BIMETALLIC CABLE LUGS
ROYSONS is a premier manufacturer and supplier of high-performance Bimetallic Cable Lugs, headquartered at its registered office in Kolkata, West Bengal, India. Friction-welded using high-purity EC Grade Aluminium and Electrolytic Copper, our bimetallic lugs provide a seamless transition when connecting aluminium conductors to copper busbars or terminals. By eliminating galvanic corrosion and minimizing contact resistance, ROYSONS Bimetallic Lugs deliver maximum conductivity, mechanical reliability, and long-term stability across low to high-voltage industrial installations.
Friction-Welded Technology
Engineered via molecular-level friction welding between high-purity aluminium and copper to guarantee flawless joint integrity, low resistance, and zero risk of joint failure.
Galvanic Corrosion Prevention
Eliminates electrochemical action and bi-metallic oxidation at the connection joint, ensuring safe termination of aluminium conductors directly onto copper busbars.
Precision Barrel & Chamfer Entry
Designed with internal chamfering for smooth conductor insertion and capped/capped-barrel options prepopulated with anti-oxidant joint compound for maximum thermal stability.
ADVANCED BIMETALLIC CAPABILITIES
Friction-Welded Molecular Joint
Engineered via state-of-the-art friction welding to bond EC Grade Aluminium and Electrolytic Copper, ensuring maximum joint strength, zero voids, and seamless power transfer.
Galvanic Corrosion Prevention
Eliminates electrolytic reaction and chemical oxidation at the transition point when connecting aluminium conductors directly to copper busbars or switches.
Chamfered Barrel & Anti-Oxidant Paste
Designed with an internal chamfer for smooth conductor insertion, pre-filled with high-grade anti-oxidation paste to protect against internal corrosion.
High Mechanical & Thermal Resistance
Precision-manufactured with heavy-duty walls capable of enduring thermal expansion cycles, high fault currents, and severe mechanical pull-out forces.
IEC & IS Standards Compliance
Manufactured in strict adherence to IEC 61238, IS 8309, and ISO quality specifications for guaranteed performance across utility power systems and industrial switchgears.
