oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding
Product Features:
Our company can produce a variety of oil-immersed transformers with a voltage rating of 35kV or less and a capacity of 12500kVA or less. The variety includes S9, S11 series and S13, S15 series of energy-saving products. The product is widely used in industrial and mining enterprises, agriculture, civil construction and other distribution sites as well as oil, chemical industry, more oil, more chemical substances in the places.
1. Good Economic Performance
The no-load loss for S11 series products decreased 10.3% averagely, no-load current decreased 22.4% based on S9 series.
2. Long Service Life
Transformer tank adopts hermetical structure, tank and tank cover can be connected by bolts or welded firmly, the transformer oil won’t contact with air, so that extend the service life effectively.
3. High Operation Reliability
Improve the relevant sealing parts for the tank, increase the reliability and advance the technical level to ensure the reliability of the seal.
4. Small Installation Area
S11-M series transformer tank uses the corrugated plate radiator. When the oil temperature changes, the corrugated plate will proceed thermal expansion, which can replace the role of the oil conservator. the corrugated plate tank has beautiful appearance, less occupied area.

Material
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.
