They are designed for switching on and off circuit sections with voltage up to 10 kV and rated current 400, 630 and 1000 A. High-voltage disconnectorsPV, RVZ, RVFZ, RVO, are used to create a visible break separating the equipment removed from the work from the conductive parts,  which are energized. The disconnectors do not have any inductive devices and are therefore intended for switching on and off electrical circuits in the absence of load current.
