High Voltage burning unit SVP-05C is designed for burning (destroying the soldered joint with resistance close to zero, in the point where a high voltage cable core short circuits to the shell or another core) the defective insulation of power cables, with subsequent afterburning, in order to destroy the contact resistance in the defective point, which allows for subsequent application of the known methods for determining the distance to the fault and fault location directly on the cable track.
