　　 Advantages and usage introduction of OPGW optical cable

　　Fiber optic composite overhead ground wire (OPGW) is a ground wire that integrates communication optical cables and overhead transmission line lightning protection wires. It not only meets the technical requirements of fiber optic communication, but also meets the necessary characteristic requirements as a ground wire, including mechanical strength and electrical performance. Due to the fact that this type of ground wire embeds optical fibers in twisted wires and is installed on the top frame of high-voltage overhead transmission lines, it has the advantages of safety, reliability, no electromagnetic induction, and maintenance free. Therefore, it has been gradually applied in overhead transmission lines abroad since the late 1970s, and its usage has been increasing. According to incomplete statistics, OPGW optical cables have been laid for tens of thousands of kilometers worldwide so far. Since the 1990s, the use of OPGW optical cables in China has been increasing, with over 10000 kilometers of lines currently in operation.

　　According to the structural characteristics of OPGW, specialized fittings and accessories such as tension clamps, suspension clamps, vibration dampers, connecting plates, fastening clamps, down conductors, sag adjustment plates, jumper clamps, U-shaped hooks, and junction boxes should be used during line installation.

　　When replacing the old line ground wire with OPGW optical cable, it is necessary to choose an OPGW that is equivalent to the mechanical and electrical characteristics of the original overhead ground wire. That is, the outer diameter, unit length weight, ultimate tension, elastic modulus, coefficient of linear expansion, short-circuit current and other parameters of the OPGW should be close to the existing ground wire parameters. This can not only avoid changing the existing tower head and reduce the amount of renovation work, but also ensure the safe distance between the OPGW and the existing phase conductor, ensuring the safe operation of the power system. To meet these conditions, the cost of purchasing and installing optical cables will increase exponentially.

　　Product application: Power communication

　　Characteristics of OPGW optical cable products:

　　Combining the dual functions of ground wire and communication optical cable, it eliminates the huge cost of repeated installation and maintenance;

　　Installed on the top of the overhead power line tower, without considering factors such as hanging points and electrical corrosion;

　　During the renovation process of the old line, the outer diameter and tensile strength of the optical cable can be better matched than another ground wire;

　　Large transmission capacity, high communication quality, and good reliability;

　　Has superior mechanical and electrical performance;

　　Good safety performance, long service life, and less susceptible to destructive attacks
