Application:Yb27 series substation is an American type combined substation with function of high voltage control, protection, power transformation and distribution. Usually used in urban and rural power distribution system. The high voltage load switch and high voltage fuse of this product are installed in the oil of the transformer, with the two structures: in same case with the transformer and in different case with transformer. It can be used in high-rise buildings, building in urban and rural areas, residential communities, high-tech development areas, small and medium size factories, mining areas, oilfields, temporary features sites, and other premises.

Standard: IEC1330

Features

1. Compact structure with small volume, the volume is 1/3-1/5 of European style substation in same capacity. It reduce the floor space efficiently.

2. Whole sealing and full insulated structure ,no need insulation distance. This can protect personal safety

3. High voltage wiring can used both in looped network and terminal with high reliability and flexibility

4. The transformer is with excellence performance, low loss,low Noise,lowtemperature rise, high overload capacity, strong impact resistant ability and highanti-short circuit capacity .

5. connector. Both can equiped with all insulated ZnO lightning conductor.200A elbow connector can use with load plug and with the function of insulation switch.
