S11-M,S11 transformer

The serial transformers are in conformity with National Stardards G1094.1-5 Power Transformer and GB/T6451 Technical Specifications and Requirements for Three-Phase Oil-immersed Power Transformer.The serial transformers adopt a series of major improvement in fields of materials,technologies and structure,and have characteristics of high efficiency and low loss therefore it is a new product recommended by the state.Compared  with normal oil-immersed transformer,it gets rid of the oil reservoir ans oil pipes instead of fins of the corrugated oil tank as the cooling and beat radiation element.The corrugated oil tank is made by top quality cold-rolled thin steel plate on the special production line and fins can be changed as expansion /contraction of transformer oil thus to separate inside of the transformer with air,retard ageing of oil,avoid moistening of insulation elements and enhance reliability of operation.
