Product Description
Oil Immersed Series Transformer:
The S11-M series, a marvel in fully sealed oil immersed power transformers, is expertly crafted by Chaotai Power. It boasts remarkable attributes such as low loss, minimal noise, and exceptional efficiency, ensuring an outstanding energy-saving performance while curbing pollution. Unlike conventional oil-immersed transformers, this advanced model eliminates the oil conservator. Instead, it employs a cutting-edge system where the oil volume is automatically adjusted and compensated through the elasticity of the corrugated oil tank's corrugated sheet. This design significantly reduces exposure to air, effectively slowing down oil deterioration and insulation aging, thus enhancing operational reliability and minimizing the need for maintenance during standard operations.

Chaotai Power's fully sealed oil-immersed transformers are engineered for excellence with features of low loss, quiet operation, and high efficiency, promising substantial energy savings and reduced environmental impact.
This advanced fully sealed transformer design eliminates the need for an oil conservator. It integrates a self-adjusting mechanism for oil volume via the corrugated oil tank's sheet elasticity. This cutting-edge feature keeps the transformer isolated from air, slowing oil degradation and insulation aging, improving operational reliability, and eliminating the need for routine maintenance.
