ALUMINIUM CABLE LUGS
ROYSONS is a premier manufacturer and supplier of heavy-duty Aluminium Cable Lugs, headquartered at its registered office in Kolkata, West Bengal, India. Precision-engineered from high-conductivity, electrical-grade EC aluminum tubing, our lugs deliver reliable termination for aluminum conductors across low to high-voltage electrical installations. Designed with corrosion-inhibiting barrel protection, Chamfered entry, and robust mechanical crimp strength, ROYSONS Aluminium Lugs ensure low electrical resistance, superior thermal stability, and long-term durability across industrial switchgears, transformers, and power distribution systems.
High Electrical Conductivity
Manufactured using pure EC grade aluminium to ensure low electrical contact resistance, high current-carrying capacity, and minimal power losses at termination joints.
Precision Barrel & Chamfer Entry
Engineered with an internal chamfer for seamless conductor insertion and uniform metal distribution during standard hex or circumferential crimping.
Oxidation & Thermal Resistance
Designed to resist surface oxidation, environmental corrosion, and high mechanical stress during severe electrical fault currents and thermal expansion cycles.
ADVANCED PRODUCT CAPABILITIES
High Electrical Conductivity
Precision-drawn from high-grade EC aluminium, ensuring optimal power transfer, minimal voltage drop, and low contact resistance across heavy electrical loads.
Heavy-Duty Mechanical Strength
Engineered with robust barrel wall thickness to resist pull-out forces, mechanical vibrations, and thermal stresses under peak short-circuit current conditions.
Chamfered Barrel & Secure Crimp
Features an internal chamfered entry design for swift conductor insertion and maximum metal contact during standard hexagonal or circumferential crimping.
Oxidation & Corrosion Protection
Treated with anti-corrosive passivation and optional anti-oxidation compound filling to prevent degradation and extend operational lifespan in harsh environments.
IEC & IS Standards Compliance
Manufactured in accordance with IEC 61238, IS 8309, and ISO quality standards to guarantee certified performance in switchgears, transformers, and industrial distribution panels.
