Product Description
★★S11 Series 10kV Non-excitation Voltage-regulating Transformer★★
Product Description
The products implement the National Standard GB1094-2013 Power Transformer and GB / T6451-2015 Three-phase Oil-immersed Power Transformer Technical Parameters and Requirements, and are recommended as the major equipment products for the national urban and rural power grid construction and retrofit by the State Economic and Trade
Commission.
S11 series transformer is one kind of low loss copper winding product.It adopts high quality material, especially applying the new technology and new material to the insulation of the coil and transformer body, thus the no-load and the load loss are obviously reduced, the performance and structure are more reliable and superior. |

Product Features
★
Good Economic Performance
Based on S9 series, the no-load loss for S11 series products decreased averagely 10.3%, no-load current decreased 22.4%.
The three-phase oil immersed idstribution transformer adpots new type insulation structure and makes the shot-circuit resistance strong.
Long Service Life
Transformer tank adopts fully sealed structure, fuel tank and tank rim can be connected by bolts or welded firmly, the transformer oil doesn't contact with the air, extending the service life.
High Operational Reliability
Improve the relevant sealing parts for the fuel tank, increase the reliability and advance the technical level to ensure the reliability of the seal.
Small Installation Area
S11-M series of transformer tank uses the corrugated plate radiator. when the oil temperature changes, the corrugated board expands from the heat and contracts from the cold, which can replace the role of the oil conservator, the corrugated plate type fuel tank has beautiful appearance, less occupied area.
