Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer, exclusively crafted by Zhejiang Chaotai Complete Equipment Co., Ltd. This innovative transformer boasts exceptional features such as low loss, minimal noise, and remarkable efficiency. Its design is intended to deliver substantial energy savings while significantly reducing pollution. In contrast to conventional oil immersed transformers, this fully sealed marvel eliminates the oil conservator. The transformer adapts to changes in oil volume through the flexible corrugated sheet within the oil tank, ensuring automatic adjustments and compensation. Ingeniously isolated from air exposure, it effectively prevents oil degradation and insulation aging, enhancing operational reliability and eliminating the need for maintenance during regular use.
