YB Series Prefabricated Transformer Substation(American Type Substation)

1)40 years' manufacturing experience with three subsidiaries 2) No. 1 and biggest factory 3)lowest price,best quality

Product overviews:

YB Series Prefabricated Substation is the self-developed product, which has absorbed the advanced technique all over the earth. As the power supplying unit, the high-voltage loading switch and the high-voltage fuses are have been set into the box-body. The phase uses the whole-sealed-structure. The oil-tools in the box have good ability of energy collecting and heat outputting. It has several advantages such as small, light, easy-installation, beauty-shape and so on. And it is widely used situation like city, hotel, hospital, etc.

Normal using conditions:Altitude ≤ 1000m

Environment temperature: the highest:40°C; the lowest: -35°C

Quakeproof:horizontal acceleration not larger than 3 4m/s2

Inclination of installationsite: no more than 3°

Installation condition: there should not have danger of fire or explosion, serious nasty, chemical etch and strenuous vibration. Wind ≤ 35m s ( not larger than 700pa )Relative humidity: the annual average value is no lager than 95%. monthly value is no larger than 95%Vertical acceleration:0.15m/s2Beyond the conditions above, please consult with our company.

Product structure:1.It's with small volume and compact conformation. It covers just about 1/3 to 1/5 of the usual European-style substations, which have same capacity with it. 2.It's full-sealed and all-insulated. And it uses the S11-type transformer, which has low-wastage, low-voice and strong ability of overloading. This box includes 3 parts: high-voltage-room, low-voltage-room and transformer. 3.The high voltage side uses V-style or T-style loading switch. And it adds the 2-grade fuses, which can be used into the ring-network and terminal. 4.Several components, like oil-temperature gauge, oil-level indicator, pressure gauge, pressure-dump valve and fuel-outlet valve, have been set in the high-voltage room to monitor the running of the transformer. The high-voltage inlet wire uses the cable plug, which can be equipped with ZnO lightning arrester. 5.To meet your requirements, we can add the low-pressure measurement and divided line-output to satisfy the low-pressure-requirements. 6.The transformer use the corrugated sheets to radiate. After special processing, it has strong corrosion resistance and multiform out-shape.

Note :Side of the rated working voltage :and 6.3 10kv. low side, and the rated working voltage : 3 4kv

Regulated pressure range:± Five % ± 2 by 2.5%, or the user, group attached the label: y, yno or d, yn11

Technical requirements of foundation drawing:

1.If the earth mat is not set as the picture above, it can be set in another way. But the earth resistance should be less than 4Ω.

2.The earth electrode and the earth connecting points is with electric welding. The welding parts should be brushed with coal tar.

3. To protect the safety of the transformers, you can set the fence around.
