The 500 kVA oil-immersed pad-mounted distribution transformer is designed for medium- and low-voltage power distribution in utility and commercial networks where compact installation, outdoor operation, and reliable performance are required.

This transformer features a 4.16 kV primary voltage and 480 V secondary voltage, providing stable three-phase power for industrial facilities, commercial buildings, and utility feeder systems. The pad-mounted, ground-level design allows installation on concrete foundations, making it suitable for urban distribution networks, industrial parks, and infrastructure projects with limited installation space.

With an oil-immersed design and natural cooling, the transformer offers reliable thermal performance under continuous operation. It is manufactured in accordance with ANSI / IEEE standards and is widely applied in North American–style distribution systems where standardized pad-mounted equipment is preferred.

What Are the Key Engineering Considerations for Upgrading Distribution Transformers?

Upgrading your transformers seems simple, but a wrong move can cause costly downtime and inefficiencies. This guide prevents that. Key engineering considerations for a transformer upgrade include precise load analysis, lifecycle cost assessment, selecting the right type (oil vs. dry), ensuring installation compatibility, and planning for future maintenance. A holistic approach ensures reliability and cost-effectiveness […]

When Should Distribution Transformers Be Replaced Instead of Reinforced?

If your distribution transformer is aging, the risk is not just failure. It is unplanned outages, safety exposure, missed capacity growth, and long procurement lead times that turn a small problem into a multi-year headache. Replace (not reinforce) when the unit shows irreversible insulation aging, repeat internal fault behavior, lost thermal margin, or when the […]
