Product characteristics

The basic structure of the substation is classified into “目”and “品”shapes.The box framework is welded with high-quality channel steel and angle steel,with high mechanical strength.The box is made of aluminum alloy profiles,which have good anti-corrosion ability.The overall beautiful appearance can be coordinated with the surrounding environment through painting and coloring.The carefully designed bottom lifting device provides great convenience for installation,transportation and movement.

There are independent high-voltage room,transformer room and low-voltage room inside the substation,and the lighting in each room automatically opens with the opening of the   door.The high-voltage room is equipped with high-voltage ring main unit,which can be   selected as compressed air type or vacuum load switch according to user needs,and it also has the "five prevention"function.When current-limiting high-voltage fuse is used,if a phase fuse is blown, the load switch will automatically open,avoiding faults caused by phase loss operation.

The transformer room adopts natural ventilation and automatic control forced cooling device,with exhaust system that automatically controls with temperature changes,which can effectively control and reduce the temperature inside the box to meet operational requirement.According to user requirements,anti- condensation device can also be used,which can be easily accessed from both sides of the transformer room through the door along the track.The box  material can prevent rainwater and dirt from entering,and has the conditions for long-term outdoor use,ensuring anti-corrosion,waterproof and dustproof performance,long service life,simple maintenance,as well as beautiful appearance.

①Transformers can be dry-type or oil immersed type.

②The low voltage room has the overall function of low-voltage switchgear,which can be selected and combined by users at will.。

③Outer shell material:including composite plate,stainless steel composite plate,aluminum zinc plated plate,stainless steel plate and metal carved plate.

④Structural feature:The high-voltage structure is reasonable and compact,and HXGN17 and XGN15 ring main units can be selected,all of which have five prevention interlocking functions.The natural ventilation and automatic ventilation cooling system for transformer can be applied to dry-type and oil-type  transformers,

⑤Low voltage room:Multiple structural distribution solutions can be adopted according to user requirements,including power distribution,lighting distribution,reactive power automatic compensation,energy metering and other functions,and it's equipped with an automatic lighting system.
