ADSS悬垂线夹/ Suspension for ADSS
内层护线条/ Structural Reinforcing Rod Component, 悬垂线夹（外层护线条）/ Outer Rods, U型挂环/Shackle, 直角环/ Clevis-Eye, 铝套壳/ Housing, 橡胶夹具（块）/ Insret
功能用途/ Function and Purpose
The clamp is used on supports to suspend ADSS.
产品特点/ Product characteristic
² Cables are finely protected because stress is equally distributed in large touching area without intensive stress pivot and stiffness is strengthened at the fixing point.
² The clamp has a slip load of more than 16%RTS of cable. It protects the safe operation of cable in the unbalanced loads condition for a period time.
² The end of the armor rod is processed with spherical surface treatment to increases corona inception voltage.
² Insret (EPDM) enhances the self-resistance and reduces friction.
² The materials of rod selected good quality aluminum alloy wire are against corrosion and improve the mechanical properties.
技术要求 / Technical Requirements
Compliant with DL/T 767-2003: Technical requirements and testing method of helical fittings for ADSS.
选型方法/ Lectotype Method
² According to the diameter, strength and application span of ADSS.
² Number of configuration: 1 set / Straight pole or tower
² Provides the connection type of the first fitting when connection with the pole or tower.
² Strength class: 20kN, 40kN, 60kN, 80kN.
During the installation of ADSS optical cable, attention must be paid to safety issues, of which personal safety is the most important, and all safety rules and regulations must be observed during construction. The hardware required for the installation of ADSS optical cable includes tension hardware for tension tower, suspension hardware for suspension, vibration whip, grounding wire, downlead clamp, etc. after the ADSS optical cable hardware is connected, the whole process index test shall be carried out. OTDR or light source and optical power meter are commonly used as test instruments. Test parameters include: total attenuation: meet the design requirements, 1310nm optical fiber should be less than 0.35db/km. Contact attenuation: it shall meet the design requirements, generally less than 0.05db.
