Product Description

The products implement the National Standard GB1094-2013 Power Transformerand GB / T6451-2015 Three-phase Oil-immersed Power Transformer Technical Parameters and Requirements, and are recommended asthe major equipment products for the national urban and rural power grid construction and retrofit by the State Economic and Trade Commission.

S11 series transformer adopts high quality material for copper winding, especially applying the new technology and new material for the coil insulation and active parts, 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

The no-load loss for S11 series products decreased 10.3% averagely, no-load current decreased 22.4%based on S9 series.

● Long Service Life

Transformer tank adopts hermetical structure, tank and tank cover can be connected by bolts or welded firmly, the transformer oil won’t contact with air,so that extend the service life effectively.

● High Operation Reliability

Improve the relevant sealing parts for the tank, increase the reliability and advance the technical level to ensure the reliability of the seal.

● Small Installation Area

S11-M series transformer tank uses the corrugated plate radiator. When the oil temperature changes, the corrugated plate will proceed thermal expansion, which can replace the role of the oil conservator. the corrugated plate tank has beautiful appearance, less occupied area.
