ADSS-PTC-02 Preformed Tension Clamp for ADSS Cable

As a primary infrastructure buyer managing regional aerial fiber deployments, finding dead-end hardware that delivers full tensile termination without damaging the ADSS sheath is critical. We procured FirstFiber Technologies' ADSS-PTC-02 Preformed Tension Clamps for our 12.3 to 12.9 mm cable spans. The 20 KN rated gripping force easily handles high tension across dead-end structures during peak ice and wind loading events. Because the preformed helical wires distribute clamping force along a wide contact length, our post-installation OTDR testing showed zero microbending loss or signal degradation. At a $9 reference price per unit, it provides enterprise-grade dead-end reliability at a very competitive price point.

Precise cable outer diameter matching is vital for dead-end tension hardware to ensure non-slip holding performance under heavy line tension. FirstFiber's ADSS-PTC-02 line stands out due to its granular diameter bracket options, ranging from 8.6 mm to 14.6 mm, with custom sizing supported up to 18.7 mm. We opted for the 11.5 to 12.2 mm model (1.35 kg unit weight) for our 72-core ADSS cable build. The pre-shaped helical design allows tool-free, manual installation on strain towers, which greatly reduced field labor time for our lineworkers. The mechanical grip retention has proven rock-solid across months of extreme outdoor exposure.

Dead-ending ADSS optical fiber cables along high-voltage transmission corridors requires robust, high-strength hardware. The ADSS-PTC-02 tension clamp delivers a uniform 20 KN gripping force across all standard cable sizes. We deployed the 13.8 to 14.6 mm variant (weighing 1.57 kg) for our heavy-jacketed, long-span dead-end locations. The graduated weight specifications (starting from 0.88 kg for 8.6 mm up to 1.57 kg for 14.6 mm) accurately reflect the engineered wire length needed for larger cable diameters. It is an exceptionally engineered, reliable dead-end clamping solution for carrier-grade utility fiber networks.
