Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer by Chaotai Power. This masterpiece is engineered to deliver unparalleled advantages such as low loss, minimal noise, and exceptional efficiency. Its energy-saving effects are phenomenal, significantly reducing pollution. Unlike ordinary oil immersed transformers, our fully sealed design eliminates the need for an oil conservator. The oil volume variations are smoothly managed by the elasticity of the tank's corrugated sheets, ensuring a seamless operation. Moreover, the transformer's complete isolation from air prevents oil degradation and insulation aging, thereby boosting operational reliability and reducing maintenance requirements.
