热浸镀锌钢 PH 延伸环 链节 电线杆五金延伸环

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.
