The successful installation of any aerial cable network relies heavily on the use of specialized hardware, among which tension clamps are indispensable. These devices are meticulously engineered to securely fix wires across challenging spans, ensuring stable cable laying over distances of tens or even hundreds of meters without excessive sagging. Unlike standard fasteners, high-quality tension clamps provide superior grip and stability, making them the optimal solution for deploying lines in areas where underground communication ducts are impractical or impossible to use.
On our platform, we offer advanced Wedge-Type Anchor Clamps—a new generation of hardware designed for maximum reliability in fiber optic deployment.
This next-generation tension clamp is specifically designed for the rapid fastening of self-supporting circular fiber optic cables. Thanks to its versatile design, this model is also fully capable of handling the suspension of various types of optical cables, including All-Dielectric Self-Supporting (ADSS) cables and modern FTTH (Fiber to the Home) drop cables.
Key Features and Technological Advantages
The design incorporates movable wedges that function without the need for additional tools. This allows installers to mount the cable quickly and efficiently onto support brackets or hooks without compromising the structural integrity of the cable itself. A removable "bow" (or bail) provides exceptional versatility, enabling the clamp to be attached to virtually any traverse bracket or suspension hook available on the market.
The active bow is constructed from high-tensile steel and treated with a protective anti-corrosive coating. This ensures the structure can withstand long-term operation under complex stress conditions and constant dynamic loads, making the clamp suitable for use even in geographically difficult zones.
A critical safety factor is the clamp body’s impressive breaking load capacity, which reaches up to 1.5 kN. This robust threshold ensures that both the cable and the connection remain intact during short-term overloads caused by external forces—such as falling tree branches or extreme weather events impacting the line supports.
Furthermore, this Optical Suspension Clamp excels at gripping delicate FTTH cables. Its innovative wedge design features multiple precision-engineered spikes strategically positioned to grip the cable jacket firmly while preventing damage to the dielectric sheath and internal fibers.

Upgraded Design and Performance
The evolution of this tension clamp focuses on enhancing installer convenience and operational safety:
-
Captive Components: The wedges are now completely captive within the assembly. This prevents parts from being dropped or lost during installation or unplanned maintenance work at height.
-
Exceptional Strength: Rigorous testing with fiber optic cables has confirmed that the clamp can withstand short-term tensile loads of up to 1.5 kN without failure.
-
Premium Materials: We have significantly upgraded the raw materials used in manufacturing, resulting in a product with superior UV resistance, weatherproofing, and mechanical durability.
-
Broad Versatility: The clamp is engineered to accommodate a wide range of cable diameters. It securely holds round cables with a diameter of 3–8 mm and is also compatible with figure-eight ("8") style cables.
