METHOD FOR MELTING ICE ON OVERHEAD POWER LINE WIRES WITHOUT INTERRUPTION OF POWER SUPPLY TO CONSUMERS Russian patent published in 2022 - IPC H02G7/16 

FIELD: power industry.

SUBSTANCE: invention relates to the field of electric power. According to the method, a power supply is installed at one end of the line. The overhead line consists of at least two lines of composite wires connected to at least one consumer load. The composite wire contains at least one heating core and at least one current-carrying core, which are in thermal contact, but are electrically isolated from each other by a dielectric layer. The current-carrying core of the composite wire is connected directly to the source on one side and to the consumer on the other side, and the heating core of the composite wire, in accordance with the selected switching scheme, is connected through the switching element on one side to its current-carrying core, and the other end to the current-carrying core of the composite wire of the other line either directly or through the heating core of the composite wire of another line. During the melting of ice, the heating cores are connected to the power source in parallel with the load of the consumer.

EFFECT: increase in the reliability of overhead power lines in adverse weather conditions.
