Aluminum Stirrup Clamps with Bronze Bail
Overview
Our Aluminum Stirrup Clamps with Bronze Bail are precision-engineered mechanical connectors used in pole line hardware systems. Designed to combine the high strength of aluminum with the superior conductivity and corrosion resistance of bronze, these clamps ensure long-term performance in overhead power distribution applications. We are a leading manufacturer of Aluminum Overhead line clamps Aluminium Hotline clamps, Bronze Hotline clamps, Bronze Transformer spades etc. from our casting foundry in India. Our Aluminium Stirrup Bail Clamps are widely exported to USA and Latin America.
