Key Selling Points
- High-Precision Forged Construction: Made from high-grade carbon steel, hot-forged for full structural integrity, ensuring superior tensile strength and resistance to fatigue under dynamic line loads.
- Secure Triple Locking System: Equipped with a precision-machined pin, double hex nuts, and a stainless steel cotter pin to eliminate loosening caused by vibration, wind, and thermal cycling.
- Heavy-Duty HDG Protection: Uniform hot-dip galvanized coating (≥86μm) provides long-term corrosion resistance, meeting ISO 1461 standards for harsh outdoor, coastal, and industrial environments.
- Standardized Compatibility: Designed to comply with GB/T 2314 and IEC 61284 standards, matching common insulator strings, tower cross-arms, and clevis fittings for seamless installation.
Product Description
The U-Shackle (U-Type Link) is a foundational connection fitting in overhead transmission line systems, engineered to link insulator assemblies, suspension clamps, and tension clamps to tower cross-arms or anchor plates. Its U-shaped design allows flexible yet robust connection across various tower attachment points, with a range of opening widths (C) and pin diameters (M) to match different hardware configurations. Each unit undergoes strict mechanical testing, including minimum breaking load verification and salt spray corrosion testing, to ensure compliance with global utility standards. The double-nut and cotter pin assembly provides redundant safety against accidental disengagement, making it ideal for both distribution and transmission line applications
