Earthwire Accessories for Transmission Lines

Our earthwire accessories support reliable grounding, lightning protection and mechanical stability across all transmission line voltage levels. The range includes suspension clamps, dead-end clamps, grounding connectors, bonding leads, U-bolts, vibration dampers and fittings for both galvanized steel earthwires and OPGW.

Each component is engineered for low electrical resistance, strong slip performance and consistent mechanical behavior under wind loading and thermal movement. Grounding and bonding fittings ensure stable fault-current paths and reduced risk of arcing. OPGW accessories are designed to prevent fibre compression and maintain safe bend radius during installation and operation.

All products are tested for mechanical load, galvanizing quality, resistance values and fatigue performance in accordance with IEC and IEEE standards. These accessories help utilities maintain effective lightning shielding, dependable grounding continuity and long-term stability of earthwire and OPGW systems.
