This product has the advantages of smaller volume,compact structure,high heat insulation and ventilation function,dust-proof,prevent small animal to enter,moist-proof,beautiful appearance and convenient to maintenance, we can choose cold-rolled steel plate,compound color plate and other material to make up enclosure.
All the black material of substation are taken surface anticorrosive treatment, it will guarantee that product will be not corroded for a long time.
HV side use HXGN26-12(F), with complete operation mistake prevention function.

Structure and appearance:
1. Substation base plate and supporting structure adopt U-steel and angle steel, it has higher mechanical intensity, enclosure adopts cold-rolled steel plate or compound color plate. It has beautiful appearance that there are no threaded connection or rivet connection from the exposed surface.
2. Use clapboard to divide into independent room between each room of substation.
3. In order to observe and maintain, LV room and HV room have lighting device.
4. Reversible connecting parts of substation adopt rubber belt to seal, with good damp-proof capacity.
5. HV room is equipped with HXGN26-12(F) RMU, and also with SF6 load switch,fuse(adopts circuit breaker,lighting arrester,earth switch and mechanical interlock device if it required,.
6. If adopts HV measuring, it is also equipped with voltage transformer,current transformer and measuring meter.
7. Each LV elements in LV room should be frontal arranged.
8.Instrument room on the top, it has observing window on the front. each element has independent and removable plate,can be convenient to maintain.
According to the requirement of reactive compensation, it should be equipped electric device, its capacity is 15~20% of transformer.
