Critical Power

Switchgear, Panelboards & Subpanels

Distribution gear from the service entrance down to the subpanel, specified as part of the protection scheme rather than as a commodity.

Switchgear is where the protection scheme stops being a drawing and starts being equipment. Access supplies low, medium and high voltage distribution gear — switchgear, switchboards, panelboards and subpanels — and specifies it against the coordination study rather than against a schedule of ratings, so the device that clears a fault is the one that was supposed to.

What we supply

  • Low voltage switchgear and switchboards
  • Medium voltage switchgear
  • Gas-insulated switchgear — 145kV, 252kV and 363kV
  • Panelboards and subpanels
  • Dead-tank high-voltage circuit breakers
  • Paralleling and power control switchgear

Who we represent for switchgear, panelboards & subpanels

The outcome

Specified correctly, supported for its lifecycle.

Gear chosen against the coordination study clears the smallest possible section of the system, which is the difference between one panel going dark and a building going dark. Buying it from the same place as the power and thermal equipment around it also means one lead time to manage instead of three.
