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.

A technique facilitates splicing of a power cable including splicing of a protective lead barrier. According to the technique, the power cable comprises conductors which form individual phases of a multi-phase conductor assembly. The conductors may be individually spliced for each phase of the multi-phase conductor assembly. Subsequently, splicing of the protective lead barrier may be performed by utilizing a lead based tape which is wrapped, e.g. helically wrapped, around the conductors. The wrapping technique provides a gas seal with respect to each individual insulated conductor within the multi-phase conductor assembly. Depending on the specifics of a given application and environment, additional layers may be added to ensure formation of a desirable splice.
