ADSS (All-Dielectric Self-Supporting) cables are designed for aerial deployment alongside power lines without metallic components. They are all-dielectric, meaning they contain no metal and are electrically insulated, which allows them to be installed near high-voltage lines safely without risk of electrical conduction or interference . Their self-supporting design uses aramid yarns or other non-metallic strength members to bear mechanical loads, eliminating the need for additional support structures . ADSS cables are primarily intended for data transmission and communication purposes.
Ground wires require electrical conductivity to safely carry fault currents or lightning strikes to the ground. Since ADSS cables contain no metallic elements, they cannot conduct electricity and therefore cannot perform grounding functions . Using ADSS as a ground wire would be unsafe and ineffective in protecting power systems from electrical faults or lightning.
OPGW (Optical Ground Wire) cables, in contrast, are dual-purpose: they combine optical fibers for communication with metallic components that provide electrical conductivity for grounding . OPGW cables are typically installed at the top of transmission towers, where they can act as a shield against lightning while simultaneously transmitting data. This dual functionality makes OPGW suitable for high-voltage power lines, whereas ADSS is limited to communication applications.
