Toroidal Transformers
Swift Heat is the sole manufacturer of Toroidal Transformers in South Africa
The main advantage in using toroidals is achieved through the construction of the core which is wound in a tight round shape from a continuous strip of grade M4 grain-orientated silicon steel. This allows for a higher flux density with much lower eddy current and hysteresis losses resulting in extremely high electrical efficiencies (>90%) compared to the standard types.
