OPGW optical fiber composite overhead ground wire，also known as optical fiber composite overhead ground wire in Chinese. Placing optical fibers in the ground wire of overhead high-voltage transmission lines is used to form the optical fiber communication network on the transmission line. This structural form combines the dual functions of ground wire and communication，and is generally referred to as OPGW optical cable.
1、The design adopts a stainless steel tube fiber optic unit and other metal wires twisted simultaneously；
2、Placing the optical fiber inside a stainless steel tube can achieve better excess length；
3、Accurately designed fiber optic cable cross-section ensures the electrical performance，mechanical and physical properties，and thermal stability of the cable；
Applications：Various new power lines and reconstruction of existing power lines
Laying method：Overhead
Working temperature：-40℃~+70℃
Bend radius：Static 15 times the cable diameter；Dynamic 25 times optical cable diameter
1、According to the technical conditions of the line，products that meet the technical requirements of the line can be obtained by combining the proportion of aluminum steel cross-section without changing the structure of the optical cable；
2、The thin-walled stainless steel tube OPGW optical cable structure has higher resistance to lateral pressure and impact compared to the aluminum tube structure；And stainless steel has low conductivity，high strength，excellent corrosion resistance，and well protected optical fibers；
3、Stainless steel pipes filled with ointment can prevent moisture or moisture from penetrating；Adjusting the excess length of the optical fiber can make the cable have good temperature characteristics；
4、Aluminum clad steel wire with high strength and low conductivity bears the self weight and external load of OPGW；By utilizing the principle of charge skin effect，overload or fault short circuit currents are guided through outer good conductors，which is beneficial for protecting optical fibers；
5、Optical cables have similar mechanical and electrical characteristics to conventional overhead ground wires，facilitating the replacement of old ground wires and the design and installation of new ground wires. They also have the dual functions of ground wire and communication.
6、The excess length of the optical fiber can be precisely controlled to ensure the ability of the optical cable to withstand high loads and large spans；
