Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a cutting-edge oil-immersed power transformer by Zhejiang Chaotai Complete Equipment Co., Ltd. Renowned for its remarkable attributes of low loss, minimal noise, and superior efficiency, this transformer heralds a new era of energy conservation and pollution reduction. Unlike conventional transformers, this fully sealed marvel eliminates the need for an oil conservator.
