ABSTRACT:
A section insulator for insulating adjacent sections of contact wire of overhead power supply systems for electrified railway lines and the like is disclosed. The section insulator is interposed between separated ends of adjacent sections of contact wire. Strain plates are secured to the opposed ends of the sections and a strain insulator is secured to the strain plates above the level of the contact wires to maintain the tension in the contact wires. Spaced runners supported by the strain insulator extend between the contact wires, there being air gaps between the ends of the contact wires and the runners. A pair of diverging glider arms is secured to each contact wire section adjacent its end. The glider arms extend toward each other beyond the ends of the contact wire sections and overlap the ends of the runners, there being transverse air gaps between the diverging glider arms and the runners. The system thus provides a smooth under run from one section of contact wire along the diverging glider arms to the runners, then to the other pair of diverging glider arms and to the other section of contact wire. The insulator is supported by members extending vertically from the strain plates to a messenger wire, bridle, or other appropriate support. The section insulators can be adapted to use in ordinary catenary systems, compound catenary systems, ordinary direct suspension trolley systems, and as phase breaks for alternating current systems.
