The invention relates to a long-distance line (1) for high voltage, having an outer jacket pipe (2) extending in a longitudinal direction (5), having an inner conductor (3) led in the interior of the jacket pipe (2) in parallel to the longitudinal direction (5), and having a number of mounting insulators (10), by means of which the inner conductor (3) is held on the jacket pipe (2) at a distance therefrom transverse to the longitudinal direction (5), and a correspondingly embodied mounting insulator (10). The mounting insulators (10) serve for adjusting the distance between the inner conductor (3) and the jacket pipe (2). The long-distance transmission line (1) is particularly air insulated in design. The mounting insulators (10) allow simple assembly and installation of the inner conductor (3).

摘要:
A superconducting cable includes a first conductor layer formed of superconducting wires, and an insulating layer formed at the outer periphery of the first conductor layer. The first conductor layer is an assembly of a plurality of superconducting wires obtained by forming an RE based superconductor layer on a metal substrate. The current is limited by an electrical resistance generated when the current of the first conductor layer exceeds the critical current, thereby preventing the superconducting cable from being damaged. A superconducting cable line is formed of a base and a current limiter, which is formed by using the above-described superconducting cable. Accordingly, when a current exceeding the rated current of the base flows, it can be damped.

In a thermally insulated double pipe, a structure is provided in which an inner pipe may be prevented from being appreciably offset relative to an outer pipe due to thermal contraction. The structure includes an inner pipe 101, within which a superconducting cable is mounted, an outer pipe 103 within which the inner pipe is housed, with the inner and outer pipes constituting a thermally insulated double pipe, and an inner pipe support member 104 supporting the inner pipe. The inner pipe support member 104 is secured to the inner and outer pipes.
