STC 4-Core Insulated Tension Clamp(STC adss clamp) for 4x16-25 mm² ABC Cable
The STC adss clamp represents a highly specialized, lightweight utility fitting custom-engineered for securing, tightening, and terminating four-core overhead cluster networks. Tailored specifically to accommodate parallel multi-conductor setups from 4×16 mm² to 25 mm² , it provides grid contractors with an ultra-efficient method for anchoring low-voltage residential service drops, secondary distribution lines, and multi-strand telecom cables.
Developed to eliminate network downtime and metallic wear, the STC clamp incorporates an all-polymer Nylon PA6 insulated unibody housing that avoids corrosion and atmospheric rust. Integrated with a heavy-gauge, flexible Stainless Steel wire rope (bail) , this self-locking dead-end assembly sustains a continuous 2.5 KN rated tensile load capacity , ensuring reliable cable anchoring without compressing or skinning the conductor insulation.

Technical Parameters Description
Four-Phase Balanced Gripping : The inner tapered channel is geometrically calibrated to anchor 4×16 to 25 mm² parallel conductors , ensuring identical radial friction is distributed to all four cores simultaneously to prevent line offset.
Monolithic Injection Molding Process : Manufactured using a state-of-the-art precision injection molding process , delivering seamless interior tracks and absolute dimensional tolerances that prevent friction scratches on cable sleeves.
Advanced All-Polymer PA6 Insulation : The entire main body is molded from high-density Nylon PA6 with UV stabilizers , creating an absolute dielectric barrier below 1 KV that prevents phase-to-phase shorts and surface electrical tracking under severe rain storms.
Marine-Grade Stainless Steel Bail : Outfitted with a high-flexibility Stainless Steel wire rope , providing supreme corrosion defense against marine environments while ensuring rapid mounting on standard drive hooks, pole brackets, or wall eyes.
Broad Climatic Endurance Envelope : Fully certified to maintain its complete mechanical load rating and shape integrity under intense outdoor operational temperatures ranging from -40 °C to +120 °C .
Product Features
🔒 Auto-Sinking Conical Locking : Features a smart sliding wedge logic where increased wind or ice pulling force automatically draws the inner blocks deeper into the tapered body, maximizing grip without causing conductor deformation.
⚡ 100% Galvanic Corrosion Free : The all-plastic Nylon PA6 outer chassis contains zero metal parts, making it entirely immune to environmental rust, chemical acid rain, and electrical pitting in industrialized grid sectors.
🛡 ️ Continuous Stress Relief Surface : The wide contact footprint of the interior insulated blocks spreads holding stress uniformly across the line segment, avoiding localized crushing forces and preserving cable life.
🛠 ️ No-Tool Rapid Pole Deployment : Eliminates on-site reliance on heavy compression dies, hydraulic pumps, or wrenches. A single lineman can slip, secure, and anchor the cable by hand in seconds, cutting deployment costs.
⏳ Multi-Decade Low-Maintenance Asset : The calculated integration of weatherproof stainless steel and highly stabilized resins guarantees an active service life of 25+ years , drastically reducing utility asset replacement costs.
