ACTOM Power Transformers manufactures transformers from 16kVA up to and including 315MVA with voltages up to 300kV. These transformers are supplied to electricity distribution utilities, the mining sector, industrial plants, public works authorities and turnkey contractors. The power transformers are mostly of the step-down type, equipped with on-load tap changers, either naturally cooled or, for larger units, incorporating forced oil and air-cooling.
The basic units are of three-phase, three-limb construction, comprising fully mitred low-loss cores of the boltless type with disc HV and helical or disc LV and tapping windings.
