Electric power transmission is the bulk transfer of electrical energy from generating power plants to high voltage substations. Transmission lines, when interconnected, become the transmission networks, typically referred to as the power grid.
Electricity is transmitted at high voltages to reduce the amount of energy lost in long distance transmission. Power is usually transmitted through overhead power lines, although underground transmission lines are sometimes used. High voltage transmission lines are made up of either copper or aluminum conducting lines suspended by towers.
Most transmission lines use high voltage three-phase alternating current (AC). High voltage direct current (HVDC) technology can be used to improve efficiency over extremely long distances.
Beta has completed numerous projects that include medium and high voltage transmission lines, both overhead and underground, in a variety of terrains.
Beta’s electrical engineering and civil engineering teams design and build high voltage projects across the country, specializing in EPC services for gas insulated substations (GIS), switchyards and substations, FACTS and high voltage transmission lines.
