Project Background
The project required a single-phase distribution transformer with higher-than-standard capacity for pole-mounted applications.
Due to the transformer’s weight and rating, a platform-supported installation design was selected to ensure safe mounting and long-term mechanical stability.
The transformer was required to operate under outdoor conditions and align with the existing medium-voltage distribution parameters, including voltage level, impedance, and tapping configuration.

Engineering Considerations
The transformer was designed with an ONAN cooling system and a sealed oil-immersed structure to support continuous outdoor operation.
Electrical design considerations included impedance control, tapping range configuration, and load loss optimization, ensuring compatibility with the existing distribution network.
A platform-type structure was incorporated to support the transformer’s rated capacity and total weight while maintaining compliance with applicable installation practices.
