Tension Dead-end for OPGW

  • Product Model: OPGW-T

Product Description:

OPGW tension clamp is intended to turn angle, continue, and connect terminal. Helical aluminum clad steel rod, with great tensile strength and no concentrated stress, may play a role to protect cable and assist reducing vibration. The whole set of cable tension hardware contains: outer preformed rod (dead end), structural reinforcing rod, and matching connection hardware. Clamp holding strength is no less than 95% of rated tensile strength, easy and quick to install, reduce construction cost.


The hardware is mainly intended to bear axial stress and distribute uniformly radial stress, so as to offer a safe and reliable holding strength on the premise of not damaging cable (mostly used in turning angle, continuing pole and terminal pole)

15.   Installation is over.



 1.   Select tension clamp model according to cable’s outer diameter, rated tensile strength (or span), etc.;

 2.   In moving and installation, it shall be avoided from extrusion, severe impact, and deformation;  

 3.   As matching component, it shall not be changed randomly, and not be used repeatedly, it may be disassembled and reassembled only once, which is a permanent assemble, shall not be disassembled once again;  

 4.   In winding process, to operate by hand is required, any tool shan’t be intended to avoid from damaging cable;  

 5.   If in doubt, please contact us.  


If you have inquiry and suggestion, don’t hesitate contact us. It’s our pleasure.
