The ONZ series OPGW Preformed Tension Clamp is primarily used to install OPGW cables to tension towers/poles, corner towers/poles and terminal towers/poles. A complete set of OPGW tension clamp includes aluminum alloy or aluminum clad steel dead ends, structural reinforcement rods, support fittings and grounding clamps, etc.

Configuration & material: 

(1)Outer armor rod: steel wires

(2)Inner armor rod: steel wires

(3)Clevis thimble: hot galvanized cast steel

(4)Extension link: hot galvanized cast steel

(5)Anchor shackle: Hot dipped galvanized steel

(6)Parallel groove clamp

(7)Aluminum ground wire

(8)Bolt, nut and etc. 

Technical data:

(1)Stress can be distributed equally among the OPGW cable surface without stress centralization to protect OPGW cable. 

(2)It can have higher grip strength for the cable and can support higher tensile force when stress doesn’t exceed the optical cable’s side strength.

(3)The grip strength for the cable is not less than 95% of rated tension strength (RTS) of the optical cable, fully suitable for the installation of OPGW cable 

RTS: 60KN
