Now that only the windings are immersed in oil, for cooling and dielectric purposes, the oil volume can be reduced by up to 70 percent when compared to a classic transformer. The new approach also brings a reduction of up to 20 percent in weight. The weight saving can then be reinvested in heavier windings using thicker copper wiring that improve the energy efficiency of the transformer by 50 percent, cutting electrical losses in half ➔ 3. A place for everything . . . For high-power transformers, the amount of oil is not as significant as the amount of copper or steel used, which means there are high-power cases where Effilight does not provide a significant weight reduction advantage. The full benefit of Effilight is achieved in the lower power ratings. The reason for this is the filling factor (the ratio between the weight of copper and steel versus the total transformer weight) tends to decrease when power decreases ➔ 4– 5. . . . and everything in its place The prototype has been built and tested for roof-mounting, however the Effilight traction transformer has been designed to be modular. This means that the “active part” windings and the enclosure require no redesign to adapt them for different mounting positions, be that roof mounted, underframe or in a machine room ➔ 6 – 7. Naturally this brings economies of scale and repetition advantages for train manufacturers and easier maintenance for operators. It means that a variety of different equipment can be fitted with the same transformer, resulting in reduced training costs by using the same transformer across their fleet. Maintenance and protection functions are the same for Efflilight and classic transformers, which means an existing transformer can be replaced by an Effilight without affecting existing maintenance and protection systems or processes. An existing transformer can be replaced by an Effilight without affecting existing maintenance and protection systems or processes. Future on track Today, more than half the world’s trains are powered by ABB traction transformers, and most of the world’s train manufacturers and rail operators rely on them.

6 Effilight is suitable for all the different assembly positions Machine Room Roof mounted Underframe 7 Efficient traction transformers – comparing technology and application Parameters Classic Effilight ® Lightweight variant ✓ 25 kV option ✓ ✓ Wind speed cooling possible ✓ Roof mounted ✓ ✓ Machine room mounted ✓ ✓ Underfloor mounted ✓ ✓ Lifetime 40 years 40 years includes oil insulation, continues the guarantee expected from an ABB transformer of a 40 year lifetime. Achieving substantial weight reduction through the Effilight technology allows ABB to deliver to its customers a new degree of freedom which was not previously existing: a choice of weight reduction and energy efficiency increases. It is possible to tailor the solution to specific needs for specific train platforms, allowing for instance the weight to be reduced by 10 percent while still increasing the efficiency by 20 to 30 percent. Effilight may currently be a young upstart, but its future looks sparkling. Light it may be, but in terms of lifetime, efficiency and delivery, a lightweight performer it is not.
