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

A long-distance transmission line for high voltage having an outer casing tube which extends in a longitudinal direction, having an inner conductor which is routed parallel to the longitudinal direction in an interior of the outer casing tube and having a number of holding insulators, via which the inner conductor is held transversely with respect to the longitudinal direction on the outer casing tube and at a distance from the outer casing tube, wherein:
- the holding insulators are designed for adjustment of the distance between the inner conductor and the outer casing tube;
- the outer casing tube has a number of holding sockets which face outward, each of which holds an external threaded connection of a holding insulator;
- and
- the inner conductor has a number of holding sockets which face inward and each holds an internal threaded connection of a holding insulator.
A holding insulator for separated attachment of an inner conductor in an interior of a casing tube, wherein:
- the holding insulator is designed for adjustment of a distance between the inner conductor and the casing tube;
- the holding insulator comprising an insulating body which is essentially in the form of a rod and has a thread at each of its two ends;
- a metal fitting having a thread is provided for screw connection at each of the two ends of the rod;
- a polygon for rotation of the respective holding insulator is formed on at least one metal fitting;
- and
- the polygon attaches the metal fitting to a stalk with the polygon being pushed at least partially over the stalk end and being at least one of pressed and adhesively bonded onto the stalk end.
