Suspension Clamp for OPGW cable

OPGW Suspension Clamps is used to fix the cable on the tower to support transposition.
  • product details

Product Instruction:

OPGW single suspension clamp is intended to connect OPGW on straight-line pole. The preformed rod clamp, with no concentrated stress, avoiding bend stress, plays a role to protect cable and assist reducing vibration. The whole set of suspension clamp contains: preformed rod, suspension clamp, and matching connection hardware. The clamp holding strength is over cable rated tensile strength for 10-20%, easy to install.

Function:
Mostly intended for OPGW in erecting straight-line pole, one pole for one set

Parameter:
Configure model by cable diameter 

Installation of OPGW Suspension Clamp

Components: outer preformed rod (dead end), structural reinforcing rod, anchor shackle, chain link, suspension clamp, rubber clamp, U-strap, ground wire clamp

Installation Steps:


1.   choose a hang point on pole, fasten connection fitting, make a suspension mark on cable as a winding center;


2.   take a single structural reinforcing rod, aim its installation mark at suspension mark made in step 1, wind separately for 2-3 pitches toward both ends;


3.   as former step, wind the 2nd structural reinforcing rod around cable; 


4.   complete winding the rest of structural reinforcing rod as above (keep both ends of preformed rod loose);


5.   complete winding both ends of preformed rod by hand


ensuring an even winding;


6.   split rubber clamp into 2 parts, one left, another right, aim its center at center color mark of structural reinforcing rod, enchase it outside the preformed rod, and fasten with tape; 

7.   take one outer preformed rod (dead end), make its center color mark aligned with rubber clamp center (make the surface of outer preformed rod (dead end) coincided with that of rubber clamp), wind outer preformed rod (dead end) on each side of rubber clamp for 2-3 pitches;   


8.   as step 7, wind the 2nd outer preformed rod on another side of rubber clamp;


9.   as former step, complete winding the all outer preformed rods in the same interval (not overlap, cross or distort it);


10.   wind both ends of preformed rod by hand;


keep it natural and level ;


11.   make suspension clamp center aiming at the center mark of the outer preformed rod (dead end), enchase suspension clamp outside preformed rod, leaving its lug upward;


12.   enchase U-strap onto suspension clamp from bottom to top, pat it in place by hand;


13.   connect suspension clamp to connection fitting, screw up and set pin up;


14.   connect pliers-clamp of ground wire, screw up;


15.   wear with ground terminal, screw up;


16.   installation is over.

Instructions:

1.   select suspension clamp model should depend on cable’s outer diameter, span, etc.;  

2.   in moving and installation, it shan’t be extruded or severely impacted to prevent from deformation;

3.   as matching parts for suspension clamp, preformed rod shall not be used repeatedly;  

4.   not change randomly the quantity and length of the suspension clamp parts, not be used repeatedly, it’s only be dismantled and reassembled once, that’s permanent installation;

5.   winding the preformed rod is required to operate by hand, not use any tools to avoid from damaging cable;

6.   if in doubt, please contact us.
