Product Description
Outdoor Prefabricated Transformer Substation. EU or Us Style Oil Immersed Pad Mounted Transformer
Product features
1. Small size and compact structure. The floor area is only about 1/3-1/5 of the floor area of domestic European box type substation with the same capacity. Fully sealed, fully insulated structure, no insulation distance, safe and reliable, excellent transformer performance, low loss.
2. Equip S11 type transformer with low noise and strong overload capacity. It is divided into three parts: main high-voltage chamber, low-voltage chamber and transformer. The conventional layout is the Chinese character font (YBP). The high-voltage side adopts V-type or T-type load switch and two-stage fuse protection, which can be used for loop network and terminal. The power supply mode is flexible and reliable.
3. The high voltage chamber is equipped with oil humidity gauge, oil signal gauge, pressure gauge, pressure relief valve, oil drain valve and other components to monitor the operation of the transformer.
4. High voltage incoming line adopts cable plug and can be equipped with zinc oxide arrester to meet various low-voltage outgoing requirements. According to user requirements, low-voltage metering and shunt outgoing line can be added.
5. The transformer adopts corrugated fins for heat dissipation. After special process treatment, it has strong anti-corrosion ability, various shapes and structures. It can be made of ordinary steel plate, stainless steel and other plates.
