Aerial branching manner of distribution line and aerial branching structure null of

摘要

PROBLEM TO BE SOLVED: To improve reliability, and to reduce cost by branching a distribution line in constitution, in which the number of parts is decreased and workability is enhanced and which is lightweight and simple. ;SOLUTION: A messenger wire 25 in which one spacer 26 made of high molecules is interposed in the midway in the longitudinal direction is tensecd to a section lower than a main track 23, and branch lines 24 branched from the main track 23 are supported to ring members 33 mounted on the spacer 26 by clamps 36. Accordingly, even when a dead-end insulator, a pin porcelain insulator for peripheral edge or the like is used, the branch lines 24 can be supported easily to the messenger wire 25 in which the spacer 26 is interposed under an insulated state as they are.;COPYRIGHT: (C)2000,JPO
