Line Fittings | NX-1 ~ NX-3 Wedge Type Guy Wire Strain Clamp for Tower Guying is a self-locking wedge-type guy wire strain clamp engineered for dead-ending and terminating galvanized steel stranded wires (GJ series) on distribution poles, transmission angle towers, and guyed masts. Features a high-integrity split-body malleable iron shell housing a high-friction precision-toothed wedge core that tightens automatically under applied line tension.
Guying and anchoring hardware plays a foundational role in maintaining structural stability, resisting lateral wind loads, balancing line turning moments, and securing overhead distribution poles and transmission towers against severe gale-force storms and extreme mechanical shock loads. Engineered for uncompromising tensile endurance and outdoor longevity, our guy wire fittings deliver dependable anchoring security across critical electrical power grid infrastructures.
Key Design & Performance Highlights:
- Material & Construction: High-grade hot-dip galvanized malleable cast iron / ductile iron housing (QT500-7) with carburized alloy steel toothed wedge core and Grade 8.8 galvanized clevis pin and cotter pin.
- Exceptional Tensile Strength: Heavy-duty structural design rated to achieve ≥ 95% of the ultimate tensile strength of high-tensile steel guy strands without structural slipping or deformation.
- Superior Corrosion Protection: Thick, uniform hot-dip galvanization conforming to ASTM A153, BS 729, and ISO 1461 delivers robust cathodic protection in harsh atmospheric, coastal, and underground soil environments.
- Engineered Fit & Reliability: Precision-contoured channels and smooth radii prevent strand cutting, fretting, or micro-cracking during long-term service under continuous mechanical tension.
- Industry Approvals & Standards: Manufactured in full compliance with GB/T 2314, DL/T 758, IEC 61284; ISO 9001 certified production with complete tensile failure load and zinc coating thickness test reports.
