8DJH With Siemens cooperation download

Medium Voltage Switchgear for Secondary Distribution System Up to 24KV, Gas Insulated



8DJH switchgear is factory-assembled, type-tested, 3-pole metal-enclosed, single-busbar switchgear for indoor installation:

  • Up to 24 kV
  • Feeder currents up to 630 A
  • Busbar current 630 A

Typical uses

8DJH switchgear is used – even under severe ambient conditions – for power distribution in secondary distribution systems, such as
Substations, customer transfer substations, distribution substations and switching substations of power supply and public utilities
Industrial plants, such as:

  • Wind power stations, high-rise buildings, airports
  • Lignite open-cast mines, underground railway stations
  • Sewage treatment plants, port facilities
  • Traction power supply systems
  • Automobile industry, petroleum industry
  • Chemical industry, cement industry.


8DJH switchgear is classified according to IEC/EN 62271-200 /VDE 0671-200.

Modular design

  • Individual panels and panel blocks can be lined up and extended at will – without gas work on site
  • Low-voltage compartment available in 3 overall heights, wiring to the panel via plug connectors.

Extremely low “life-cycle costs” throughout the entire product service life thanks to:

  • Maintenance-free design
  • Climatic independence
  • Minimum space requirements
  • Maximum availability.


  • Type and routine-tested
  • Standardized, NC production processes
  • More than 500,000 switchgear panels in operation in hermetically welded design.

Quality and environment

  • Quality and environmental management system according to DIN EN ISO 9001 and DIN EN ISO 14001.

Personal safety

  • Safe-to-touch and hermetically sealed primary enclosure
  • HV HRC fuses and cable sealing ends are only accessible when outgoing feeders are earthed
  • Operation only possible when enclosure is closed
  • Logical mechanical interlocking
  • Capacitive voltage detecting system to verify safe isolation from supply
  • Feeder earthing via make-proof earthing switches.


  • Maintenance-free components
  • Complete switchgear climate-independent
  • Three-pole primary enclosure, metal-enclosed
  • Insulating gas SF6
  • Welded switchgear vessel without seals, made of stainless steel, with welded-in bushings for electrical connections and mechanical components
  • Three-position switch-disconnector with load-break function and make-proof earthing function
  • Cable connection for bushings with outside cone
  • Connection with cable plugs
    • In ring-main feeders and circuit-breaker feeders with bolted contact (M16)
    • In transformer feeders with plug-in contact or optionally with bolted contact (M16)
  • Pressure relief downwards, optionally to the rear or upwards via pressure absorber systems
  • Wall-standing arrangement, optionally free-standing arrangement.
