Switchgear Type 8DH10

Switchgear Type 8DH10, Insulating gas SF6

8DH10 switchgear is a factory-assembled, type-tested, metal enclosed switchgear for indoor installation.

ical data :

  • Rated voltages up to 24 kV
  • Rated short-time withstand current up to 25 kA
  • Rated normal current of feeders
    • up to 630A, for cable field
    • up to 200A, for transformer field
  • Rated normal current of busbar up to 1250A

Typical uses

8DH10 switchgear is used for power distribution in substations–even under severe environmental conditions, such as:

  • Industrial environments
  • Damp, sandy or dusty areas
  • Simple outdoor substations

Samples of use

  • Compact Wind power stations
  • High-rise buildings
  • Airports
  • Lignite open-cast mines
  • Underground railway stations
  • Sewage treatment plants
  • Port facilities
  • Automobile industry
  • Petroleum industry
  • Chemical industry
  • Cement industry
  • Unit-type heating power stations
  • Textile, paper and food industry

Security of operation and reliability

  • Hermetically sealed primary enclosure, in dependent of environmental effects such as pollution, humidity and small animals, sealed for life:

–    Welded switchgear vessel
–    Welded-in bushings and operating mechanism

  • HV HRC fuses and cable sealing end sare only accessible when outgoing feeders are earthed
  • Operating mechanism parts maintenance-free - VDE 0670, IEC 60 694
  • Operation only possible when enclosure is closed



  • Individual panels and panel blocks can be freely combined and extended – without gas work on site
  • Three-pole primary enclosure, metal-enclosed,
  • Insulating gas SF6
  • Welded switchgear vessel with-outseals, made of stainless steel, with welded-in bushings for electrical connections and mechanical components
  • Maintenance-free
  • Climate-independent
  • Three-position switch-disconnector with load-break and make-proof earthing function
  • Easy installation
