Plastic Body 2-Core Service Anchoring Clamps are high-efficiency, fully insulated overhead fittings engineered to dead-end and secure 2-core insulated service lines branching from distribution networks to end-consumer premises. Molded from high-impact, weather-proof engineering thermoplastics, this lightweight clamp simultaneously grips both insulated cable cores via a self-tightening wedge system. It delivers a permanent, high-tension termination at service poles or residential walls without requiring linesmen to strip the outer cable insulation.

Features
100% Insulated Plastic Enclosure
Fabricated completely from high-grade structural engineering polymers. This zero-metal housing layout guarantees absolute dielectric isolation, completely eliminating current tracking, flashover hazards, and atmospheric rust in coastal salt-spray or industrial smog regions.
Symmetrical 2-Core Parallel Groove
Features an integrated internal wedge core precisely molded with two parallel wire channels. This structural matrix provides balanced, symmetrical gripping pressure over both insulated conductors, preventing cable slippage or core flattening.
Stripping-Free Wedge Locking
Explicitly calibrated for direct implementation on unstripped insulated service drops. As the dynamic line span load increases due to wind shear or sagging, the wedges automatically advance deeper into the conical body to tighten their hold safely without piercing the outer jacket.
Resilient High-Fatigue Wire Bail
Equipped with a highly flexible, high-tensile stainless steel wire loop or a non-conductive composite bail. This durable loop smoothly dampens environmental mechanical vibrations while ensuring rapid, tool-free attachment over standard pole hooks or drive pins.
Implementation Instructions
Step 1: Parallel Core Seating
Do not strip the cable insulation jacket. Open or pull back the internal plastic sliding wedges from the clamp housing, and lay the 2-core insulated cable bundle parallel inside the designated double-slot channels.
Step 2: Bracket Hook Attachment
Advance the wedges manually into the conical body sleeve to establish the initial grip. Slip the flexible wire bail loop smoothly over the designated pole bracket, wall-mounted hook, or consumer box eyelet.
Step 3: Self-Tightening Sag Lock
Draw the service cable bundle outward to achieve the calculated network line sag profile. Once the mechanical span weight is transferred to the clamp, the self-tightening wedges will instantly lock into a permanent holding state.
Step 4: High-Safety Residential Drop & Live-Line Operations
Because both the outer housing and the internal gripping wedges are molded from premium non-conductive polymer matrix, these 2-core plastic clamps are exceptionally safe for installation in close proximity to live lines (hot-line handling). However, prior to final line release, linesmen must visually confirm that the cable insulation jacket is free from raw punctures or core exposure to ensure total watertight safety.
Industrial Engineering & Standards
High-grade fully insulated miniature tension clamps verified to sustain decades of continuous physical strain in global distribution grids:
- Premium Material Composites: Molded from glass-fiber reinforced, UV-stabilized engineered thermoplastics with high thermal stability, preventing dynamic structural fatigue, micro-cracking, or structural creep.
- Rigid Utility Standard Compliance: Thoroughly batch-tested and certified to meet or exceed the performance benchmarks of NF C 33-042 and EN 50483-3 standard specifications for low-voltage aerial accessories.
- Zero Thermal Degradation: All polymer housing shells and internal wedge components maintain exceptional dimensional stability and mechanical elasticity across an expansive operational thermal window, resisting both extreme freeze and intense tropical UV heat waves.
