STRINGING REPLACEMENT WIRE NEAR ENERGIZED POWER LINES

摘要

A method of stringing replacement static lines on an energized overhead power line system, wherein both the old and new static wire is grounded at substantially each support structure within a pull zone during static wire maintenance and replacement operations, the method including at least the steps of (a) removing a length of an old static wire from the pull zone portion of the system; (b) stringing in a length of replacement static wire into the portion of the system; (c) maintaining an electrical connection between earth and the old static wire during step (a); and (d) maintaining an electrical connection between the earth and the replacement static wire during step (b), while at substantially all times maintaining a grounding connection from the old static wires and the new, replacement static wires to substantially each support structure, and therealong to ground, along the pull zone portion of the system.
