YB-12 Prefabricated Substation

Composition
The covering material are: colored steel plate, cold rolled plate, stainless steel, glass-fabric special cement, aluminum alloy and copper aluminum zinc plate. The insulating medium of medium voltage s witch device: SF6, atmosphere and vacuum. transformer: oil and dry mode. Low voltage power device-main switch: universal breaker, intelligent breaker and outgoing switch. No flashover plastic switch, auto mastic reactive capacity. capacity with no touched point and
connector can be throw in and throw out.

Product feature
1. There are automatic temperature controlling device, exhaust blower, heating and dew against device in the substation.
2. Characteristic: Fastness, heat insulation, ventilation, good performance, guards against the micro-organism, moisture proof, nice looking, convenient maintenance, occupies little ground and so on.
3. At the high voltage side, use breaking switch and current limited fuse as the protector for the transformer. When the current limited fuse was fused, the three-phase load breaking switch will cut off. The high voltage side also can adopt the vacuum breaker as the protector.
4. At the bottom of the transformer, the pony truck can be installed, which can pass in and out freely for the inspection.
5. The wiring and arrangement are various; In terms of different environment and condition, it ca n ado pt different structure res and covering material.

Ambient condition
1. Ambient temperature: -25℃~+40℃;
2. Altitude:≤1000m;
3. Wind pressure: ≤700Pa;
4. Humidity: daily average≤95%, monthly average≤90%;
5. Pollution degree:Ⅳ;
6. Earthquake intensity: 8 degree;
7. Occasions without fiercely shake and corrosiveness, as well as without flaming and explosive matter, the verticality is no more than 3 degree.
