oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding 
The capacity range of 10kV class S11 full seal power transformer is 30kva-2500kva. In 10kV, 50Hz power transmission and distribution system, it can be widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling platforms, especially in places with high fire protection requirements such as inflammables and explosives, and in places with poor environment. It can also be used for power and lighting in residential areas, commercial streets and rural areas.
Advantages:
S11 type fully sealed oil immersed transformer is the main type selection product of current distribution equipment, with remarkable energy saving effect. The S11 distribution transformer produced by our company uses 30p series high conductivity oriented silicon steel produced by well-known enterprises, and adopts new insulating materials and processes. The products are resistant to high temperature and impact. The integral mailbox composed of corrugated radiator is produced by phosphating and multi-layer antirust spraying technology, which has good weather resistance.
High-quality material
a. The three- phase oil-immersed Power Transformer applies new type insulating structure.
b. The iron core is made of high-quality cold-rolled silicon-steel plate 27ZH10.
c. All fasteners have been processed with special trearment to prevent them from loosening.
Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won’t split or move even under the influence of short circuit.
Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
High-quality rubber sealing material, which can prevent the transformers form aging or leakage.
Reliale structure
a. Spiral loops with longitudinal oil path to produce a better interior cooling effect;
b.New suspending structure and instrument positioning frames to guarantee the long distance transportation.
