POWER TRANSMISSION LINE CONSTRUCTION METHOD AND POWER TRANSMISSION LINE FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a power transmission line construction method capable of appropriately preventing contact/short-circuiting between wires caused by a street jump phenomenon and a galloping phenomenon while taking an individual/specific installation situation into account, and a power transmission line facility.;SOLUTION: Wires 26-28 are anchored on two or more iron tower arms 16-18 that are arranged at different height positions of each iron tower 12, and the wires 26-28 are installed between the iron towers 12 that are installed continuously. Whether an additional construction is required is discriminated in accordance with horizontal offset amounts of the two iron tower arms 16 and 17 (17 and 18) and a combination of installation places of the iron towers 12. An insulation spacer 60 (62) is fitted between a pair of wires 30 (31) for which it is discriminated that the additional construction is required.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2017,JPO&INPIT
