oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding
Product Features:
The transformer is a transformer whose interior is isolated from the air surrounding, so the transformer oil can not absorb the outer moisture and the oxygen since the change of transformer's volume could be fixed with the flexibility of corrugated tank structure. Then the aging speed of insulated material will be decreased. Before running the machine, the work of core suspension checkup is not necessary. Clients could also be free from the later maintenance and reparation. The reliability of products is visibly upgraded. Products is designed with PCCAD, the characters are conformed to IEC 60076 and GB 1094, and passed qualification ISO 9001.
Advantage:
The body adopts a new type of insulation structure to improve the
ability to withstand short-circuits;
Spiral coil with longitudinal oil passage has a better internal
heat dissipation;
High efficiency, low loss, can save a lot of power and operating
costs;
The surface of the corrugated oil tank is coated with three
anti-paint after oil removal, rust removal, and phosphating.
It is suitable to use in metallurgy, petrochemical, and mining environments.
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.
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.
·Service conditions
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.
Workshop
ATTENTION:
1.The payment term: We accept TT,30% deposit and 70% balance
against copy of BL.
2.The delivery time: Usually it will take about 15-20 days.
3.The standard of package: Usually use strong plywood case for
protection.
4.The material of transformer: We have two types, one is with
copper and another one is with aluminum. It depends on your
requirement. In fact, those two have difference if normal work
well. Only except the long life. Copper is better and also higher
price.
5.The logo: If you have good quantity, it absolute no problem to do
OEM.
6.Our market: our products are popular in Indonesia, Philippines,
Russia, USA, Middle East and so on. Some of them are our regular
customers and some of them are developing. We hope you can join us
and make mutual benefit from our cooperation..
7.Warranty: in 12 month since BL date.
