Factory Price 11KV Oil Immersed Power Supply Transformer to 400v

Product Description

oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding

Product Features:
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.

Advantage:
1, low no-load loss and low load loss;
2, low noise;
3, low voltage partial discharge;
4, high anti short-circuit capacity;
5, reliable performance, no oil leakage and no damages.

Compare with S9 series Transformer, S11-M series Transformer decrease 30% of no-load loss; decrease

70-85% of no-load current; decrease 10K of average temperature rising; double the service life; decrease

the noise of 2-4db; decrease 40 % of running cost.

Normal S11-M Series Transformer apply to the altitude below 1000m; the circumstance temperature between

-25ºC and +40ºC.

·Service conditions
