Product Details

The 11kV–33kV VCB switchgear is engineered for medium-voltage substations, industrial networks and utility power distribution. Its armoured metal-clad construction provides segregated compartments for the circuit breaker, busbar, cable connection and low-voltage control sections. A vacuum circuit breaker provides dependable switching and fault interruption, while protection relays, CTs and PTs can be configured according to system requirements. The switchgear supports customized incomer, feeder, bus coupler and transformer protection panels. Engineering can be based on customer SLDs, electrical parameters and local grid requirements.

Applications

Ideal for substations, mining projects, utility distribution networks, industrial plants, power generation facilities and large infrastructure projects. It can be applied to transformer incoming protection, outgoing feeders, bus sectionalizing and industrial load distribution. The 11kV and 33kV configurations are particularly suitable for African and Southeast Asian power infrastructure where medium-voltage distribution and substation equipment are required. Complete switchgear lineups can be supplied for project-based applications.
