Secondary Unit Substations
Our vast knowledge of switchgear combined with our transformer capabilities allows us to provide secondary unit subs.
We can provide a completely tested system from incoming primary switch, to the transformer, down to the low voltage gear.
Our typical secondary sub 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
