Profile: Atl Transformers Ltd designs and manufactures transformers, inductors & wound components. Our low voltage high power modular systems are manufactured and engineered to specific customer specifications. They are suitable for individual switching of multiple thyristor stacks on large OEM machinery. Our heat treatment transformers are designed for duty cycle and are manufactured with vertical cooling ducts within the coil windings. Chimney ventilation within the transformer clamps and other design features prevents any localized heating reducing the overall temperature rise of our transformers. Multiple primary and secondary voltages are available and all come complete with tap changing facility.
