A bundle lifter for lifting a sub-conductor bundle having a plurality of spaced-apart sub-conductors, includes a base platform adapted for rotational mounting onto a single point conductor lifter, four sub-conductor wire cages mounted on the platform to support a sub-conductor thereon, each wire cage adapted to releasably hold a single sub-conductor and to swivel relative to the platform, wherein when the wire cages are positioned under the sub-conductor bundle, the wire cages are swivelled to align their corresponding rollers with a corresponding sub-conductor for rolling support of the sub-conductor on the roller as the bundle lifter is elevated on the support upwards from under the sub-conductor bundle to simultaneously pick each sub-conductor in the bundle into its wire cage for translation of the bundle from an original position to a new position spaced apart from the original position.

An implosion shield of ballistic fabric adapted to mount so as to surround an implosion sleeve or dead-end on a power line. The implosion shield may be wrapped or formed as an envelope or tent including one piece and folded around the implosion sleeve or dead-end and secured with fasteners. A method of installing the implosion cover may include installing an implosion sleeve or dead-end on a power line, and then installing the implosion shield around the implosion sleeve or dead-end, by wrapping the implosion shield around the implosion sleeve or dead-end, or by securing an envelope implosion shield over the implosion sleeve or dead-end, or by draping the shield over the implosion sleeve or dead-end, or by mounting the shield on a frame over the implosion sleeve or dead-end, then detonating the implosion sleeve or dead-end. The implosion shield attenuates shock, pressure and sound waves from the detonation.

Implosion shield apparatus and method

A method and apparatus for calculating line sag in a span of a conductor is provided. The method includes using a portable smart device having one or more accelerometers and running a line sag application on the processing device. The line sag application enables acceleration data of return waves generated on the conductor to be collected using the smart device and to be plotted as a function of time for display on the smart device. The method further includes placement of time markers on the plotted data displayed on the smart device to determine elapsed time and calculating line sag using the elapsed time.
