Product Description
Oil Immersed Series Transformer:
Introducing the exceptional S11-M series fully sealed oil-immersed power transformer, meticulously engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This transformative piece of technology is a testament to our commitment to innovation, offering unparalleled qualities such as low energy loss, reduced operational noise, and outstanding efficiency. It is the epitome of an energy-saving solution, dramatically lessening environmental pollution. Departing from conventional designs, this cutting-edge transformer eliminates the oil conservator. Its smart design allows for autonomous oil volume adjustment, thanks to the elasticity of the corrugated oil tank, ensuring a hermetic seal against air exposure. This groundbreaking feature not only preserves oil integrity and slows insulation aging but also significantly heightens operational reliability, eradicating the need for routine maintenance under standard conditions.
