Product Description
Oil Immersed Series Transformers:
Introducing the S11-M Series, a fully sealed oil immersed power transformer crafted by Zhejiang Chaotai Complete Equipment Co., Ltd. This transformer showcases remarkable features such as minimal loss, ultra-quiet operation, and outstanding efficiency. These attributes contribute to significant energy savings and pollution reduction that are unparalleled. Unlike conventional oil immersed transformers, this advanced model eliminates the need for an oil conservator. It cleverly uses the flexibility of a corrugated sheet within its oil tank to self-adjust oil volume variations. By being isolated from the atmosphere, the transformer notably curtails oil degradation and insulation aging, thereby boosting operational reliability and significantly reducing the necessity for routine maintenance.
