FIELD: electrical engineering.
SUBSTANCE: invention relates to high-voltage electrical transmission cables or overhead cables for transporting electricity, called overhead power lines, and can be used to transmit electrical energy of increased frequency. High voltage three-phase coaxial cable consists of four conductors for high frequency three-phase current. The first conductor is made of single or stranded copper or aluminum wires and is located in the center of a high-voltage three-phase coaxial cable. Subsequent conductors are made of solid or braided, copper or aluminum wires, superimposed concentrically on the insulation of the previous conductor. Three conductors are insulated with PTFE, and the outer insulating sheath is made of light-stabilized cross-linked polyethylene.
EFFECT: reducing the electrical resistance of a high-voltage three-phase coaxial cable.
