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.
