The unique features and installation requirements of OPGW (Optical Ground Wire) cables are essential to understand for their successful deployment. OPGW cables are designed to be installed on transmission and distribution lines, providing both the functions of a ground wire and a communication network. The following key points outline the unique features and installation requirements of OPGW cables:
Unique Features of OPGW Cables
Dual Functionality: OPGW cables serve a dual function, acting as both a ground wire and a communication network, making them a versatile and efficient solution for power transmission lines
Environmental Protection: OPGW cables are designed to protect the enclosed fibers from environmental conditions such as lightning, short circuits, and mechanical loads, ensuring the reliability and service life of the fibers
Applicability: OPGW cables are mainly used for high-voltage transmission lines exceeding 110kV, with large distances between the towers, and are easy to maintain and solve line crossing problems
Structural Variants: OPGW cables come in different structural variants, such as center SST type, Al Clad SST type, Stranding SST type, and Al Clad PBT Tube type, each with its respective characteristics and applications
Installation Requirements of OPGW Cables
Proper Allotment and Installation: OPGW cables should be allotted correctly according to design requirements, and each tray of the optical fiber cable should be installed in the appointed part of the route and laid according to the chart operation file
Installation Preparation: The installation of OPGW cables requires the establishment of an OPGW installation and engineering plan, with the tension pay-off method being adopted to maintain suitable tension and prevent cable abrasion on the ground
Hardware and Accessories Installation: The installation of hardware and accessories, such as tension clamps, suspension clamps, vibration dampers, earth wires, downlead clamps, cable trays, and joint boxes, is a critical part of the OPGW installation process
Optic Fiber Splice and Testing: Optic fiber splicing and whole process testing are essential steps to ensure the integrity and performance of the OPGW cable network
Quality Control and Special Attention: Quality control measures and special attention during installation are crucial to guarantee the reliability and longevity of the OPGW cable system
So, the unique features and installation requirements of OPGW cables encompass their dual functionality, environmental protection, applicability to high-voltage lines, structural variants, and the need for proper allotment, hardware installation, and rigorous quality control during the installation process. Understanding and adhering to these requirements are essential for the successful deployment of OPGW cables in power transmission and communication networks.
