A clamp device includes an end cap having a sidewall enclosing a hollow interior for receiving an operative end of a hot stick. A first jaw is fixedly mounted to the end cap. A second jaw movably engages the first jaw to grip an object. A support structure is provided to which the second jaw is fixedly mounted. The support structure passes through an opening in the end cap and is movably connected to either the end cap or first jaw such that the second jaw engages the first jaw upon displacement of the support structure. A connector of the support structure connects to a movable connector of the hot stick such that the support structure is displaced upon displacement of the movable connector, thereby engaging the second jaw with the first jaw to grip the object, wherein a reverse displacement of the movable connector releases the object.

A disconnect switch including a main disconnect switch integrated with a bypass switch. The purpose of he bypass switch is to provide a parallel path for temporarily closing the disconnect switch so that the main disconnect switch can be tested (i.e., opened and closed) without interrupting the power flow through disconnect switch. The bypass switch is integrated with the main disconnect switch and supported by the same insulator structure, which avoids duplication of parts and provided for a compact unit suitable for deployment on a pole or other mounting structure outside a substation. The bypass switch also includes a frame-mounted linkage at ground voltage operated by an actuator at ground voltage, which avoids the use of “hot sticks” to operate the bypass stitch.

A telescopic hot stick or pole for manipulating a tool from a position a selected distance away from a workpiece wherein the hot stick includes a tubular first section having a female end and a predetermined non-circular cross-sectional shape. A second section has a male end slidably engaged within the first tubular section and a predetermined non-circular cross-sectional shape conforming in a close-fit relation to the shape of the first section to prevent significant relative rotation of the second section therein. A locking assembly maintains the second section in an extended position where locking is accomplished in response to a sliding of the second section to the extended position and may be disengaged to permit ready removal of the second section from the first section.
