The Truth About Cast-Resin Transformers
Debunking the myths surrounding aluminum usage
BY SCOTT MAY, VIJAI NARAYANAN, ANDREW LAWLESS, Siemens
Much has been written about the use of aluminum versus copper for transformer conductors within the electrical industry. Aluminum conductors have been used successfully in the electrical industry for more than 100 years; unfortunately, misconceptions about their applications still exist. In Europe, aluminum has been used as the standard material for cast-resin transformer windings for many decades.
However, following the...
