Unit Substations

Combining our extensive knowledge of switchgear with our Maxi-Cast and related transformer capabilities, Circuit Breaker Sales & Repair can provide quality secondary unit substations. We can provide a completely tested system from incoming primary switch, to the transformer, down to the low voltage gear.

Our typical secondary substation is:

  • Primary – 2400 V to 34,500 V fused load break switch GE, Westinghouse-Cutler-Hammer-Siemens
  • Transformer – oil or dry, 34,500 V primary down to a secondary of either 4160 V or 480 V
  • Secondary – 4160, 2400 or 480 V switchgear
