S11-MR Series Full-sealed Transformer          •Introduction To Products                 The performances of model S9-M, S10-M, S11-M, S11-MR  10kV series full-sealed oil-immersed distribution transformers conform to standards GB1094 "Power transformer" and GB/T6451-2008 "Technical Parameters and Requirements of three-phase Oil-immersed Power transformer".   01) The core is made of quality cold-rolled silicon sheet;  02) Is of a full-miter non-puncture structure;  03) its coil is made of quality oxygen-free copper;   04) The core is clamped with sheet-formed frame structure; 05) the low-voltage coil is of a foil winding type so as to render a low loss and a high short-circuit withstand; 06) It has advanced and rational structure and its overall performances reach international advanced level.   •Main Function And Features  10kV Spiral core transformer 50 kva transformer 01) It adopts radiator oil tank of corrugated sheet type or expansion type; 02) As it doesn’t need oil conservator, the height of transformer is reduced; 03) The transformer oil doesn’t contact with air , the oil ageing is retarded, thus prolonging the service life of transformer; 04) The no-load loss of Model S10-M is 20% lower than that of Model S9-M , and S11-M is 30% lower than S9-M; 05) Low loss, high reliability, High efficient transformer; 06) Low corrective force, Low excitation current, Good temperature stability; 07) Environmental protection; 08) The transformers are high in reliability , advanced in performance and rational in economical indexes; 09) The oil tank is diversified in types and looks artistic and elegant; 10) Oil box is sealed, free from maintenance. Box is sealed, free from maintenance.   •Application Range             Widely used in city network, petrochemical industry, metallurgy, textile, or the mines or companies where are under the condition of high humidity or with the difficulty in maintenance.   Main Technical parameters for 10kV level, S11-MR series  full-sealed spiral core transformer:
