What is the life cycle of a traction transformer, and what factors affect it?

The life cycle of a traction transformer typically ranges from 25 to 40 years, depending on operating conditions and maintenance practices. Factors affecting its lifespan include thermal stress from load fluctuations, electrical stress from voltage spikes, mechanical stress from vibrations, and environmental conditions like temperature and humidity. Regular maintenance, such as oil analysis and component inspections, can extend the transformer’s life. Overloading, inadequate cooling, and poor maintenance can significantly reduce its operational lifespan.
