Product Description
Oil Immersed Series Transformer:
The S11-M series, meticulously engineered and crafted by Zhejiang Chaotai Complete Equipment Co., Ltd., revolutionizes the world of power transformers. This fully sealed, oil-immersed power transformer boasts unparalleled advantages such as low loss, minimal noise, and outstanding efficiency. These features not only contribute to exceptional energy-saving capabilities but also play a vital role in minimizing environmental pollution. Unlike traditional counterparts, this cutting-edge transformer realizes the elimination of the oil conservator. The clever design of the corrugated oil tank allows the oil volume to be automatically adjusted and compensated through the elasticity of its corrugated sheet. This innovative isolation from the air significantly slows down the deterioration of oil and insulation aging, ensuring robust operational reliability and virtually maintenance-free operation under normal conditions.
