Cubicle Types

Sectionalising Metering cubicle with Disconnector, type SMD

Sectionalising metering cubicle, type SMD, is mainly used when medium voltage metering is required and/or when there is a requirement to sectionalise the switchgear. Cubicle is based on operation of two separetly operated 3-position, SFG type switch disconnectors.

Switch disconnectors are located at both ends of the secitonalised busbar. DIN size VT’s and CT’s are available on right hand side of the switchgear.


3-position switch disconnectors are interlocked with cubicle front door and access into cable compartment is possible only when both switch disconnectors are in earthed-position.
