NES-B1 Heavy-Duty Dead End Anchor Clamp(NES-B1 abc strain clamp) for 4x16-70 mm² ABC Cable
The NES-B1 abc strain clamp is a substation-grade tensioning utility specifically conceptualized for anchoring, supporting, and routing low-voltage overhead bundle systems. Purpose-built to handle multi-core ABC (Aerial Bundled Cables) ranging from 4x16 mm² to 70 mm² , it delivers high-performance mechanical strain relief for primary power distribution corridors and high-capacity industrial service drops.
Engineered to endure prolonged environmental stress, the NES-B1 integrates a die-cast aluminum alloy structural frame with an ultra-reliable PA6 nylon insulated wedge core . This self-locking layout provides a powerful 20 KN rated tension load holding efficiency without stripping or cutting through cable sheathings, offering utility contractors a reliable, failure-free link for high-tension line spans.

Technical Parameters Description
Heavy-Span 20 KN Tension Threshold : Specially reinforced to withstand a maximum breaking load of 20 KN , making this clamp suitable for larger line sags, long-distance pole spans, and regions with high wind velocity.
Multi-Core Bundle Configuration : Optimized with a wider wedge channel to uniformly securely hold 4x16 to 70 mm² bundle conductors , delivering balanced radial gripping force across all phases simultaneously.
Advanced Die-Casting Metallurgy : The exterior metallic block undergoes industrial Die-Casting processing , aligning the alloy matrix to ensure high tensile rigidity and maximum fatigue limits against permanent mechanical drift.
Dielectric PA6 Core Matrix : The sliding wedges are injection-molded using high-density Nylon PA6 , establishing an absolute dielectric barrier below 1 KV that prevents tracking faults and phase leakage under intense rain.
Rigorous Ambient Thermal Resilience : Certified to function continuously without mechanical degradation from -40 °C up to +120 °C , preventing winter structural embrittlement or tropical sun deformation.
Product Features
🔒 Dynamic Multi-Core Wedging : Employs an automatic sliding wedge logic where higher line drag pulls the internal PA6 wedges deeper into the aluminum shell, ensuring zero line slippage under severe weather loads.
🛡 ️ Structural Die-Cast Armor Cage : The high-strength aluminum casing acts as a protective shield that fully absorbs side impacts, preventing localized point-loads from damaging the core.
⚡ Full Galvanic Separation Safety : Rated for circuits ≤ 1 KV, the non-conductive PA6 wedges insulate the bundled conductors completely, eliminating short circuits and flashover hazards.
🛠 ️ One-Man Rapid Bolt-Free Assembly : Designed for tool-free, intuitive manual operation that cuts down deployment steps, saving power utility contractors valuable labor costs.
⏳ 25+ Years Maintenance-Free Asset : The calculated synergy of corrosion-proof alloy metals and weather-stabilized polymers guarantees an outdoor service life exceeding a quarter-century.
