The European Compact Transformer Power Preinstalled BOX type substation

Short Description:

  • It is a complete set of new power transformer equipment ,which is widely used in power transformation system ,
  • It’s a combination of oil-immersed sealed power transformer and high and low voltage electrical components. Through structure optimization, the switchgear shall be miniaturized to extreme extent which greatly reduce the occupied area of the combined transformer with such advantages as small volume, low noise, reliable power supply, reasonable structure, convenient for installation, easy for operation etc.
  • It is widely used in residential quarters commercial centers stations industrial and mining enterprises airports railroads schools hospitals, high-rise buildings and places.
  • Meet standards :IEC62271-1,IEC62271-200,IEC62271-202,IEC60076,IEC61439, IEC60529,IEC62262, IEC60721.

The feature of European type box substation

1

Medium voltage Switchgear ·Medium voltage secondary switchgear including incoming feeder, outgoing feeder and transformer feeder
· The Medium voltage can be SF6 gas insulated type Ring main unitor  air insulated(Vacuum) switchgear main unitor High voltage load disconnecting switch + fuse  main unit
· In some cases - there is no Medium voltage switchgear, the Medium voltagecable is mounted directly on the transformer

2

Transformer

· Oil immersed hermetically sealed or Dry type transformers can be installed
· Transformer bushings can be located on top or side of transformer as per customer needs
· Wide range of transformer capacities up to 3500 kVA
· SafePack is designed to allow simple and easy transformer installation on site or integrated into the SafePack in the factory

3

Low voltage Switchboard

· Incoming feeder options can be direct connected, circuit breakers, fused disconnectors or Load Break Switches
· The LV busbar rating depends on the transformer rating
· Various number and ratings of outgoing feeders depending on transformer size and customer needs
· Equipment for metering, measuring and control available

4

Substation body

· mainly has metal material, stainless steel material , non -metal material ...which can be choosed by user and customers
