Product Description

Product Description

The fully sealed oil-immersed power transformer  has the advantage of low loss, low noise and high efficiency, which can achieve good energy-saving effect and reduce pollution. Compared with the ordinary oil immersed transformer, the fully sealed transformer cancels the oil conservator, and the change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank. The transformer is isolated from the air, so as to prevent and slow down the deterioration of oil and insulation aging, enhance the operation reliability, and avoid maintenance in normal operation.

Mainly Components:
The mainly parts of this transformer include Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is used to soak the windings by placing it in.
2. Comply with IEC standards with CE/ISO certificates
3. be easily contacted & enlarge throughout loading so that the temperature of the oil can be increased and decrease.
4. Buchholz relay is used when a conservator tank is used. Because it indicates errors like loss of oil once it goes low, improper flow of oil between the tank & transformer.
5. Breather Unit includes silica gel that absorbs moisture in the oil. It changes its color from blue color to pink color it is not capable to absorb moisture in the oil.
6. The oil indicator indicates the level of the oil within the conservatory unit.
7. The temperature detector monitors the temperature of the oil. If the temperature of the oil increases to a certain level then the transformer will be disconnected from the service.
8. Pressure relief device decreases the pressure within the transformer to avoid an explosion of the transformer.
9. Thermal relay is used as an indicator for the temperature of the winding
10. Full galvanized coating   no rust
11. The bushing is used to connect the internal windings of the transformer with the help of an exterior electrical network.
The rated voltage can be customized as customers' requirements.
