• 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.
