10KV, S9-M S10-M S11-M Series 3 phase omni-sealed transformer with no-load tap changer

Product description

　　Our S9-M, S10-M, S11-M series 3-phase oil-immersed transformer is conform to the standard of IEC , GB1094 "Power Transformer" and GB/T6451-2008 "Technical Parameters and Requirements of Three-phase Oil-immersed Power Transformer". The iron core is made of quality cold-rolled silicon steel sheet, and in full-miter non-puncture structure. The coil is made of quality oxygen-free copper, featuring good outlook and safe running. The products are widely used in power transmission and distribution of industrial and agricultural power networks.

Feature

　　1.The tank adopts corrugated plate or Expansion type radiator without oil conservator ，thus the height of the transformer is reduced.

　　2. The transformer oil and insulators are separated from the air and water outside, and thus the aging of transformer oil and insulators is slowed down,The oil tank is sealed with high performance oil resistant rubber which can be used for 30 years without the on-site core-suspension inspection, thus reducing operation and maintenance cost. It is good for maintenance at inconvenient places. The no-load loss of S10-M type is 20% lower than S9-M type, and S11-M type is 30% lower than S9-M type. High reliability, advanced level of performances,reasonable economical indicators.
