Application Areas
Overhead Transmission & Distribution Lines
Used as suspension clamps, tension clamps, or ball-eye connections in high-voltage power lines (AC/DC systems), suitable for extra-high voltage lines up to 1,100kV.
Substations & Switchgear
Connect composite insulators to busbars, circuit breakers, or disconnect switches, ensuring stable grounding and isolation.
Railway Electrification Systems
Secure catenary wires and overhead line equipment for high-speed rail and metro systems, withstanding vibrations and dynamic loads.
Renewable Energy Projects
Support offshore/onshore wind turbine earthing systems and solar tracker installations.
Industrial & Harsh Environments
Chemical plants, mining sites, coastal areas, telecom towers, and lightning protection systems.
Performance Advantages
✓ Longevity: Galvanization prevents rust in humid/coastal climates
