Product Introduction
Oil-immersed transformer is a transformer device that uses oil cooling to reduce the temperature of the transformer. Unlike dry-type transformers, the main body of an oil-immersed transformer is installed in a welded steel tank filled with insulating oil. When the oil-immersed transformer is in operation, the heat of the coil and core is first converted into insulating oil and then into cooling medium. According to the capacity, it can be divided into immersed natural cooling transformer and immersed forced air cooling transformer.
Features
- Advantage
Strong heat dissipation performance, suitable for outdoor and harsh environments.
The winding is immersed in insulating oil to improve insulation performance and protect internal components.
The insulating oil of oil-immersed transformers has high heat capacity and dielectric strength.
The vacuum drying and oil filtering and oil filling process are used to reduce moisture. - High efficiency
Oil-immersed transformers have high working efficiency. Since the insulating oil can provide a good cooling effect, the temperature of the winding inside the transformer is effectively controlled, thereby improving the operating efficiency of the transformer. In addition, the oil-immersed transformer also has low losses, can achieve high energy conversion efficiency, and reduce energy waste. - Reliability
Oil-immersed transformers perform well in terms of reliability. The insulating oil plays a good insulating role inside the transformer, which can effectively isolate the windings and prevent faults such as arcing and discharge. At the same time, the insulating oil can also stabilize the temperature and prevent the transformer from overheating, thereby increasing the life of the equipment. In addition, the noise and vibration levels of the oil-immersed transformer are relatively low, which helps to reduce the mechanical stress of the equipment and improve the reliability and stability of the equipment. - Safety
Oil-immersed transformers also have advantages in safety. Due to the good insulation properties of the insulating oil, electric shock accidents can be prevented to a certain extent. At the same time, oil-immersed transformers are usually equipped with complete safety protection measures, such as overload protection, short-circuit protection, etc., to ensure the safe operation of the equipment.

Production Process
FAQ
Q: How safe are oil-immersed transformers, particularly regarding fire risk?
A: Modern designs ensure safety. They use fire-resistant insulating oils (e.g., mineral oil meeting IEC 60296 or biodegradable ester fluids) within robust, sealed tanks. Pressure relief devices activate safely during internal faults, and designs comply with strict international safety standards (IEC).
Q: Is oil leakage a concern, and what maintenance is required?
A: Our transformers feature fully sealed construction (e.g., corrugated tanks or welded conservator tanks), minimizing leakage risk. High-quality insulating oil maintains stable chemical properties under normal operation. Maintenance primarily involves periodic oil sampling/testing and condition monitoring, reducing long-term upkeep.
Q: How are oil-immersed transformers protected during shipping?
A: We provide export-grade packaging: robust wooden crates, internal bracing/shock absorption, oil level monitoring, pressure gauge protection, and desiccants. Detailed transport and handling instructions ensure secure delivery.
Q: Are special foundations or space requirements needed for installation?
A: A level, robust foundation is essential to support the weight and minimize vibration. We supply precise dimensional drawings, foundation specifications, required clearances (safety zones), and ventilation guidelines for proper site preparation and installation.
