Metal Enclosed Switchgears

Air insulated, metal enclosed modular switchgear for 7.2–36 kV networks — 630–1250 A, 16 / 20 / 25 kA.

Each panel is built from three compartments secured by switching and mechanical interlocks:

Low voltage compartment — all secondary circuits for measurement, protection, monitoring and communication.
Circuit breaker and cabling compartment — SF6 or vacuum circuit breaker, SF6 switch disconnector, current and voltage transformers, MV fuses, capacitive voltage divider, cable glands and connectors.
Busbar compartment — electrolytic copper busbars and insulators sized to the rated current.

The range covers incoming / outgoing, metering, transformer protection (load break switch + fuse) and bus coupling functions. Designed and tested to IEC 62271-200, IEC 62271-100, -102 and -105.
