FIELD: energy.
SUBSTANCE: in the known device the backup power line, comprising a steel intermediate support, traverses a hung them with garlands hanging insulators and conductors phase and switching switches are invited back stage to perform a split into three components conductor combined in emergency mode switching switches and connected instead of the faulty phase . In normal operation, the circuit overhead line digested his backup phase switching switches attached symmetrically to the phases of the working circuit overhead line, providing the nominal voltage on the line. In normal mode, attached symmetrically to the phases of the working circuit overhead line split phase increases by 60% the capacity of the working circuit transmission line.
EFFECT: deskew phase voltage operation circuit overhead line (VL).
