Proven reliability: 10-year zero-failure record on South China Sea oil rigs.
Cost-effective
They allow for cheap installation and maintenance and the need for change is minimal since the transformer is robust.
Reliable and durable
The transformers can sustain a variety of environmental conditions with low rates of failure which makes them dependable for long periods.
High efficiency
Less energy losses, enable oil immersed transformers to perform excellently under heavy loads.
Efficient cooling
Oil absorbs dissolves and radiates heat efficiently to avoid overheating of the transformer as well as consistent transformer operation at high loads.
Enhanced insulation and safety
The oil acts as an insulating cover for the windings reducing the risk of electrical discharges and increasing the life span of the transformer.
Versatile applications
Integrated factory strength to support all kinds of tape customization,with paper base,cloth base,glue,coating all raw material production capacity

Precautions for Using Oil-immersed Transformer
To maximize performance while avoiding damage, follow these basic loading practices:
Analyze load profile
Ensure the load never exceeds the transformer’s rated capacity to prevent overheating or premature wear.
Consider environmental factors
Adjust operating parameters for ambient temperature and altitude to maintain optimal performance.
Schedule routine maintenance
Conduct regular checks, including oil testing and part replacements, for long-term efficiency and reliability.
Regularly monitor oil levels
Maintain consistent levels to preserve cooling and insulating performance. Overfilled tanks risk pressure buildup, while underfilled tanks reduce efficiency.
Use load tap changers
Tap changers help adjust voltage output to meet varying load demands, ensuring stability and efficiency.
