ABSTRACT:
A compressed gas-insulated transmission line (CGIT) system, apparatus and techniques are disclosed in which extruded grooves along the inner surface of an encasing sheath are provided for simplified alignment and mounting of insulative spacers. The spacers, mounted to the alignment grooves, support current-carrying conductors within the sheath assembly in either a sliding or fixed relationship to the groove. Spacers in a sliding configuration may be provided with bearings to further simplify alignment. The spacers can be aligned longitudinally to permit the optimization of the mechanical and electrical characteristics of the system. Traps for unwanted particulate matter at large within the system may be provided by arcuately mounted perforate plates across the grooves, by radially mounted perforate fixtures, or by lips at the junction of the arcuate segments comprising the encasing sheath. Spacer and trap configurations can be combined in a single assembly.
