Discussion on Oil Immersed Transformer Manufacturers

Oil Distribution transformers are one of the important equipment in the power supply and distribution systems of industrial and mining enterprises and civil buildings. They reduce the network voltage of 10 (6) kV or 35kV to the 230/400V bus voltage used by users. This product is suitable for AC 50 (60) Hz, three-phase maximum Nameplate capacity 2500kVA (single-phase maximum Nameplate capacity 833kVA, single-phase transformer is generally not recommended), and can be used indoors (outdoors). When the capacity is 315kVA or less, it can be installed on the pole. The ambient temperature is not higher than 40 ℃, not lower than -25 ℃, the maximum daily average temperature is 30 ℃, the maximum annual average temperature is 20 ℃, and the relative humidity is not more than 90% (ambient temperature is 25 ℃), The altitude shall not exceed 1000m. If it does not comply with the above usage conditions, appropriate quota adjustments should be made in accordance with the relevant provisions of GB6450-86.

The biggest characteristic of the "oil transformer" we have seen is that it is very "strong". Although it experiences wind, rain, cold, frost, and scorching heat outside, it is not afraid at all, and still steadily serves everyone's normal electricity consumption. This has its own structure and characteristics.

They have a wide range of uses. It can be used in various power distribution locations, such as rural, urban, commercial supporting facilities, scenic spots, etc., and can also be used in large complete sets of equipment, such as box substations, European style box transformers, and buried box transformers of Zhongmeng Electric.

Structure and characteristics of S11 oil immersed transformer

The fully sealed S11 oil immersed transformer has the characteristics of high operating efficiency and low losses. Its no-load loss decreases by 30%, and its load loss decreases by an average of about 22%.

The oil tank of the oil immersed transformer is composed of corrugated walls, and its surface is sprayed with dust and the paint film is firm. Beautiful, practical, and durable, its corrugated heat dissipation fins not only have the effect of cooling, but also have the function of "breathing". The elasticity of the corrugated heat dissipation fins can compensate for the changes in transformer oil volume caused by temperature rise and fall. Therefore, the S11 oil immersed transformer does not require an oil storage tank, reducing the overall volume.

In terms of windings. Using corrugated oil ducts, non immersion paint process, tight band binding, high-voltage winding with taps that meet the requirements of tap voltage, led to the tap switch, which is installed on the box cover and needs to cut off the power before changing the tap voltage.

S11 Oil immersed transformer price

Compared to dry type transformers, the price of oil transformers is relatively cheap. Before inquiring with the power transformer manufacturer, all parameters required for the transformer, such as model, capacity, all copper or all aluminum, and what location to use, should be prepared so that the manufacturer can quickly quote. The price of S11 oil immersed transformer with 800kVA all copper is around 45000, with some manufacturers offering higher prices and others offering lower prices.
