RFVZ-10/400 disconnectors (630, 1000)

RVFZ disconnectors differ in existence of insulators through passage. RVFZ disconnectors - 10/630 I UHL3 are intended for switching energized of sites of an electric chain in the absence of load current and for change of schemes of connection, for ensuring safe works on the disconnected site, for inclusion and shutdown of charging currents of air and cable lines, single current of transformers and currents of small loadings
