Multi-Tap Transformer Containerised Substation Hire

We have a hire fleet of multi-tap 6.3MVA 20-foot ISO containerised substations with integral switchgear and adjustable protection, purpose built to give various high voltage 50hz or 60hz outputs from parallel multi-generator input.

Maintained on standby for immediate dispatch, these highly versatile units can be used from applications from 3kV to 26.4kV. With the ability to operate at 50Hz and 60Hz they can be used for stepping voltage up (YNyn0) or down (Dyn11) as required and are equipped with fans to allow up-rating to 7.5MVA on ONAF cooling.

Constructed to withstand the most rigorous industrial demands and environments, these robust and easy to transport units provide highly versatile power output from an impressively small footprint.

Their versatile nature make these units highly suitable for a variety of emergency or planned temporary power requirements.

We also offer standard distribution, power and cast resin transformer and switchgear hire options.

Specifications

Slaters multi-tap transformer containerised substations:

  • Contain a 6300kVA multitapped high voltage transformer suitable for step up from star connected 400V 50hz or 480V 60hz inputs
  • Consist of 2x multi-tap 3150kVA double wound oil cooled transformers, arranged for individual or parallel operation
  • Are mounted in a 20ft ISO container, with end and side access doors and cable access points

Substation Type ‘A’ 20kV
Rated 50hz HV outputs, star connected : 22, 20, 18, 15, 11, 10, 9 kV
Rated 50hz HV outputs, delta connected : 12.7, 11.5, 10.4, 6.3, 5.8, 5.2 kV

Rated 60hz HV outputs, star connected : 26.4, 24, 21.6, 13.2, 12, 10.8 kV
Rated 60hz HV outputs, delta connected : 15.2, 13.8, 12.5, 7.6, 6.9, 6.2 kV

Transformers are fully rated across the range except for the 15kV 50hz output which is 2x 2500kVA
Transformers are fitted with cooling fans and each will uprate to 3750kVA with ONAF cooling

The high voltage output is distributed through a 4 panel switchboard comprising 2x 630A 24kV rated isolators and 2x 630A 24kV rated vacuum circuit breakers cabled from the transformers. Low voltage feed is through 6x 2500A 4 pole isolators for supply from parallel generators.
