Air Insulated Switchgear

Cubicle Types

Sectionalising cubicle with Fuse, type SEF

The cubicle type SEF is used when a sectionalising cubicle with fuse protection is needed, or if there is a requirement for measuring on the transformer feeder. For fuse earthing, the integrated earthing switch operates on the upstream side and separate earthing switch operates

on the downstream side of the fuses.

The mechanism used is a double spring mechanism with automatic fuse tripping. Access to cable compartment is only possible in earthed-position. A visible check of the “open” and “earthed” positions

is available through inspection windows placed in the low voltage compartment. Busbar connections to both left and right are possible.
