Product Advantages
- Multi-Capacity ONAN/ONAF Cooling Structure
Rated at 10/11.2/12.5/14 MVA, this transformer uses radiator banks and cooling fan assemblies to support ONAN/ONAF operation. It helps customers cover normal load and fan-assisted peak demand with one unit, reducing the need for immediate transformer replacement when load requirements increase.
