Product Description
Oil Immersed Series Transformer:
Zhejiang Chaotai Complete Equipment Co., Ltd. proudly introduces the S11-M series, an exceptional fully sealed oil immersed power transformer. This remarkable transformer is engineered to deliver superior energy efficiency with low loss and minimal noise, ensuring an impressive energy-saving performance while significantly reducing pollution. Unlike conventional transformers, the fully sealed design eliminates the need for an oil conservator. Instead, the oil volume is seamlessly adjusted and compensated by the corrugated oil tank's elasticity, isolating the transformer from the air. This ingenious feature helps to prevent oil degradation and insulation aging, greatly enhancing operational reliability and eliminating the need for maintenance under standard operational conditions.

The fully sealed oil immersed power transformer by Chaotai Power exemplifies innovation with its low loss, low noise, and high efficiency, ensuring remarkable energy-saving benefits while minimizing environmental impact.
In contrast to traditional oil immersed transformers, this fully sealed design dispenses with the oil conservator. The unique elasticity of the corrugated oil tank automatically adjusts the oil volume, protecting the transformer from air exposure. This innovative approach decelerates oil and insulation aging, boosts operational reliability, and negates the need for maintenance during regular use.
