　　[OPGW Optical Cable]: The full Chinese name is Fiber Optic Composite Overhead Ground Wire. Placing optical fibers in the ground wire of overhead high-voltage transmission lines to form an optical fiber communication network on the transmission lines, this structural form combines the dual functions of ground wire and communication, and is generally referred to as OPGW optical cable.

　　1、 Central tubular OPGW

　　[Structural Characteristics]:

　　1. The design adopts stainless steel tube fiber optic unit and other metal wires twisted together at the same time.

　　2. Fiber optic cables placed inside stainless steel tubes can achieve optimal excess length.

　　3. The designed cross-section of the optical cable ensures its electrical performance, mechanical and physical properties, and thermal stability.

　　[Application Features]:

　　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-sections 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 than the aluminum tube structure; Moreover, stainless steel has low conductivity, high strength, excellent corrosion resistance, and provides good protection for optical fibers.

　　3. Filling the stainless steel tube with grease can prevent moisture or water from seeping in; Adjusting the excess length of the optical fiber can make the cable have good temperature characteristics.

　　4. High strength, low conductivity aluminum clad steel wire bears the weight and external load of OPGW; By utilizing the principle of charge skin effect, overload or fault short-circuit currents can be guided through the outer layer of good conductors, which is beneficial for the protection of optical fibers.

　　5. Fiber optic 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 ones. They also serve the dual functions of ground wires and communication.

　　6. The remaining length of the fiber optic cable can be controlled to ensure its ability to withstand high loads and large spans.
