U Shackle Ring Power Link Fittings

U Shackle Ring Power Link Fittings

The U Shackle Ring is a highly versatile general-purpose connecting fitting for transmission and distribution lines. It is primarily used to connect insulators, strain clamps, or suspension clamps to tower structures for securing conductors. Formed from round steel into a U-shape, this fitting features simple construction, high strength, and installation without specialized tools. It is one of the most widely used connecting components in overhead transmission lines, urban distribution networks, substation projects, and railway power supply systems. Common models include U-7, U-10, U-12, U-16, and U-20, covering voltage levels from 10kV to 500kV.

Description

 Materials and Manufacturing

 

The U Shackle Ring is manufactured from high-quality round steel through hot bending, with a complete hot-dip galvanized finish. The U-shaped bend is free of cracks and wrinkles, ensuring even stress distribution under conductor tension. Pin hole positioning is tightly controlled for smooth pin engagement with matching hardware. The galvanized coating covers both exterior and interior surfaces for reliable corrosion resistance in various outdoor environments. The fitting can be used individually or two units can be connected in series for extended length. Production strictly follows GB/T 2314 and GB/T 2315 standards, with full quality control from raw material receipt to finished product dispatch.

 

 Production Efficiency

 

As a high-volume general-purpose component, the U Shackle Ring's production efficiency and dimensional consistency are critical for supply capacity. Hebei Tongchuang Power Fittings Co., Ltd. has established a dedicated production line equipped with automatic bar cutters and hydraulic thread rolling machines, achieving semi-automated processing from round steel cutting to bending and pin hole drilling. Raw material steel is verified through material certificates and spectrometer analysis upon receipt. Every bent unit undergoes 100% visual inspection with focused checks on cracks at the U-shaped bottom and pin hole positioning. Each batch is subject to destructive load testing at standard sampling rates. The company is a nationally recognized high-tech enterprise with quality and environmental management system certifications.
