PA Series Anchoring Clamps (including PA1000, PA1500, and PA2000) are heavy-duty mechanical fittings engineered to anchor and secure low-voltage Aerial Bundled Conductor (A.B.C.) networks utilizing an insulated neutral messenger system. Available in various mechanical tensile load capacities to match specific utility demands, these wedge-type dead-end clamps provide an uncompromised termination at end poles, angled routing positions, and high-tension dead-end spans without damaging the messenger’s insulation layer.

Features
Tool-Free Self-Tightening Wedges
Features an intelligent conical wedge design that automatically clamps tighter as the line tension increases. The self-adjusting sliding blocks ensure a fast, tool-less, and secure overhead installation.
Versatile Mechanical Load Ratings
Optimized in multiple configurations to meet diverse utility span lengths and tensile needs: PA1000 for standard loads, PA1500 for heavy-duty main trunklines, and PA2000 for ultimate high-tension distribution runs.
Stainless Steel Bail Flexibility
Equipped with a flexible, high-tensile stainless steel wire bail featuring a protective movable wear piece. This allows seamless coupling to bracket hooks, crossarms, or eye bolts at various installation angles.
Insulation-Safe Protection
The internal gripping wedges are precision-molded from specialized glass-fiber reinforced polymer, preventing line core slippage while completely preserving the integrity of the insulated conductor jacket.
Implementation Instructions
Step 1: Wedge & Cable Alignment
Open the plastic body casing and slide back the internal insulating wedges. Position the insulated neutral messenger conductor inside the designated parallel channel between the wedges.
Step 2: Bracket Hook Engagement
Loop the flexible stainless steel wire bail through the overhead pole bracket or anchoring hook, securing the plastic wear saddle onto the hook interface to prevent localized abrasion.
Step 3: Mechanical Tensioning
Pull the conductor down line to introduce initial mechanical sag tension. Forcefully slide the wedges forward into the conical body to initiate the self-locking grip before fully releasing the line wire.
Step 4: Dead-End Deadweight Safety Operation
Although the PA Series clamps utilize fully insulated internal wedges and can be handled adjacent to live networks, linesmen must ensure that proper cable pulling equipment (come-along clamps and pulling grips) is deployed to take up the line’s full deadweight tension before securing the final messenger inside the wedges.
Industrial Engineering & Standards
Rigorously tested and certified to endure decades of prolonged mechanical stress and atmospheric exposure in global infrastructure:
- Premium Material Compositions: The outer body is die-cast from high-strength, weather-proof, and corrosion-resistant aluminum alloy, combined with a UV-stabilized engineered thermoplastic wedge core.
- Rigorous Compliance: Fully qualified according to the supreme performance, climatic aging, and mechanical tension criteria of the NF C 33-041 and EN 50483-3 overhead utility standards.
- Zero Cable Damage: The soft yet firm clamping curvature ensures no concentrated stress fields or point loads, meaning zero risk of cable core necking or dielectric breakdown.
