General
YB() series products is a kind of set of equipment which assembles the MV switch apparatus, 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 12kV /24kV/36kV/40.5kV, the frequency is 50Hz and the capacity is under 2500kvA.

Service environment
a) Air temperature: Maximum temperature: +50℃; Minimum temperature:-55℃
b) Humidity: Monthly average humidity 95%; Daily average humidity 90% .
c) Altitude above sea level: Maximum installation altitude: 2500m
d) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.
e) No frequent violent shake

Main Designation Characteristics

l     The crust of the substation is designed according to the foreign advanced technology and physical reality. We provide many kinds of crust material such as aluminum alloy steel composite stainless steel board and non metal material(glass fiber).
l     The HV side use charge switch or vacuum circuit breaker. The transformer could be oil type hermetically-sealed type and dry type.
l     The proof of the box is double layers structure and between the layers is filled with foam.There are independent boards in HV and LV room, and in the transformer room will install auto thermal controller heater and cooling equipment.
Note: we offer special customized products according to client’s requirement.
