Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer, a marvel designed by Chaotai Power that stands out with its remarkable low loss, minimal noise, and exceptional efficiency. These features together create a powerhouse that not only conserves energy but also reduces environmental impact. Unlike the ordinary oil immersed transformers, our fully sealed design eliminates the need for an oil conservator. The transformer ingeniously adjusts and compensates for oil volume changes through the elasticity of the corrugated oil tank's sheet, ensuring a seamless operation that’s immune to air exposure. This innovative feature helps in slowing down oil deterioration and insulation aging, significantly boosting operational reliability while eliminating the need for maintenance during regular operations.

Our fully sealed oil immersed power transformer, crafted by Chaotai Power, ensures reduced loss, minimal noise, and outstanding efficiency, delivering a promise of energy conservation and pollution reduction.
In contrast to conventional models, our fully sealed transformer does away with the oil conservator. It intelligently adjusts oil volume changes via the corrugated oil tank's elasticity, shielding the system from air exposure. This protection mitigates oil deterioration and insulation aging, significantly enhancing operational reliability, negating the need for maintenance during standard operations.
