Abstract: An apparatus providing a permanent pole step and/or attachment mount for removable steps, accessories or equipment for hollow poles that is practical and economical to use, and that provides a substantially horizontal step or mounting surface that does not rotate and that extends only a limited distance from the hollow pole. A pole step having a support member and a mating plate, where a portion of the support member is inserted into a mounting hole of the pole and the remaining portion of the support member protrudes out of the hole to create a stepping surface. The plate has a tongue which mates with the support member in the mounting hole to secure the support member. An attachment mount for attaching temporary steps, equipment or accessories to a hollow pole, having a support member, a mating plate and a guide washer. The plate receives the support member, and the tongue which mates with the support member in the mounting hole to secure it in place.

Abstract: An integrated electrical system includes a first conductor for receiving current from power lines or other equipment. The conductor is coupled to a conventional vacuum switch for controlling flow of current through the system. A current collector coupled to the vacuum switch collects current from the vacuum switch. A second conductor coupled to the current collector delivers current to equipment or lines externally of the device. The components of the system are housed within an inner epoxy encapsulated within Polysil. The epoxy preferably has temperature characteristics which are similar to that of Polysil to prevent cracking due to temperature stress. At least one sensor may also be provided integrally with the components for detecting faults or for sensing general power line conditions. A preferred voltage sensor has resistive shielding for accurate sensing in adverse environments.
