REPAIRING METHOD OF WIRE ANCHORING PART IN OVERHEAD TRANSMISSION LINE AND COMPRESSION-TYPE ANCHOR CLAMP USED IN THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a repairing method of a wire anchoring part, which enables the improvement of the electrically and mechanically deteriorated part of an already installed compression-type anchor clamp and achieves a permanent counter measure. ;SOLUTION: Figures show a status before the repair (a) and a status after the repair (b). An overhead transmission line 6, which is anchored to a tower by a compression-type anchor clamp 3, is cut off at the end position P of the already installed compression-type anchor clamp 3 (cut length of the wire 6=F) and, further, the compression-type anchor clamp 3 is removed from the tower side. Thne, as shown in figure (b), the overhead transmission line 6 which is cut to be shorter by a length F is anchored to the tower by a compression-type anchor clamp 3A, whose length is longer than that of the clamp 3 by the cut length F. The overhead transmission line 6 can be anchored by the new compression-type anchor clamp 3A, in the same way as the anchorage by the already installed compression-type anchor clamp 3.;COPYRIGHT: (C)1998,JPO
