Abstract: According to one embodiment of the invention, a ground wire insulation system for a utility pole includes a utility pole having at least one power line and a neutral line associated therewith, an elongated conduit formed from an insulative material coupled to the utility pole, and a ground wire disposed within the elongated conduit and coupled at an upper end to the neutral line and at a lower end to ground.

Abstract: An insulating cap and connector for attaching an electric utility cross arm assembly to a supporting metal utility pole having an open top. A cylindrical tube of insulated composition has an end cap closed at the top and has a reduced diameter nipple extending downwardly. The reduced diameter nipple is insertable within the open top end of the supporting utility pole when the tube is slid over the top of the utility pole. Fasteners attach the cross arm to the tube and the supporting utility pole. There is no conductive contact between the metal support pole and the cross arm when insulated fasteners are used.

Abstract: A cross-arm for supporting electric utility wires. The cross-arm is made of insulative material, the inner structure formed of alternate layers of polyester resins and synthetic fabric. An inner core is composed of polyester resin and particulate matter, or polyurethane foam with a central metal reinforcing bar. The cross-arm is modular in nature, and support members are integral with the unit, facilitating installation.
