new typeYB -12 European Type Substation

1.GB/T17467 SD320 IEC61330 2.CE CQC CCC ISO9001 ISO14001 OHSAS 18001 BV 3.high integration, small size, safe

1.    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 switch 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, automatic reactive capacity, capacity with no touched point and connector can be throw in and throw out.

       Pre-fabricated substation

3.    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-organsm, 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 environnment and condition. It can adopt different structures and covering material.

4.    Ambient Condition

1.    Ambient  temperature: -25°C~+40°C

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.
