U-Shaped Shackle Connecting Fitting

The U-shaped shackle is a core connecting component used in power transmission and distribution lines. It is widely employed in overhead power lines and substation structures to facilitate articulated connections between insulators, guy wires, and various other hardware fittings, serving as an essential load-bearing connector in power systems.

These U-shaped shackles are forged from high-quality carbon structural steel, resulting in a dense, solid structure free from defects such as sand holes or cracks. Each unit comes complete with a bolt, flat washer, anti-loosening nut, and cotter pin; once installed, the cotter pin locks the assembly in place, effectively preventing the bolt from loosening or detaching. The entire component undergoes hot-dip galvanizing for corrosion protection, offering high strength, excellent resistance to rust and aging, and stable mechanical performance. They are capable of withstanding both static loads and transient impact loads during line operation, while resisting corrosion from outdoor elements-such as rain, humid air, and saline or alkaline environments-thereby extending the product's service life. They are well-suited for use in challenging environments, including high-altitude, coastal, and mountainous regions.

We offer a comprehensive range of specifications, including national standard (GB) models such as U-7, U-10, U-12, U-16, and U-20, designed to meet various load-bearing requirements. Manufactured in strict accordance with the GB/T 2314 standard for power fittings, these shackles are easy to install. Their flexible U-shaped design allows for multi-angle rotation, which minimizes bending stress on the hardware and reduces the risk of stress concentration. Furthermore, they are simple to disassemble and maintain, significantly enhancing efficiency during power infrastructure construction. Customization options are also available to meet the specific needs of domestic projects and international exports. As a fundamental connecting component, the quality of a U-shaped shackle is directly linked to the safety of the power line; therefore, we strictly control every stage of the production process to ensure stable, reliable quality that provides a solid foundation for power engineering projects.
