Product details

This European-style power box substation spans a broad 50–3150 kVA capacity band (200 kVA being the common selection) at a 35 kV rating. A single ventilated steel enclosure combines the high-voltage compartment, transformer compartment and low-voltage compartment, giving buyers container-style, fully integrated substation functionality suited to outdoor distribution work.

Design & Construction

  • Separate HV, transformer and LV rooms keep operation safer and servicing simpler
  • Dense perforation across the door panels moves heat out efficiently
  • Weatherproof sheet-steel housing topped with an overhanging flat roof
  • Fixed to a solid base frame that keeps the unit stable once installed outdoors

Applications

Well suited to industrial parks, residential and commercial developments, municipal power distribution, and medium-voltage utility grids.

Customisation Options

On request, we can adjust enclosure colour, capacity rating, voltage ratio, winding material (copper or aluminium), and internal compartment layout.

Ordering Information
