Product Description

Features and Benefits

 

• High Efficiency: The design of the oil immersed series transformer is optimized for high efficiency, resulting in lower energy consumption and reduced operating costs.
• Reliable Operation: The use of high-quality materials and advanced manufacturing processes ensures reliable operation of the transformer even in harsh environmental conditions.
• Long Service Life: The insulating oil provides excellent protection to the windings and core, extending the service life of the transformer.
• Easy Maintenance: The transformer is designed for easy maintenance, with accessible components and simple inspection procedures.

We are pleased to present our latest energy efficient power transformer - the oil immersed transformer. Developed and produced by our company,this fully sealed transformer uses cutting-edge technology to provide superior performance and numerous benefits to our customers.

One of the main advantages of our range of oil-immersed transformers is low loss and high efficiency. Through careful engineering and design, we have significantly reduced energy waste during the renovation process. This results in significant savings in power consumption, making our transformers ideal for energy efficient customers. By choosing our energy efficient transformers, businesses can not only reduce their carbon footprint, but also achieve significant cost savings in the long run.

The rated voltage can be customized as customers' requirements.
The fully sealed oil-immersed power transformer developed by ZONCHENG 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.

Product Details
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.
