The fiber optic dead end clamp (also globally recognized as a helical dead-end grip or preformed dead end fitting) is a specialized high-tensile pole line hardware engineered to anchor and secure overhead electrical conductors (such as ACSR/AAAC ) and fiber optic communication cables (ADSS/OPGW) to tension towers and poles. By incorporating a specialized helical design, the preformed rods wrap smoothly around the exterior of the conductor or cable, generating an evenly distributed, continuous gripping force. Unlike conventional bolted or hydraulic transmission clamps, this helical tension clamp delivers a superior holding efficiency exceeding 95% of the Rated Tensile Strength (RTS) while completely mitigating localized stress concentration. This ensures structural integrity against heavy wind loads, ice accumulation, and micro-vibrations in extreme outdoor grid environments.

Technical Specifications & Selection Guide
To assist EPC contractors, utility grid engineers, and international procurement managers in selecting the ideal aluminum-clad steel helical dead end assembly, please consult the following engineering standards:
- Material and Environmental Customization: Aluminum-Clad Steel (Alumoweld) Rods: Engineered with high fatigue limits and extreme tensile properties, making them the industry standard for OPGW, heavy-load ADSS, and high-tension conductor cross-overs.
- Aluminum Alloy Rods: Delivers optimized conductivity and elite corrosion resistance, ideal for low/medium voltage distribution lines and coastal environments.
- Galvanized Steel Rods: Cost-effective solution specifically designed for staying wires, earth wires, and guy wire anchoring.
- Outer Diameter (OD) Precision Requirement: Helical fittings are highly sensitive to the exact outer diameter of the conductor. When submitting an RFQ, please provide the exact cable/conductor specifications (e.g., ACSR Lynx, Hawk, Wolf) or its precise OD in millimeters rather than just the nominal cross-sectional area.
- Connecting Hardware Adaptability: We provide a comprehensive tension assembly. The dimensions of the accompanying hot-dip galvanized U-shackles, cotter pins, and bolts can be adjusted to flawlessly interface with your tower attachment plates.
Product Features & Advantages
- Zero Stress Concentration: The helical wrapping distribution ensures that the gripping force is allocated evenly over a widespread area, preventing point-source pressure and protecting the cable's core or internal optical fibers from micro-bending signal loss.
- Massive Mechanical Holding Capacity: Provides an unbreakable mechanical interlocking grip that confidently withstands over 95% of the conductor's Rated Tensile Strength (RTS) without slipping or scraping the outer strand layers.
- Elite Fatigue and Vibration Resistance: The flexible resilience of the preformed rods creates built-in damping properties that safely absorb and reduce Aeolian vibration and galloping caused by severe crosswinds, eliminating wire fatigue breaks.
- Tool-Free, High-Safety Installation: No heavy hydraulic compressors, specialized dies, or crimping tools are required. Line workers can rapidly apply the helical grips entirely by hand, minimizing structural safety risks and lowering field labor costs.
- 30+ Years Operational Lifespan: All steel link components feature a heavy hot-dip galvanized coating compliant with international durability standards, guaranteeing zero rusting in high-pollution or industrial sulfur environments.
