S11 type sealed oil-immersed power transformer. Products: power transformers as the most widely used power facilities, the number of a wide range of great significance for energy conservation. S11 type sealed oil-immersed power transformers and distribution equipment is the main selection of products, energy-saving effect is remarkable. Our distribution transformers implications for the performance of the code: S7 type in the above, no-load loss is reduced by about 10 percent each, code-named "7" is added to the figure "1." From S7 to S9-based development model, the load loss decreases more, an average of 25 percent, and later, because there is no groundbreaking new materials, new technologies and new technology, distribution transformer load loss dropped more difficult, so the performance level code load loss is usually reduced to the standard. To 400kVA products, for example, S7 type load loss 920W, S11-type load loss 570W, a decrease of 38%. Currently, the mainstream S11 type distribution transformers generally used stacked core power transformer. A fully sealed oil-filled, non-conservator, corrugated sheet cabinet structure, the transformer due to changes caused by changes in temperature and load oil temperature and volume, to be made entirely of corrugated tank regulator, the load loss 25% lower than the S9, Short circuit resistant anti-lightning surge capability, significant energy savings and reduce the dimensions of the transformer. S11 type transformer with high permeability oriented silicon steel production, the film thickness of 0.27-0.30mm, units of iron loss for 1w / kg, while the new S9 model for ordinary silicon steel sheet thickness 0.30-0.35mm, iron loss of 1.20 units -1.55w / kg. I produced the S11 type distribution transformers Shanghai Baosteel all use of 30P series high permeability oriented silicon steel, using the foil around the coils and new insulation materials and processes, products, high temperature, shock, fully sealed design ensures the transformer stable oil quality, to extend the maintenance cycle, while the overall tank radiator composed by corrugated sheets using phosphate and multi-rust coating production process, with good weather performance. 2.

Features: 10kv class S11 type sealed power transformer capacity range 30kVA ~ 2500kVA, at 10KV, 50HZ transmission and distribution systems, and can be widely used in high-rise buildings, commercial centers, subways, airports, railway stations, industrial and mining, drilling platforms, oil platform, especially for flammable, explosive and other high fire safety requirements and the harsh environment of places. Also available in residential, commercial street, industrial and mining enterprises and rural power and lighting purposes. Long service life, maintenance-free operation. Sealed boxes along with the transformer cover bolts or welded structure coupling, oil and air cut off contact, not damp insulation, insulation aging greatly reduce speed and improve the service life. Compact design, low operating noise. Due to the introduction of new materials and new technology to reduce noise, no conservator height lower than similar products. In the normal lifetime without an oil change, to improve the safety and reliability of the network operation. Corrugated tank is small, beautiful appearance. S11-type power transformer tank using corrugated sheet cooling, when the oil temperature, changes in the volume of oil by the elastic expansion corrugated sheets shrink to adjust compensation. Hanging core and oil-free testing. Transformer package, using vacuum filtration oiling process to completely remove the moisture in the transformer oil. After sealing the inside of the transformer is not in contact with the air, effectively prevent oxygen and moisture into the insulation performance degradation caused by a transformer.
