OPGW optical cable is a kind of special optical cable commonly used in power system. It has high mechanical strength and reliability, but it is expensive. It is only suitable for new or planned transformation lines, and its application is limited.


Aerial ground bundled cable (ADSS cable) - this cable is very thin. Adopt stainless steel wire or special tape special machine to connect with ground wire, with good reliability. The metal free self-supporting optical cable is widely welcomed by the domestic power sector because of its special material and manufacturing process, high strength and corrosion resistance. Generally, ADSS optical cable fittings are installed below the phase line of the power line, so no power cut is required during construction and maintenance. The cost of the optical cable is between OPGW and ADSS. The length distribution principle of the optical fiber system. According to the route table provided, in order to facilitate transportation and construction, combined with the production process of the optical cable, generally, the length of the cable reel should be selected as the appropriate connection point. In principle, the natural slope, joint reservation, equipment reservation, traction head and sag should be considered on the tension tower convenient for transportation Degree, sampling length and other factors. In general, after reading the length of each optical cable according to the line span, the reserved coefficient and joint length shall be increased, and 30 m in front of the optical cable
