Short-circuiting set 420 kV for overhead lines

The short-circuiting set is designed for short-circuiting and earthing of the circuit, usually three phases in HV systems with voltage up to 420 kV. It is composed of three pieces of conductor clamps, earthing clamps, short-circuiting cables and one insulating stick to enable safe fitting and tightening of the conductor clamps. The short-circuiting set is type-tested and complies with EN 61230 and PNE 35 9700.
