Package Sub-station

Emirates Transformer & Switchgear has developed a reputation for designing, manufacturing, and supplying quality package substations. The unit comprises of a distribution oil transformer, HV ring main unit, and LV feeder pillar mounted on one common platform to make a compact and easy design layout.

Our flexible designs accommodate various RMU and feeder pillar positions to meet individual customer requirements and substation housing options. All our package substations are weatherproof and suited for either indoor or outdoor locations.

Standard ratings are 500, 1000, 1500kVA although we offer other ratings up to a maximum of 3000kVA. Package substations provide operators with reductions in cost, footprint, and cable run lengths.

Unit Combinations:

  • transformer & LV feeder pillar
  • transformer & HV ring main unit (RMU)
  • transformer LV feeder pillar & HV ring main unit (RMU)
