10374401 · 2019-08-06 ·

The device and process disclosed relates to hot sticks suitable for working on high voltage conductors in high temperatures. The enhanced hot sticks include a thermal insulating piece between the pole and the end tool. The disclosed hot stick retains electrical and mechanical properties at least as good as those of regular hot sticks and can be used on high temperature lines in the same way as regular hot sticks are presently used to perform live work on normal lines.

STRUT INSULATORS

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.

CABLE STAPLE ASSEMBLY AND SYSTEM

Frangible connectors can extend between and can alone couple adjacent insulator bodies together. The insulator bodies can also include counteracting frangible connectors that can be spaced from and coupled solely to a single one of the plurality of insulator bodies. The counteracting frangible connectors provide a counteracting shearing operation, which can help counteract the counterclockwise rotational movement that the frangible connectors tend to impart as they are sheared. The insulator bodies can be mounted on staples. The insulator bodies can have an upper bridge profile and the staples can have a lower crown profile opposing the upper bridge profile. The lower crown profile and the upper bridge profile can have opposite end portions that engage each other and can have central portions that are simultaneously spaced from each other to provide a central space between corresponding central portions of the insulator bridge and the staple crown.
