An electrical transmission line for conveying and limiting current by using a plurality of tubular portions made from a superconductive material. The tubular portions have a high critical temperature and are connected end-to-end by flexible, electrically conductive metal or alloy joints. A cryogenic fluid flows inside a first tube within the tubular portions. A vacuum is maintained inside a second tube around the tubular portions.

Superconductive electrical transmission line

A method of verifying that a given insulative element conforms with a reference insulative element, comprising the steps of: emitting a primary beam of electrons impinging on the given insulative element, receiving a secondary beam of electrons returned by the given insulative element in response to emission of the primary beam of electrons, and comparing a curve as a function of time of the electrical current of the secondary beam received with a curve as a function of time of a reference electrical current to establish whether or not the given insulative element conforms to a reference insulative element.

The present invention concerns a joint for electrical cables comprising at least a first layer constituted by a mixture of a polymeric matrix and a filler which is constituted by polymer comprising functions in its monomer units which homogeneously distribute the electrical filed, surrounded externally and coaxially by a second layer constituted by an elastomer. The layers are intimately associated with each other with an adherence greater than or equal to 5 N.cm.sup.-1.
