Adss optical cable grounding wire
ADSS, or All-Dielectric Self-Supporting Cable, is a fiber optic cable that does not require any metallic components for grounding or support. Despite their shared objective of transmitting data, these cables diverge significantly in terms of structure, application, and installation methods. In contrast, OPGW cables serve a dual purpose: they function as both an optical communication line and a grounding wire for overhead power lines, showcasing. In modern power transmission systems, fiber optic cables do much more than carry data. Among all aerial fiber solutions, OPGW and ADSS stand out as the most widely used options.
