A support body comprising several support elements lined up one behind the other is disclosed. More particularly, each support element includes a structure which is formed by support rings connected together by bridge members and which is provided at one end with extensions which can engage or be pushed into the end or last support ring of a preceding support element. Moreover, each support element is provided with additional means for limiting the degree of sliding-apart of the element from the element to which it is connected. The present support body has the advantage that its support elements as well as the connections between such elements are sufficiently mechanically stable so that no special guides for the support elements are necessary when the former are being wrapped.

Support body for the conductors of a low-temperature cable

In apparatus for supplying power to electrical devices having conductors cooled to a low temperature and in which the apparatus establishes connections between normal conductors at room temperature and the cooled conductors, with the end of the cooled conductors which are connected to the normal conductors located in the gas flow of an evaporated coolant, means are provided to supply an additional cold gas into the gas flow of the evaporated coolant at a temperature level which is above the evaporation temperature of the coolant thereby permitting the conducting cross-sectional areas of the normal conductors in the apparatus to be designed only for an average operating current and to thereby reduce coolant losses.

Apparatus for supplying power to electrical devices having conductors

A multi-layer insulation for deep-cooled cables utilizing insulating foils having a dielectric loss factor less than 5.times.10.sup..sup.-5 in which a layer of a spun bonded paper of high density polyethylene fibers is placed between each two layers of insulating foil thereby providing sufficient elasticity even when the cable is cooled to a very low temperature to equalize expansion differences occurring in the cable.
