Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer by Zhejiang Chaotai Complete Equipment Co., Ltd. This innovative transformer boasts low loss and low noise characteristics, providing exceptional energy efficiency that not only saves energy but also minimizes pollution. Unlike traditional oil-immersed transformers, our fully sealed variant eliminates the need for an oil conservator. The oil volume fluctuates seamlessly through the elasticity of the corrugated oil tank, ensuring the transformer stays isolated from air exposure. This design significantly curtails oil degradation and insulation aging, thereby enhancing operational reliability and eliminating regular maintenance requirements.
