The Yuanchen Hermetically Sealed Oil Immersed Transformer is an innovative re-engineering of traditional oil-immersed models. By removing the oil conservator and adopting a fully welded sealed tank structure, it eliminates oil oxidation and moisture ingress. Our transformer uses the natural elasticity of its corrugated tank walls to accommodate the thermal expansion and contraction of insulating oil, keeping the internal insulation dry and ensuring stable, consistent performance.
Our Advantages

FAQ
Q: What protection measures are in place if abnormal oil temperature rise occurs due to internal faults?
A: The Yuanchen Hermetically Sealed Oil Immersed Transformer tank is integrated with a pressure relay and over-temperature protection device. When the internal pressure or oil temperature exceeds the preset safety limits, the protection system will be activated immediately, triggering an alarm signal or tripping the circuit breaker to ensure equipment and system safety.
Q: What is the design service life of this transformer?
A: Under rated load and normal environmental operating conditions, the transformer has a design service life of no less than 30 years. Thanks to the ultra-slow aging rate of the insulation system, the actual service life is often much longer than the design standard.
