Abstract
Abstract A cantilever standoff for supporting a conductor in laterally spaced relationship to a line pole. A base member is attached to the pole and a standoff arm extends outwardly therefrom, its outboard end being provided with a suitable conductor support. The arm has a tapered, insulating body of synthetic resin material of progressively greater cross-sectional area toward the base member, and one or more longitudinally extending, loadbearing rods of uniform individual cross section are disposed within the body to increase its tensile strength and, in some forms of the construction, its compressive strength as well. The rods are composed of a synthetic resin that is longitudinally reinforced by glass fibers, the ends of the rods being rigidly anchored in the base member and the outboard conductor support. The body is provided with a series of integral skirts over its length to increase resistance to flashover. The base member may be specially configured to transmit shear stresses thereto.
