Unitized Pad Mounts

Pioneer manufactures low profile, tamper proof, totally integrated pad mount substations, called unitized pad mounts. These units are used at commercial sites such as apartment complexes, shopping centres, office complexes, industrial parks, factories, airports, hospitals, schools and military installations. The units have an aesthetic appearance and avoid the necessity of fences and overhead electrical structures.

Generally, any end user buying power at the primary voltage level, or owning and operating their own HV distribution system should consider unitized pad mounts. This design eliminates hot sticks so that non-utility personnel can switch off the unit. Inside the compartment an external load break switch on the HV side can be checked through a viewing window to see if the blades are in the open or closed position. a mechanical interlock system prevents access to the fuse compartment unless the load break switch is in the open position. Sizes are as follows:

5kV CLASS60kV BILUP TO 3MVA
15kV CLASS95kV BILUP TO 5MVA
25kV CLASS125 & 150kV BILUP TO 5MVA
27.6kV CLASS150kV BILUP TO 5MVA
34.5kV CLASS150kV BILUP TO 5MVA

The units conform with CSA, ANSI or EEMAC applicable standards. we can provide:

  • fused or unfused load break switch on HV side
  • secondary metering compartments
  • LV distribution center (fusable switches, enclosed CB, metering)
  • shunt trip coil
  • lightning arresters
  • key interlocks
  • various gauges
  • fan cooling or provision
  • 55/65 degree C temperature rise


Platform Mounts

We offer a range of platform mounted units from 250 kVA to 1000 kVA with voltages up to 46kv, 250kv BIL. these units can also be supplied for substation installation up to 2.5 MVA. We offer the following options:

  • special LV terminations like throat or junction box
  • dual voltages up to a ratio of 3:1
  • tap switches
  • various gauges
  • skid base

Grounding, Rectifier and Vault-Type Transformers

Pioneer offers a number of other specialized transformer units, engineered and manufactured in a range of sizes and to customer specifications including grounding, rectifier and vault-types, among others.
