DCR-2 Universal Service Drop Clamp (DCR strain wedge clamp )for 6-70 mm² Conductor
The DCR-2 strain wedge clamp is a highly versatile, professional-grade anchoring fitting custom-developed for securing, dead-ending, and tensioning overhead network distributions. Geometrically optimized to accommodate a wide linear span of conductor cross-sections from 6 mm² to 70 mm² , it delivers infrastructure contractors a highly adaptive method for managing low-voltage residential service lines, street lighting circuits, and self-supporting telecom cables.
Engineered to eradicate galvanic oxidation and line management field failures, the DCR-2 clamp incorporates an integrated PA6 Nylon insulated core and body that completely avoids atmospheric rust. Suspended by a heavy-gauge, flexible Stainless Steel wire rope (bail) , this self-adjusting dead-end assembly sustains a secure 2.5 KN rated tensile load capacity , ensuring reliable overhead distribution without scraping, crimping, or compromising the wire insulation sleeves.

Technical Parameters Description
Wide-Range Cross-Section Fit : The internal tapered channel is engineered with an advanced broad-groove configuration, permitting a single clamp model to securely lock conductors from 6 mm² up to 70 mm² , drastically reducing inventory stock complexity for contractors.
Monolithic Injection Molding Process : Manufactured using a state-of-the-art precision injection molding process , delivering seamless interior tracks and flawless wedge alignment that prevent physical friction damage on cable coatings.
Advanced All-Polymer Insulation Shield : Molded from a high-density PA6 Nylon matrix , the clamp body serves as an absolute dielectric safety barrier below 1 KV, eliminating phase-to-ground flashovers and electrical tracking during prolonged monsoons.
Marine-Grade Stainless Steel Bail : Outfitted with a high-flexibility Stainless Steel wire rope , providing supreme corrosion defense against coastal air while ensuring rapid mounting on standard closed/open drive hooks or pole brackets.
Broad Environmental Endurance Envelope : Thoroughly lab-tested to hold its complete mechanical load capacity without structural cracking under intense outdoor ambient temperatures ranging from -40 °C to +120 °C .
Product Features
🔒 Dynamic Conical Wedge Self-Locking : Utilizes an automated wedge-action design where natural cable pulling forces slide the internal blocks deeper into the tapered sleeve, maximizing holding efficiency without creating point-load pressure.
⚡ 100% Galvanic Corrosion Proof : The all-plastic PA6 body contains zero metallic outer shell parts, making it entirely immune to environmental rust, chemical acid rain, and electrical pitting in industrialized industrial sectors.
🛡 ️ Continuous Radial Stress Relief : The wide and smooth footprint of the interior insulated blocks spreads clamping force evenly across the wire segment, avoiding localized crushing forces and preserving internal cable strands.
🛠 ️ No-Tool Rapid Pole Deployment : Eliminates on-site reliance on heavy compression dies, hydraulic pumps, or specialized wrenches. A single lineman can slip, wrap, and lock the wire manually 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 , helping utilities drastically lower long-term asset replacement overhead.
