Qinhuangdao OPGW national standard optical cable manufacturer complies with the price of State Grid OPGW-24B1-70 optical cable

Description :

　　How much does OPGW fiber optic cable with 48 cores cost? Shandong 12 core fiber optic cable communication cable factory

　　OPGW optical cable, also known as fiber optic composite overhead ground wire, places optical fibers in the ground wire of overhead high-voltage transmission lines to form a fiber optic communication network on the transmission lines. This structural form combines the dual functions of ground wire and communication. OPGW optical cable is more reliable, stable, and firm due to the wrapping of metal wires. As the overhead ground wire and optical cable are combined into one, it not only shortens the construction period but also saves construction costs compared to using other types of optical cables.

　　[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.
