OPGW-48B1-90 OPGW-13-90-1 lightning protection wire optical fiber composite overhead ground wire optical fiber cable

Description :

　　[OPGW Optical Cable Characteristics]:

　　(1) Generally used for high voltage lines exceeding 110kV, with a large span (all above 250M);

　　(2) Easy to maintain, easy to solve line crossing problems, and its mechanical characteristics can meet the requirements for large line crossings;

　　(3) The outer layer of OPGW optical cable is made of aluminum clad steel structure, which has no effect on high-voltage corrosion and degradation;

　　(4) OPGW optical cables must be powered off during construction, resulting in significant losses. The OPGW optical cables used are generally used for new power lines;

　　(5) The higher the short-circuit current of OPGW optical cable, the more good conductors are needed for armor, which correspondingly reduces the tensile strength. However, in the case of a certain tensile strength, to increase the short-circuit current capacity, the only way is to increase the metal cross-sectional area, which leads to an increase in cable diameter and weight, and the strength of the transmission tower needs to be correspondingly increased.

　　[OPGW Fiber Optic Cable Supporting Hardware]:

　　Tension fittings: used for connecting with terminal towers, tension towers, towers with a turning angle greater than 25 °, and splice towers;

　　Suspension fittings: Pre twisted suspension clamps are connecting fittings used to suspend optical cables on transmission line towers;

　　Fasteners: realize the connection and installation of tension clamps and suspension clamps with towers;

　　Anti vibration hammer: an interference type anti vibration device that consumes the energy of cable vibration and suppresses cable vibration;

　　Junction box: It is the place where the end of OPGW optical cable is connected;

　　Surplus cable rack: used to place surplus optical cables during fiber optic cable splicing;

　　Pull down fixture: Tighten the OPGW optical cable from the tower to the tower to prevent shaking and avoid wear and tear of the cable.
