Fiber-optical cable with two-layer armor relates to area of optical communication. Cable that consists of core that includes central power element, optical modules with optical fiber made of polymer film, iyter coating, has laid over core two-layer wire armor and shall made of polyethylene with increased strength. Two-layer armor consists of round galvanized steel wires winded in spiral round core, at that repetition factor of twist pitch is within 12///14, and the shell is made of bi-modal polyethylene. Such cable provides stability of cable to stretching and bend and is optimal for conditions of laying in bulk and creeping earths. |
