Cryogenics and Aluminum in Electrical Manufacturing

  • P. Burnier
Part of the Advances in Cryogenic Engineering book series (ACRE, volume 11)


The rating of electrical generators and transformers has risen from 50 MVA to more than 600 MVA during the last twenty years. This has been possible through higher stresses on conductors, insulators, and magnetic materials. The progress made simultaneously on dielectric and magnetic materials has kept the corresponding losses at a relatively low level; however, the losses in the windings become substantial for the larger units, since the resistivity of copper has not changed. Cryogenics offers a new means in overcoming this difficulty by using either superconductivity or the normal conductivity of high-purity metals at low temperatures.
