8DJ20 switchgear is a factory-

assembled, type-tested, metal-

enclosed switchgear for indoor

installation.

Typ ic al us es

power distribution in substations

– even under severe environmen

-

tal conditions, such as:

•

Industrial environments

•

Damp, sandy or dusty areas

•

Simple outdoor substations

Main uses

•

Compact substations

•

Compact transformer substations,

e. g. for wind power stations

•

Garage and vault substations

•

Underground and underfloor

substations

•

Sidewalk substations, e.g.

containing switchgear with a

very small overall width – in

particular the basic versions

of schemes 10, 32 and 71 –

in conurbations

•
