  • Method for manufacturing a superconducting magnet
    Patent number: 5084955
    Abstract: A method for manufacturing a superconducting magnet comprising the steps of applying a bonding agent on a length of a superconductor by passing the superconductor through a bath of the bonding agent to thereby coat the superconductor with the bonding agent. The superconductor coated with the bonding agent is simultaneously wound to form a winding which is then hardened by heating for example to form a rigid winding without voids.
    Type: Grant

  • Insulating oil and electrical apparatus filled with the same
    Patent number: 4770816
    Abstract: An insulating oil containing N,N-bis(2-hydroxyethyl)-N-cyclohexylamine at 0.5 mg/l or more. An electrical apparatus is filled with the insulating oil in which a copper component is immersed. During operation of the apparatus for a long period of time, the tan .delta. of the insulating oil does not increase so that deterioration of the insulating oil is deferred, thereby substantially extending the life of the insulating oil.

  • Transformer having forced oil cooling system
    Patent number: 4095204
    Abstract: A transformer having a forced air cooling system is disclosed. The transformer includes an insulating oil which is forcibly moved in the transformer and an insulating sheet which is partially covered with particles, fibers or other forms of an inorganic material for producing a static charge of opposite polarity to the charge produced by the base material of the insulating sheet caused by relative motion due to forced flow of the insulating oil.
