STB Tension Clamp for Fiber Cable for 2x16-25 mm² ABC Cable
The STB Tension Clamp for Fiber Cable is a high-reliability overhead network fitting developed exclusively for terminating, anchor-fixing, and tensioning two-core service drop wires and aerial bundled cables (ABC). Tailored precisely to support dual-conductor configurations from 2×16 mm² to 25 mm² , it provides an efficient and secure termination method for low-voltage residential connections, street lighting power links, and telecom drop wire lines.
Constructed to ensure safe and continuous grid operations, the STB clamp features an all-plastic PA6 Nylon insulated housing that eliminates chemical corrosion risk and galvanic interaction. Outfitted with an integrated, heavy-gauge Stainless Steel wire rope (bail) , this mechanical fastener maintains a stable 2.5 KN rated tensile load capacity , ensuring flawless service line routing without pinching or stripping the fragile outer cable sheaths.

Technical Parameters Description
Dedicated Dual-Core Alignment : The internal tapered channel is engineered specifically to grip 2×16 to 25 mm² parallel conductors , ensuring identical radial pressure is exerted on both cores to eliminate line slippage.
Precision High-Pressure Injection : The entire structural body is manufactured via a state-of-the-art injection molding process , delivering precise tolerances, flawless wedge alignment, and smooth interior paths that prevent abrasion.
Advanced Monolithic PA6 Insulation : Molded from a premium PA6 Nylon matrix , the clamp body serves as an absolute non-conductive safety barrier below 1 KV, completely eliminating the risk of tracking faults or phase leaks during heavy monsoons.
Marine-Grade Stainless Steel Loop : Features a highly flexible Stainless Steel wire rope that resists salt spray degradation and mechanical wear, allowing swift mounting onto universal eyelets, drive hooks, or pole brackets.
Rigorous Thermal Operation Limits : Extensively lab-tested to hold its full mechanical load without breaking or deforming within a wide climate window of -40 °C to +120 °C .
Product Features
🔒 Conical Self-Locking Wedges : Designed with an automatic wedging mechanism where increasing wire tension pulls the internal blocks deeper into the tapered sleeve, creating a tight manual lock without cable damage.
⚡ 100% Galvanic Corrosion Proof : The all-plastic PA6 body contains zero metal casing parts, making it impervious to atmospheric oxidation, acidic rain, and chemical corrosion in highly polluted industrial areas.
🛡 ️ Uniform Radial Stress Relief : The smooth and wide contact surface of the internal wedges distributes holding forces evenly across the cable section, eliminating localized crushing and protecting internal conductor strands.
🛠 ️ Toolless One-Man Pole Deployment : No hydraulic crimpers, compression dies, or wrenches are needed for installation. Field linemen can easily slip, wrap, and lock the wire manually, reducing construction times.
⏳ 25+ Years Maintenance-Free Asset : The engineered synergy of marine-grade stainless steel and heavily UV-stabilized polymer resins ensures a multi-decade outdoor lifespan, lowering long-term system maintenance costs.
