8BK80 metal clad switchgear is of horizontal isolation & horizontal draw out type, suitable for easy extension of switchgear in both directions, for system voltage 36kV.

The switchgear is designed for single busbar system & is fully compartmentalized. The design incorporates the set of interlocks for safe operation of switchgear.

The switchgear is suitable for use as distribution unit for switching load at substations of electric supply companies as well as for power stations & industrial plants.

  • True metal-clad and air insulated switchgear
  • Single Busbar System
  • Circuit breaker mounted on withdrawable truck

Switchgear Layout

Circuit-breaker panels are used as incoming panels or feeder panels. The 3AH vacuum circuit-breaker is mounted on a truck for racking the circuit-breaker into the panel. The vacuum circuit-breaker can break all the rated normal and short-circuit currents specified on the rating plate.

Basic components
Metal partitions subdivide each panel into:

  • Truck with 3AH vacuum circuit-breaker
  • Panel connection for cables (cable & CT compartment)
  • Busbar compartment
  • Low-voltage compartment

Optional components

  • Insulated busbar system
  • Current transformers at the cable feeder as
    • Ring-core current transformers
    • Block-type current transformers
  • Current transformers at the busbar
    • Block-type current transformers
  • Voltage transformers
    • At the cable feeder
    • At the busbar
    • Withdrawable type, mounted on the truck
  • Surge arresters
  • Busbar earthing switch
  • Sockets for capacitive voltage detection systems
  • Feeder earthing switch
