Product Description
5000kVA 33kv/13.8kV Three Phase Oil Immersed Substation Power Transformer ANSI IEEE Standards
This 5 MVA 33kV/13.8kV oil-immersed power transformer is designed for medium-voltage substation and industrial distribution applications where stable voltage conversion and reliable load handling are required. It is rated for 5,000 kVA continuous operation and can operate up to 5,600 kVA under short-time overload conditions based on its thermal design margin. It is commonly applied in utility substations, industrial power systems, and grid interconnection projects where load fluctuation and peak demand operation need to be accommodated within defined thermal limits.
