General
UNS-SBT series products is a kind of complete solution which assembles the MV RMU, transformer, LV distribution equipment together according to fixed connection scheme. This series substation is suitable for neighborhood unit, hotel, large-scale work site and high building that the voltage is 1 1 kV 15/22kV/33kV/, the frequency is 50Hz or 60Hz and the capacity is under 2500kvA.
For MV switchgear, we can use AIS (UN-P 28, UN-AM) or GIS (UN-GM6) and SIS (UN-SMS).
For Transformer, we can use Oil immersed type or Epoxy resin type.
For LV switchgear, we have GGD, or XL, different type of LV switchgear.
Standard
All UNISUN transformers are in conformity with IEC standards, Transformers in conformity with specific country standards can also be supplied. (IEEE, GB)
