COMPRESSED GAS INSULATED TRANSMISSION LINE

摘要

PROBLEM TO BE SOLVED: To provide a structure capable of smoothly leading stranded conductors in a conductor lead-in conduit and preventing the stranded conductors form being loosened, for a compresed gas insulated transmission line having a lead-in conductor system. SOLUTION: In this compressed gas insulated transmission line, an insulating gas is sealed in a sheath conduit, a conductor lead-in tube is provided in the insulating gas, and stranded conductors 4 are stored in the lead-in tube. A coating of a member having low friction coefficient is applied on the stranded conductors 4. Winding a stainless tape 5 and coating a fluororein are cited as examples of this coating. The stranded conductors are prevented from being loosened by smoothly leading in the stranded conductors by making frictional resistance of their surfaces small and bundling them by the coating.
