The cable clamp has the advantages that the cable clamp has the grip strength not less than 95% of the rated tensile strength of the optical cable, the installation is convenient and rapid, and the construction cost is reduced. The ADSS optical cable is suitable for ADSS optical cable lines with span less than or equal to 100 meters and line rotation angles of less than 25 degrees.
The strain clamp is used for fixing a lead wire or a lightning conductor on a strain insulator string of a nonlinear tower, plays an anchoring role and is also used for fixing a stay wire of a stay wire tower. Strain clamps can be broadly classified into two types according to their structure and installation conditions. The first type: the strain clamp bears the whole tension of the lead or the lightning conductor, the clamp gripping force is not less than 90 of the rated tension of the installed lead or the lightning conductor, but the strain clamp does not serve as an electric conductor.
