Introduction This introduction is not part of IEEE Std 1594-2008, IEEE Standard for Helically Applied Fiber Optic Cable Systems (Wrap Cable) for Use on Overhead Utilit
6、y Lines. This standard is the first standard focused on fiber optic cables that are wrapped around either an overhead conductor, the ground wire (sometimes called earth wire) or a messenger wire. This type of system is typically utilized where optical fiber is desired to be installed in the overhead
7、 transmission line right-of-way and where other fiber optic options either cannot be utilized or there is some constraint preventing their use.

44、 requirements 4.1 Support systems Support systems for the cable itself are not required. The ground wire, phase wire, or other messenger in overhead power facilities around which the cable is wrapped provides all the support for the composite system and eliminates the need for the cable to be self-s
45、upporting. 4.2 Fiber optic cable core The fiber optic cable core shall be made of coated glass optical fibers housed to protect them from mechanical, environmental, and electrical stresses. Materials used within the core shall be compatible with one another, shall not degrade under the electrical st
46、resses to which they may be exposed, and shall not evolve hydrogen sufficient to degrade optical performance of fibers within the cable. 4.2.1 Fiber strain allowance The fiber optic cable core shall be designed so that the fibers remain tensile stress-free under the maximum working elongation of the
47、 cable being wrapped on, and taking into consideration strains created during the installation. 4.2.2 Central structural element If a central structural element is necessary, it shall be of reinforced plastic, epoxiglass, or other dielectric material. If required, this element shall provide the nece
48、ssary tensile strength to limit axial strain on the fibers and minimize fiber buckling due to cable contraction at low temperatures. 4.2.3 Buffer tube filling compound Loose buffer tubes shall be filled with a suitable compound compatible with the tubing material, fiber coating, and coloring to prot
49、ect the optical fibers and prevent moisture ingress. 4.2.4 Cable core filling/flooding compound The design of the cable shall include a suitable filling/flooding compound or water-swellable material in the interstices to prohibit water migration along the fiber optic cable core. The filling/flooding compound or water-swellable compound shall be compatible with all components with which it may come in contact. 4.2.5 Binder/tape A binder yarn(s) and/or layer(s) of overlapping non-hydroscopic tape(s) may be used to hold the cable core elements in pla
