PAL1000 Heavy Tension Dead End Clamp(PAL1000 strain clamp wedge) for 25-35 mm² Cable
The PAL1000 strain clamp wedge is a high-grade infrastructure utility designed for terminating, anchor-fixing, and absorbing constant physical drift in overhead network frameworks. Configured to secure specific cable cross-sections from 25 mm² to 35 mm² , this high-performance line fastener delivers an ideal engineering answer for medium-span distribution links, rural power grids, and optical network connections.
Built to counter continuous structural sagging and line fatigue, the PAL1000 brings together a heavy-duty Die-Cast Aluminum Alloy outer cage and a non-conductive PA6 Nylon sliding core . Supported by a flexible, high-tensile Stainless Steel wire rope (bail) , this mechanical strain closure supports an excellent 12 KN rated tensile load capacity , locking the cable firmly without risking micro-deformations or peeling the conductor protective sheathings.

Technical Parameters Description
Targeted Mid-Size Section Gripping : The inner sliding groove is custom-calibrated for single or bundled lines from 25 mm² to 35 mm² , distributing constant radial friction across the line to optimize holding retention and block line drift.
High-Load 12 KN Rating : Reinforced to absorb up to 12 KN of permanent tensile stress , making this anchor fixture suitable for wider pole distances, line crossings, and geographic regions prone to windstorms.
High-Pressure Aluminum Casting : The structural alloy cage is built via an industrial die casting process , achieving an ultra-dense metallurgical structure with zero interior air pockets to resist long-term tension fatigue.
Dielectric PA6 Core Protection : The internal wedges are injection-molded using premium PA6 Nylon , creating an absolute insulation barrier below 1 KV that stops phase-to-ground leaks and surface tracking during seasonal rainstorms.
Broad Climatic Endurance Envelope : Fully certified to maintain its complete structural integrity and mechanical grip within an intense outdoor temperature range of -40 °C to +120 °C .
Product Features
🔒 Dynamic Anti-Slippage Wedging : Employs a physical wedge-action layout where increase in wire tension forces the internal PA6 blocks deeper into the tapered aluminum jacket, creating a continuous lock without creating point-load pressure.
⚙ ️ Hardened Die-Cast Outer Shield : The high-strength metal shell acts as a structural defense shield, completely absorbing side impacts and avoiding internal wedge deformation during fast on-site line stringing.
⚡ Certified Low-Voltage Insulation : Rated for circuits under 1 KV, the non-conductive PA6 wedges separate the conductors cleanly from the alloy frame, guaranteeing electrical tracking safety.
🛠 ️ One-Lineman Toolless Installation : Engineered for swift manual setup with no reliance on hydraulic compression heads, crimping dies, or wrenches. Linemen can snap and lock the line by hand, saving on-site assembly costs.
⏳ Multi-Decade Asset Lifecycle : The smart synergy of corrosion-proof aluminum alloys, stainless steel bails, and UV-stabilized resins ensures an outdoor active lifespan of 25+ years , cutting long-term grid maintenance budgets.
