oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding
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.
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.
1.Power Capacity: 315KVA (Our co.can make 30KVA Upto 20 MVA)
2.Voltage Level: 22/0.38 KV (can be made as buyers requirements)
3.Type of Voltage Regulation: Off-circuit or On-Ioad
4.Tapping Range: ±2x2.5 % (can be made as buyers requirements)
5.Frequency: 50Hz or 60Hz
7.Connection Symbol: Dyn11
8.Short- circuit Impedance: Standard Impedance
9.Altiude is not exceeding 1000m,ambient temperature not exceeding 40OC. If it can't meet such conditions,we will modulate parameters in accordance with standard.
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.
1. The maximum ambient air temperature shall not exceed 40 ℃, and the minimum shall not below - 25 ℃;
2. The altitude shall not exceed 1000m. If special customized transformers and low-voltage components are used, the altitude can reach 4000m;
3. The vertical inclination is no more than 5 °, and no violent vibration and impact;
4. The air humidity is not more than 90% (+ 25 ℃);
5. No gas and conductive dust that will seriously affect the insulation of transformer, no explosion hazard and corrosion of electrical components;
6. Outdoor wind speed shall not exceed 35m / s.
7. If service conditions beyond the above, specially customized product is available.
