I. Project Background & Core Customer Pain Points

As Uganda continues to invest in the modernization of its power infrastructure, many existing substations are being upgraded to accommodate increasing electricity demand and improve grid reliability. This project required a high-capacity power transformer capable of supporting long-term stable operation while meeting local utility requirements.

The customer faced several key challenges during the project:

1. Large Capacity Requirement

The upgraded substation required a 63MVA transformer capable of handling increasing regional electricity demand while ensuring stable voltage regulation under varying load conditions.

2. High Reliability for Continuous Operation

As a key piece of equipment within the substation, the transformer must maintain stable operation under continuous heavy-load conditions, minimizing maintenance requirements and reducing unexpected outages.

3. Strict Project Schedule

The customer required technical confirmation, production, factory testing and shipment to be completed within only three months to avoid delaying the substation reconstruction schedule.

4. Long-term Operating Efficiency

To reduce lifecycle operating costs, the customer specified an all-copper winding design combined with a low-loss magnetic core, ensuring higher efficiency and longer service life.
