OPGW's metallic armor shields against electromagnetic interference and withstands high-current impacts from short circuits and lightning; ADSS has no metallic structure, eliminating the risk of induced current corrosion. Deployed together, they form dual-route communication channels that doubly guard against risks such as line icing, external damage, and grid faults, continuously ensuring uninterrupted transmission of core services including relay protection and data acquisition, with greatly enhanced communication stability.
