10.5kv Oil Immersed Power Transformer


S11-M Three Phase Transformer

Product Description

1.Product Description


Best quality S11-M power distribution transformer price

The fully sealed transformer is fully oil-immersed. This kind of oil-immersed transformer with the corrugated oil tank shell has been widely used in various power distribution equipments due to its own elasticity to accommodate oil expansion.


2.Product application:

S11-M series fully sealed oil-immersed distribution transformers comply with IEC standards. Its core is made of high quality cold rolled silicon wafer and full diagonal non perforated structure, and its coil is made of high quality oxygen free copper. Corrugated plate or expansion radiator tank.
Because there is no need for oil maintenance device, the height of the transformer is reduced. Because the transformer oil does not contract with the air, the aging of the oil is delayed, so as to prolong the service life of the transformer.
This product is widely used in urban power grid transformation, residential areas, factories, high-rise buildings, mining plants, hotels, shopping malls, airports, railways, oil fields, docks, highways and other outdoor places.
3.Product Features:

(1) Environmental protection transformer with small no-load loss, small no-load current and small noise;
(2) No oil storage box, saving space;
(3) Overall sealing, vacuum filling oil, high insulation stability;
(4) The corrugations on the oil tank are used as the heat dissipation components. The corrugations can expand or contract with the change of the amount of oil
(5) Fully sealed structure, maintenance free;
(6) Equipped with oil level gauge to ensure safe operation.

4.Applicable Environment:


(1) High ambient temperature: +40℃
(2) Low ambient temperature: -25℃
(3) Altitude: <1000m
(4) Monthly average relative humidity: 90% (20℃)
(5) Installation location: Install in a place where there is no fire, explosion hazard, serious pollution, chemical corrosion and severe vibration, indoors or outdoors.
