electric power fitting suspension string with yoke plate,suspension string
Composition: inner preformed wire, the outer pre-twisted wire, two sets of rubber clip block, two sets of cast aluminum shell and connecting fittings.

Uses: play a supportive role, the optical fiber composite overhead ground wire (OPGW) are hung on a straight line on the tower.

Features:a. Suspension OPGW cable with a larger contact area, stress distribution uniform, no stress concentration points, play better on cable protection, while enhancing the stiffness of cables hanging point location.
b. there is a better dynamic stress capacity, can provide sufficient grip strength (20% RTS) to maintain OPGW cables in the long run under the conditions of unbalanced load for safe operation.
c. Suspension of overhanging angle to meet the 30 ° ~ 36 °.
d. The structure coupled with flexible rubber clip block, enhanced self-damping to reduce wear and tear.
e. rounded end processing, increased corona voltage halo effect.
f. high-quality aluminum alloy material to enhance the mechanical properties of the clamp and corrosion resistance, significantly extended service life.

Technical requirements: meet the DL / T 766-2003 optical fiber composite overhead ground wire (OPGW) with the preformed fittings technical requirements and test methods.
Ordering Information:
a. According to the diameter of OPGW cable parameters such as selection of suitable Suspension. Dual-Suspension is mainly used for large cross rivers, high dro in the valley, heavy ice and other special places.
b. the number of configurations as follows: 1 set / line tower.
c. The inner clamp pre-twisted wire with OPGW outer spiral twist to the contrary, the standard configuration in accordance with OPGW outer stranding to the right-hand, such as a L, should be specified in the order contract.
 d. According to towers on the mount point, selec the appropriate link fittings (such as the U-screws, U-type hanging ring, UB-type, sandwich boards, etc.).
e. Clamp intensity is divided into 100kN, 120kN and so on.

OPGW Stranding pairs with the pre-Suspension Specifications Model Parameter table:
