Abstract: A hybrid rope constructed of a plurality of strands, wherein each strand is constructed of a fiber center, a jacket surrounding the fiber center, and a plurality of wires surrounding the jacket. The fiber center can be constructed of one or more high-strength synthetic fibers or yarns. The jacket can be constructed of polypropylene, thermoplastic polyurethane, high-density polyethylene, linear low-density polyethylene, nylon or other similar materials. The jacket can have a braided or woven design and adds a protective layer between the fiber center and the wires. The wires can be constructed of high-strength steel wires, galvanized steel or stainless steel. The fibers or yarns that make of the fiber center are twisted to lay right and then covered with the jacket. The wires then surround the jacket and are twisted to lay to the left. This creates a torque-balanced condition of the hybrid rope.
