Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a state-of-the-art fully sealed oil immersed power transformer meticulously crafted by Zhejiang Chaotai Complete Equipment Co., Ltd. This innovative transformer boasts remarkable features such as low loss, minimal noise, and superior efficiency, paving the way for exceptional energy-saving capabilities while minimizing environmental impact. Unlike conventional oil immersed transformers, our fully sealed design eliminates the need for an oil conservator. Ingeniously, it self-regulates oil volume fluctuations through the elasticity of the corrugated oil tank's sheets. This transformer remains isolated from the air, effectively mitigating oil deterioration and insulation aging. Furthermore, its enhanced reliability ensures maintenance-free operation, setting a new standard for operational excellence.
