CIRCUMFERENTIALLY CONTINUOUS, EXPANDABLE FIRE SUPPRESSING, DIELECTRIC SLEEVE

A coated textile sleeve has a textile wall having a circumferentially continuous outer surface extending along a longitudinal axis between opposite open ends, wherein the textile wall is formed at least in part by flame-resistant multifilament yarn. An adhesive layer is bonded to the circumferentially continuous outer surface, and an impervious coating is bonded to the adhesive layer. The coated textile sleeve is stretchable axially and radially, thereby allowing the coated textile sleeve to flex and be easily assembled into close conforming, wrinkle-free relation about the bus-bar regardless of the number of bends and shape of the outer contour of an outer surface of the bus-bar.
