Hot Dip Galvanized Steel PH Extension Ring Chain Link Electric Pole Line Hardware Extension Ring

Jiujin Electric Power’s PH Extension Ring is engineered for reliable performance in electrical distribution networks. Manufactured from high-strength carbon steel (Q235B) with a thick hot-dip galvanized coating (≥85µm), this extension ring offers exceptional corrosion resistance and durability in harsh outdoor environments. The PH-type design ensures easy installation and secure connections between chain links, insulators, and other pole line hardware. The smooth, rounded edges prevent damage to connected components while maintaining structural integrity under mechanical loads. Ideal for extending insulator strings, adapting hardware configurations, and creating flexible connection points in transmission and distribution systems.
