Product Desciption

Description:
Composition: inner twisted wire, the outer twisted wire, thimble, PD-type clevis, U-type hanging ring.
Purposes:  to afford the whole tension, make the optical fiber composite overhead ground wire (OPGW) connect to tension tower.
Features:  a. uniform stress distribution, no stress concentration points, well protect fiber optic cable.
b. under the premise of not more than the lateral compressive strength of fiber optic cable the fiber, the clamp have greater holding power, able to withstand greater tension.
c. The holding force not less than fiber optic cable rated tensile strength (RTS) 95%, not damage OPGW cable at the same time.
d. high-quality aluminum-clad steel material, improve the mechanical properties of the clamp and corrosion resistance.
Technical requirements: meet the DL / T 766-2003 optical fiber composite overhead ground wire (OPGW) with the preformed helical fittings technical requirements and test methods.
Ordering Information:
a. According to OPGW cable rated tensile strength and diameter to select the appropriate Clamp.
b. the number of configurations: one set / Terminal Tower (including gantry); 2 sets / Tension tower.
c. The lay direction of inner twisted wire is opposite with lay direction of the outer twist wire, the standard configuration: Lay direction for OPGW outer twisted wire is right, If left, it should be specified in the order contract.
d. The clamp afford a full tension, it was proposed to use one-time.
e. provide the model type for the first tower connected with the fittings.
f. Clamp strength is divided into 70kN, 100kN, 120kN and so on.
