Distribution Hermetic Transformers With Nitrogen Cushion

Distribution Hermetic Transformers With Nitrogen Cushion

Overview

Three-phase oil filled distribution hermetic transformers for utility, industrial, and commercial applications, are used to step down three-phase high voltage to low voltage for energy distribution. These transformers have a gas space filled with nitrogen gas above the oil. Transformers can be used for indoor or outdoor applications and can be provided with off-load and on-load tap changers.
