Station Service Oil-Immersed Transformer

The station service oil-immersed transformer is positioned for internal auxiliary supply in substations, supporting lighting, maintenance, ventilation, control, and other operational service loads. Its engineering focus is steady performance under continuous energized duty, delivering reliable AC power to critical secondary equipment such as protection and control panels as well as switchgear spring-charging motors.

The series is also suitable as the AC input source for DC-system charging sections, helping maintain battery charging continuity and stable station DC bus operation. To match utility expectations on reliability, short-duration overload tolerance, and maintenance efficiency, this product line typically adopts mature insulation design and standardized testing practice for safe operation and controlled lifecycle cost.
