Transmission Line Repair (Bare Hand) - Instant Video
This 54-minute video explains the theory and practice involved in using the bare-hand method to perform live transmission line repair. Covers what bare-hand repair work is, why it works, and how it is done. The basic theory of bare-hand work is presented, as well as the equipment used to perform this work. Installation of a repair sleeve is used as an example, to illustrate how the principles of bare-hand work are applied. Safety is emphasized throughout the unit.
