Product Description
Oil Immersed Series Transformer Overview:
Introducing the S11-M series, a fully sealed oil-immersed power transformer by Chaotai Power, designed for exceptional efficiency in energy distribution. This innovation boasts low loss and noise levels, amplifying energy savings while minimizing environmental impact. Distinct from conventional models, the fully sealed design eliminates the need for an oil conservator. The oil volume automatically adjusts, thanks to the flexible corrugated sheet, maintaining isolation from air. This ensures prolonged oil quality, reduces insulation wear, maximizes operational reliability, and significantly cuts down on regular maintenance requirements.
