Combining our extensive knowledge of switchgear with our Maxi-Cast and related transformer capabilities, Circuit Breaker Sales 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 volts to 34,500 volts fused load break switch GE, Westinghouse-Cutler-Hammer-Siemens
- Transformer – oil or dry, 34,500 volt primary down to a secondary of either 4160 volts or 480 volts
- Secondary – 4160, 2400 or 480 V switchgear
