<p><P>PROBLEM TO BE SOLVED: To provide a stringing structure of a transmission line in which differences in the degree of slacking will not appear between horizontal element conductors of a multiple conductor transmission line, twisting is less likely to occur, excessive snow accumulation will not be reached, and galloping is suppressed effectively. <P>SOLUTION: In a twisting resistant low centroid multiple conductor transmission line, where three or more element conductors are arranged into a right-left symmetry and into a regular polygon, the stringing structure comprises a spacer obtained by fixing a fixed grip and/or a loose grip movably to a spacing body, the grip of the spacer, having a larger mass, is located below in the line direction and fixed to grip the element conductor. Fixing interval of the spacer is made dense at the support point side within the span and rough in the vicinity of the center within the span. The spacers are fixed uniformly, such that the large mass grip side is located below, thus preventing galloping. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
