The strain clamp is used for corner turning, connection and connection of terminals. The spiral aluminum clad steel wire has extremely strong strain strength and no concentrated stress, and plays a role in protecting and assisting vibration reduction of the optical cable. The whole set of optical cable strain fitting comprises: the tension-resistant preformed armor rods are connected with hardware fittings in a matched mode. 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. The wire clamp can be detached after the wire is installed and used additionally. The cable clamp comprises a bolt type strain clamp, a wedge type strain clamp and the like. The second type: the strain clamp can bear all the tensile force of the conducting wire or the lightning conductor and can also be used as a conductor. Therefore, once the wire clamp is installed, the wire clamp can not be disassembled any more, and the wire clamp is also called a dead wire clamp. Because of the electric conductor, the installation of the wire clamp must be carefully carried out according to the regulations related to the installation operation rules;
at present, the hydraulic tension clamp for the aluminum-clad steel strand is rigid in structure and particularly low in connection strength, so that the tension clamp for the hydraulic aluminum-clad steel strand is provided by the inventor by integrating various factors.
