Hybrid electric optical cable for overhead construction

摘要

(57) Abstract It has three insulated phase conductors which around the holding rope are wound in spiral condition, it is the hybrid electric optical cable where electrical distribution and the one for telecommunications are overhead constructed. One which is installed in tubular structural internal it resists to the compression to cross direction optical fiber element exists at least inside the holding rope, the support structure which has resistance vis-a-vis longitudinal direction tension exists around the above-mentioned tubular structure.
