IEC Medium Voltage VCB Armoured Switchgear 12kV 36kV Withdrawable Metal Clad Switchgear

Product Details

This IEC medium-voltage VCB switchgear combines an armoured metal-clad enclosure with a withdrawable vacuum circuit breaker for demanding power distribution applications. The withdrawable breaker compartment allows the VCB to be moved between service, test and isolated positions, supporting safer operation and easier maintenance. The cabinet can integrate CTs, PTs, protection relays, bus couplers and cable compartments according to the project design. Voltage class, current rating, short-circuit capacity and panel arrangement can be customized. The solution is suitable for grid, renewable energy and industrial MV networks requiring reliable switching and protection.

Applications

Designed for power grids, substations, solar and wind power projects, industrial plants, mining facilities and large energy infrastructure. It can serve as incoming switchgear, feeder protection, transformer protection or bus sectionalizing equipment. The withdrawable VCB configuration is especially suitable for projects where maintenance flexibility, equipment availability and operational safety are important. Customized panel lineups can be supplied according to the customer's SLD, grid code and project-specific electrical requirements.
