Product Description
Oil Immersed Series Transformer:
The S11-M series, a fully sealed oil-immersed power transformer, is a cutting-edge product developed and produced by Chaotai Power. Boasting low loss, minimal noise, and high efficiency, this transformer is a beacon of energy-saving prowess, significantly reducing environmental pollution. Unlike traditional oil-immersed transformers, this fully sealed marvel eliminates the need for an oil conservator. Instead, it utilizes the adaptive elasticity of the corrugated sheets within the corrugated oil tank to automatically adjust and compensate for oil volume changes. By being completely isolated from the air, it mitigates oil deterioration and insulation aging, thereby enhancing operational reliability and eliminating the need for regular maintenance during standard operation.
