High voltage compartment

The HV side use charge switch or vacuum circuit breaker.
HV switchgear type: SF6 RMU,FZN series air insulated vacuum RMU or terminal switchgear.
oil type transformer
Suggest model: S10-M,SC(B)10,serials transformer
Transformer capacity general range from 30-2000kVA. This part can be made based on client's requirement.

Low voltage compartment
Low voltage compartment can adopt low voltage switch box, like GGD, GCK. This switchgear divide into measuring room, isolation switch unit, capacitance compensation unit. Switch brand can use imported brand or domestic brand, it depends on client's requirement.


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 | ||
