Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a fully sealed oil-immersed power transformer crafted by Chaotai Power. This cutting-edge transformer stands out with its remarkable features: low loss, minimal noise, and exceptional efficiency. Its superior energy-saving capabilities significantly reduce pollution. Unlike traditional oil-immersed transformers, this advanced model eliminates the need for an oil conservator. Instead, it innovatively adjusts oil volume changes through the elasticity of the corrugated oil tank sheets. By being completely isolated from the air, it greatly reduces oil deterioration and insulation aging, ensuring enhanced operational reliability and eliminating the need for maintenance during normal operation.

The fully sealed oil-immersed power transformer by Chaotai Power is engineered for remarkable performance, boasting low loss, low noise, and high efficiency for an outstanding energy-saving impact while minimizing environmental pollution.
Distinguished from ordinary oil-immersed transformers, this fully sealed model ingeniously removes the oil conservator. It automatically adapts to oil volume changes using the corrugated oil tank's elasticity, effectively isolating it from air exposure. This design significantly curtails oil deterioration and insulation aging, bolstering operational reliability and eliminating routine maintenance.
