Product Description
Oil Immersed Series Transformer:
The S11-M series, a groundbreaking fully sealed oil immersed power transformer, is a testament to Chaotai Power's commitment to excellence. This transformer boasts remarkable advantages including low loss, whisper-quiet operation, and unparalleled efficiency. Designed for optimal energy savings, it significantly curtails pollution. Unlike conventional oil immersed transformers, this fully sealed marvel eliminates the need for an oil conservator. The ingenious design automatically adjusts and compensates oil volume changes via the elasticity of the corrugated sheet in the oil tank, ensuring isolation from the air. This feature not only prevents and decelerates oil deterioration and insulation aging but also enhances operational reliability, eliminating the need for maintenance during normal operation.
