Abstract: An apparatus and method for remotely blocking a cavity of a component of an energized electrical transmission system. A protector has a blocking part for blocking the cavity of the component. The protector has a hotstick connector. A dielectric hotstick has an engagement part such as a hook at a remote end of the dielectric hotstick. The hook may be removably connected to the external point of attachment for remote installation of the blocking part blocking the cavity within a component, such as a piece of equipment or support structure. The blocking part may be remotely installed blocking the cavity using a dielectric hotstick operated by a user who is in a position outside a safe Limit of Approach. The blocking part may comprise a compressible material such as rubber or memory foam.

Abstract: An applicator is disclosed for applying a tubular conductor cover to a cable, the conductor cover being split longitudinally to define a first longitudinal edge and a second longitudinal edge, the applicator comprising: a head having a separator shaped to contact, in operation of the applicator, an interior surface of the conductor cover to spread open the first longitudinal edge and the second longitudinal edge along a portion of the conductor cover to allow the portion of the conductor cover to be applied to a cable. A method is also disclosed of applying tubular conductor cover to a cable, the conductor cover being split longitudinally to define a first longitudinal edge and a second longitudinal edge, the method comprising: spreading open the first longitudinal edge and the second longitudinal edge of a portion of the conductor cover with a separator on a head, the separator contacting an interior surface of the conductor cover; and applying a length of conductor cover to the cable through the head.
