line, which does not have insulation.
What is high tension electricity?
Having a high voltage, or designed to work at or sustain high voltages. High-tension wires used to carry electrical power over long distances sustain voltages over 200,000 volts. Compare low-tension.
What is a high tension line?
High-voltage transmission lines are used to transmit electric power over relatively long distances, usually from a central generating station to main substations. They are also used for electric power transmission from one central station to another for load sharing.
