S9-M S10-M S11-M S11-MR distribution transformer
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. Its core is made of quality cold-rolled silicon sheet and is of a full-miter non-puncture structure and its coil is made of quality oxygen-free copper. It is artistic in appearance and safe in running and is widely used in transmission and distribution of industrial and agricultural networks.
Main Functions And Features
It adopts radiator oil tank of corm gated sheet type or expansion type As it doesn't need oil conservator, the height of transformer is reduced, and as the transformer oil doesn't contract with air, the oil ageing is retarded, thus prolonging the sen/ice life of transformer The no-load loss of Model S1Q-M Is 20% lower than that of Model S9-M, and S11-M is 30% lower than S9-M. The transformers are high in reliability, advanced in performances and rational in economical indexes. The oil tank is diversified in types and looks artistic and elegant.
Oil immersed transformers of 1000kVA and above shall be equipped with outdoor signal thermometers and connected to remote signals. Oil immersed transformers of 800kVA and above shall be equipped with gas relays and pressure protection devices, and gas immersed transformers below 800kVA may be negotiated with the manufacturer according to the service requirements. Dry type transformer shall be equipped with temperature measuring device, generally 630kVA and above.
1. Non-closed oil-immersed transformer: it mainly has S9, S11 and other series of products, which are widely used in industrial and mining enterprises, agricultural and civil buildings.
2. Closed oil-immersed transformer: it mainly has S9, S9-M, S11-M and other series of products, which are mostly used in places with more oil pollution and more chemical substances in the petroleum and chemical industries.
3. Sealed oil-immersed transformer: it mainly has BS9, S9-, S10-, S11-MR, SH, SH12-M and other series of products, which can be used for power distribution in industrial and mining enterprises, agriculture, civil buildings and other places.
