8DJ10 secondary distributionswitchgear is a factory-assem-bled, type-tested, metal-enclosedswitchgear for indoor installation.

Typical uses

8DJ10 secondary distributionswitchgear is used for power dis-tribution in substations – evenunder severe environmental con-ditions, 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 underfloorsubstations

• Substations by pavements,e.g. in systems with extremelysmall construction widths, inparticular the basic versions ofschemes 10 and 71 in conurba-tions

• Substations with control aisle

Technical features

• Secondary distribution switch-gear design with up to 6 feeders

• Maintenance-free

• Climate-independent

• Three-pole primary enclosure,metal-enclosed

• Insulating gas SF6

• Gas-tight, welded switchgearvessel made of stainless steel,with welded-in bushings forelectrical connections andmechanical components

• Three-position switch-discon-nector with load-break andmake-proof earthing function

• Cable connection forbushings with outside cone

• Connection with cable plugs– In ring-main feeders with bolted

contact (M16)– In transformer feeders with

plug-in contact

• Option: Connection withconventional sealing ends

– For thermoplastic-insulatedcables via elbow adapterAKE 20/630 (make Siemens)

– For paper-insulated mass-im-pregnated cables via commer-cially available adapter systems

• Easy installation

Personal safety

• Safe-to-touch and hermeticallysealed primary enclosure

• HV HRC fuses and cable sealingends are only accessible whenfeeders are earthed

• Operation is only possiblewhen the enclosure is closed

• Logical mechanical interlocking

• Capacitive voltage detectionsystem for verification of safeisolation from supply

• Feeder earthing by means ofmake-proof earthing switches

Operating safety

• Hermetically sealed primary en-closure independent of environ-mental effects (dirt, moisture &small animals) – sealed for life:

– Welded switchgear vessel– Welded-in bushings and

operating mechanism

• Maintenance-free operatingmechanism parts (IEC 60 694/VDE 0670-1000)

• Switch operating mechanismsaccessible outside the switch-gear vessel

• Switchgear interlocking withlogical mechanical interlocking

Cost-efficiency

Extremely low “life-cycle costs”throughout the entire productservice life as a result of:

• Maintenance-free concept

• Climatic independence

• Minimum space requirement

• Maximum availability
