Embodiment Construction

[0094] figure 1 Aspects of an embodiment of a high voltage power line 106 according to the invention are schematically shown. figure 1 In , which is a partial cross-sectional view for illustrative purposes, the high voltage power line is assembled and is thus in an assembled state. The high voltage power line includes a plurality of elongate electrical conductor segments 102 arranged side by side and in electrical contact with each other to form an inner electrical conductor 104 of the high voltage power line 106 . By its tubular overall shape, the high voltage power line 106 defines a longitudinal axis 113 . The high voltage transmission line 106 may be a high voltage direct current (HVDC) transmission line or a high voltage alternating current (HAVC) transmission line. The high voltage power transmission line comprises an elongated tubular electrical insulation device 108 arranged to receive and surround an inner electrical conductor 104 formed by electrical conductor segm...

Abstract

A HV power transmission line (106) with at least two tubular electrical insulation devices (108), at least one electrically uninsulated nominal conductor segment (102) and a joint (1 17) for jointing the ends of the insulation devices plus at least one power termination (109) for connecting the transmission line. The insulation device (108) is flexible, has an inner electrically conductive layer (1 10) at its inner wall surface, and is of such insulation quality that it can electrically insulate the conductor segment (102) from the exterior of the insulation device once inserted into the tubular insulation device. Once inserted the uninsulated conductor segment touches the inner electrically conductive layer (1 10) at an inner wall surface of the tubular electrical insulation device such that the inner electrically conductive layer (1 10) is on the same electric potential as the conductor segment in an operating state of the HV power transmission line each.

Description

technical field [0001] The present invention relates to a high voltage transmission line for continuous transmission of electricity comprising a plurality of elongated conductor segments placed side by side to form an inner electrical conductor of the high voltage power transmission line and an elongated tubular conductor arranged to receive and surround the inner electrical nominal conductor segment Insulation device. [0002] A conductor segment is to be understood as a nominal conductor segment which is electrically connectable to an adjacent conductor segment in the direction of the longitudinal axis defined by the tubular overall shape of the high voltage power line and which forms a conductor together with other side-by-side extending conductor segments. The term conductor segment and the term power line segment are to be understood as the longitudinal section of the overall nominal conductor and the overall power line, respectively. Background technique [0003] The ...
