Tension Set

The tension set features a helical preformed structure. It is used for anchoring optical cables on terminal and angle towers. It can transfer axial tensile load and apply uniform radial clamping force on the cable to protect optical fibers from damage.

Product Introduction:

The dead-end set is composed of components including U shackle, PD link, thimble clevis, dead-end component, structural reinforcing rods, parallel groove clamp and grounding wire set. The inner helical preformed rods and dead-end component bear axial tensile load, distributing radial compressive force evenly on the contact surface of the optical cable to reduce impacts on the cable core and internal optical fibers. Both inner and outer surfaces of the armor rods are coated with silicon-carbide to improve damping performance.

Core Advantages:

Reliable Tension Transmission: The minimum holding strength of the dead-end set is no less than 95% rated tensile strength of the optical cable, realizing stable cable anchoring and reliable transfer of axial tensile load.
Excellent Protection Performance: Helical armor rods evenly disperse radial compressive force, mitigating adverse impacts on the cable central core and internal optical fibers to keep optical fibers intact.
Damping and Anti-fatigue Performance: The inner and outer surfaces of armor rods are coated with silicon-carbide to enhance damping capacity. It delivers outstanding anti-fatigue property and adapts to long-term vibrating service conditions outdoors.
Convenient Installation: The dead-end clamp can be assembled without special tools for simple and efficient field construction.
