Product Description
Oil Immersed Series Transformer:
Introducing the state-of-the-art S11-M Series Fully Sealed Oil Immersed Power Transformer by Zhejiang Chaotai Complete Equipment Co., Ltd. This cutting-edge transformer is engineered to deliver unparalleled performance with its outstanding features of low loss, low noise, and high efficiency. Its design ensures excellent energy-saving capabilities and significantly reduces pollution. Unlike typical oil-immersed transformers, this innovative transformer eliminates the need for an oil conservator, with the oil volume changes adeptly managed through the resilient corrugated sheet of its oil tank. Completely isolated from the air, this transformer minimizes oil deterioration and insulation aging, significantly boosting operational reliability while ensuring maintenance-free performance during standard operation.
