  • OPGW AC/SX

    This handbook is formulated on IEEE 1138-2008 and IEEE 524-1992 etc.

    OPGW has two functions:  electric aerial ground wire and fiber communication.

    It is constituted of AS wire, AA wire and stainless steel tube op-unit. The installation rules of OPGW are almost the same as the engineering and installation modes of traditional aerial electric power wire, referring to electric power company's aerial transmit circuitry installation skills, management and other related files. In order to guarantee the installation of OPGW and avoid the waste of personnel and material resources, we compile this handbook as the reference, not instead of any other manufacturers' installation instructions.

    OPGW is usually installed on the top of pole of the electric power aerial wire. The following disadvantages should be considered: vibration caused by wind, hurricane, ice thickness, unsteady operation caused by temperature, and possible thunder attack, short circuit ere. Therefore, detailed engineering program should be formulated according to different structures of OPGW and specific route conditions. According to design requirement, OPGW should be allotted correctly; every tray of optical fiber cable should he installed in the appointed part of route and should be laid according to engineering chart operation file.

  • OPGW AC/SX


    The following outline describes the OPGW cable information required to select proper cable attachment hardware and accessories. Most of the cable information can be found in the cable manufacturer's specification – it is recommended that this information be gathered along with the information about the customer’s cable system. Submit this information to technical support to verify proper application.

    • CABLE INFORMATION REQUIRED for DEAD-ENDS AND SUSPENSIONS:
      • CABLE SPECIFICATIONS/ Cable Specification Sheet Data
        • Cable Diameter: Overall outer diameter of the OPGW.
        • Cable Construction Strand Configuration: Lay Direction of outer wire strands, Distribution and Location of individual strand materials in a cross-section, Number of strand layers.
        • Rated Breaking Strength
        • Fault Current
      • CABLE SYSTEM
        • Maximum Vertical Load at Hardware Attachment
        • Line Angles


    In addition to the outline above, other products for OPGW applications require further information as listed below.

    • ADDITIONAL INFORMATION FOR OTHER HARDWARE ACCESSORIES:
      • Splice Closures, Closures, and Domes
        • Fiber Count
        • Fiber Type
        • Fiber Optic Element Configuration
        • Type of Buffer Tubes (plastic or stainless steel)
        • Core construction (Solid, Aluminum Tube, Aluminum Channel),
      • Spiral Vibration Damper
        • Span Lengths
        • Final Tension at the Average Annual Minimum Temperature (AAMT)
        • Terrain
      • FITTINGS (Y-Clevis, Clevis Eye, Yoke Plates), Ground Wire, Downlead Cushions, Cable Storage
        • Interface at structure
        • Type of Structure (Wood Pole, Concrete, Steel, Lattice Tower)
        • Ground Wire Material, Bonding Material

    HARDWARE TESTS:

    The IEEE 1138 Test Standard for OPGW includes a series of tests that require suitable hardware to demonstrate system performance. System tests include Tensile Strength, Vibration Test, and Galloping Tests among others. System tests require dead-ends and suspensions that can survive the test parameters and prove cable/hardware compatibility. For multi-layer strand cable construction, special recommendations may be required after review.
