Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformers, innovatively designed and manufactured by Chaotai Power, boast an array of benefits including minimal energy loss, reduced noise levels, and remarkable efficiency. These remarkable features not only promise substantial energy savings but also contribute to lower environmental pollution. Unlike typical oil-immersed transformers, this advanced version eliminates the need for an oil conservator, ingeniously balancing oil volume through the adaptive flexibility of its corrugated oil tank's sheet. This design ensures isolation from air, significantly delaying oil degradation and insulation wear, thereby boosting operational reliability and negating the need for regular maintenance.
