HIGH VOLTAGE UNITS of FASG2-10 type
FASG cabinet consists of a rigid metal case inside which all the equipment is placed. For safe maintenance and localization of accidents, the enclosure is divided into compartments by metal partitions and automatically closing shutters. HV switch with drive is mounted on draw-out element (trolley). In upper and lower parts of the trolley there are movable disconnecting contacts, which, when rolling trolley into the cabinet, are closed with bus (upper) and linear (lower) fixed contacts. When rolling out the trolley with a pre-disconnected switch, detachable contacts are disconnected, and the switch is disconnected from the collecting buses and cable inlets.
When the trolley is outside the cabinet, it provides an easy access to switch and its drive for repair; if the quick replacement is necessary, it may be replaced with the other similar switch installed on the same trolley.
The roll-out element of cabinet has three positions:
working position - trolley is in the cabinet, primary and secondary circuits are closed;
testing (control) position - trolley in the cabinet, but the primary and secondarycircuits are open;
repair position - trolley is outside the cabinet, primary and secondary circuits are open.

The cubicle switchboard FASG2-10 is designed to receive and distribute power of three-phase AC of industrial frequency in networks with isolated or grounded through the arc suppression reactor neutral.
The cubicle switchboard ready-to-operate is made in metal case in which vacuum power switch, support-type current transformers TOL, OLS and/or ZNOL transformers, overvoltage limiters and the other equipment are installed.
The cells can be either stand-alone with the possibility of expansion, or integrated into the integral distribution points.
