Line Fittings | NUT-1 ~ NUT-3 Adjustable UT Type Guy Wire Clamp (Stay Wire Strain Clamp) is an adjustable bolted UT-type guy wire clamp engineered for securing, anchoring, and tension-adjusting steel guy strands (GJ series / stay wires) on utility poles and overhead transmission towers. Utilizing a high-strength hot-dip galvanized U-bolt threaded adjustment rod combined with a heavy-duty malleable cast iron wedge clamp body, it allows precise field adjustment of guy wire sag and 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-strength hot-dip galvanized malleable cast iron body (KTH350-10 / QT450-10) with Grade 8.8 hot-dip galvanized steel U-bolt, adjusting hex nuts, and locking washers conforming to ASTM A153 / ISO 1461.
- 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, BS 3288; ISO 9001 certified production with complete tensile failure load and zinc coating thickness test reports.
