Abstract: A strut insulator for an overhead rail contact system includes a first end fitting, the first end fitting defining an inner side pocket, and a second end fitting spaced from the first end fitting, the second end fitting defining an inner side pocket. The strut insulator further includes a rod extending between the first end fitting and the second end fitting and extending into the inner side pockets of the first and second end fittings, the rod defining a length. The strut insulator further includes a shell surrounding a portion of rod, the shell extending along a portion of the length of the rod, the shell formed from a fluoropolymer.

Abstract: The rigid T-rail conductor system is configured to support a contact wire in an overhead railway electrification system. The rigid T-rail includes a first rail configured to be disposed in an overhead position of the railway electrification system. The rigid rail includes a keeper disposed on a side of the first rail, the keeper configured to be movable. When the keeper is in the first position, the keeper holds and affixes the wire on the first rail. When the keeper is in the second position, the keeper allows the wire to be installed or to be removed from the rail.

Abstract: A dead-end termination clamp including a cast body, a clamping end, and a connection end. The dead-end clamp may be scaled to support various size wires or cables. The dead-end clamp may be able to provide a support strength less than, equal to, or exceeding the breaking strength of a supported cable. A collet with a length, two ends, a central cavity and at least one helical slot running along the length of the collet. The at least one helical slot may have a varying width or pitch along the length. The at least one helical slot may terminate before reaching one or both ends. The collet may have one helical slots which runs the entire length of the collet. The collet may be substantially cylindrical or another shape. The center cavity may be substantially cylindrical or another shape.

Abstract: A modular crossing assembly structure in an overhead contact system. The modular crossing assembly structure includes a plurality of rail underrunning contact segments and a body to which the plurality of these rail segments are attached, where the plurality of rail segments are connectable to an overhead conductor rail and/or overhead contact system. The plurality rail segments are securely affixed to the body by one or more connectors.

Abstract: Methods for manufacturing strain insulators are disclosed. The methods may include swaging and/or crimping, by a die-set, a sleeve of an end fitting on a portion of a core strength rod, the portion being disposed inside the sleeve of the end fitting. The swaging may be performed by an upper block and a lower block of the die-set. At least one of the upper and lower blocks may be movable such as to allow for compressing the sleeve of the end fitting on the rod disposed between the blocks. The upper block may include a plurality of protrusions extending lengthwise on the upper block and the lower block may include a plurality of protrusions extended lengthwise on the lower block.
