Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a fully sealed oil-immersed power transformer crafted with precision by Chaotai Power. This remarkable transformer boasts outstanding features such as low loss, minimal noise, and exceptional efficiency, making it a superior choice for energy conservation and pollution reduction. Unlike conventional oil-immersed transformers, the fully sealed design eliminates the need for an oil conservator. The innovative corrugated oil tank adjusts and compensates for oil volume changes through the elasticity of its corrugated sheet. This design isolates the transformer from air, effectively preventing oil deterioration and insulation aging, thus significantly enhancing operational reliability and negating the need for regular maintenance.
