ABSTRACT:
An apparatus is provided for removing a protective armor wrapping, known as a preform, from a live electric power conductor. The apparatus mounts on an insulative rod, or hot stick, so that it can be remotely operated. The conductor is seated in a generally U-shaped, longitudinal channel member of the apparatus and then enclosed in the channel by a cover portion to form an elongated sleeve. After the conductor is in place within the sleeve formed between the cover and the channel member, the sleeve is moved along the conductor until a leading edge on the apparatus engages the preform. The preform is then stripped and unwound by rotating the apparatus.
