Product Description
Cutting-edge Oil Immersed Series Transformer:
The innovative S11-M series, a fully sealed oil immersed power transformer crafted by Chaotai Power, stands out with its remarkable advantages of low loss, minimal noise, and superior efficiency. This powerhouse not only promises excellent energy-saving effects but also significantly reduces pollution. Unlike standard oil immersed transformers, this advanced fully sealed variant has eliminated the need for an oil conservator. Ingeniously designed to automatically adjust and compensate oil volume changes through the elasticity of the corrugated oil tank's sheet, it ensures the transformer remains isolated from air exposure. This innovative feature helps in slowing down the deterioration of oil and insulation aging, thereby boosting operational reliability and eliminating the need for maintenance during normal operations.
