Cable strength member

A nonmetallic, nonconductive strength member for use in a cable or as a component of a strength reinforcement system of a cable is provided. The strength member is constructed of low cost materials and includes multiple glass fibers coated with a coating composition. The strength member provides flexibility and high tensile strength. The strength member exhibits low smoke generation and low flammability properties. The coating composition includes at least a lubricant that imparts a substantially smooth surface and a low coefficient of friction to the glass fibers to help facilitate processing of the strength member(s) during cabling and stranding procedures. The coating composition also includes at least an adhesive component that helps to substantially adhere the glass fibers together and helps to form the glass fibers into the strength member. The strength member can be configured as a yarn or as a strand for incorporation within a cable and/or for arrangement with one or more cable components.
