Abstract
An improved pole mount cable restraint insulator is described featuring a pin and bolt locking mechanism that may be used to secure a medium voltage 5 kV to 35 kV electrical cable to the insulator and riser pole. The cable restraint insulator includes a seat to secure the cable. A further improvement over existing cable restraints is the polymer insulating materials used in the construction. Such materials are lighter in weight, electrically track resistant, lower in cost and non-breakable. The cable restraint insulator may be constructed by injection molding and/or casting with variety of electrically insulating polymers.
