Transformers and Substations

Custom arrangements of all kinds are available.

Unit Substation

Integrated unit substations are UL Listed, where applicable, and can be arranged to fit your exact requirements. Primary can be protected with load- interrupter, network protector or circuit breaker. Can be skid or trailer-mounted for portability.                

  • Indoor or outdoor
  • Dry or Liquid-cooled        
  • Up to 38kV Primary

Low Voltage Switchgear

... such as the secondary on the substation shown above is a PCI strength. Using insulated case power breakers or air circuit breakers, PCI low voltage gear sets the standard in quality construction and reliability. PCI keeps a large inventory of components and subassemblies on hand to facilitate those fast turnaround requirements.

Flexibility is a PCI cornerstone. We will build to match existing gear or transformer. We will use the customers choice of manufacturers for power breakers or air breakers. Height, depth, main buss location are also areas the customer can influence when desired.
