Product Description
Oil Immersed Series Transformer:
The S11-M series, a fully sealed oil immersed power transformer, is a remarkable innovation developed by Chaotai Power. This sophisticated piece of engineering boasts minimal loss, subdued noise levels, and outstanding efficiency. It's designed to deliver superior energy-saving performance and minimize environmental impact. Unlike standard oil immersed transformers, this model eliminates the need for an oil conservator thanks to a cleverly designed corrugated oil tank. The tank's elasticity compensates for oil volume fluctuations, allowing for automatic adjustments. This feature, coupled with complete isolation from air, significantly slows down oil deterioration and insulation aging, ensuring enhanced reliability and eliminating the need for maintenance during normal operations.
