HEAVY-DUTY COPPER LUGS
ROYSONS is a leading manufacturer and supplier of premium-grade Copper Lugs, headquartered at its registered office in Kolkata, West Bengal, India. Precision-engineered from high-conductivity electrolytic copper, our crimping lugs deliver seamless electrical connectivity and robust mechanical termination for power cables, transformers, switchgears, and industrial control panels. Designed to ensure low electrical resistance, maximum current carrying capacity, and superior corrosion resistance across high-voltage and heavy-duty industrial applications, ROYSONS Copper Lugs provide long-term reliability and effortless field crimping.
High Conductivity & Low Resistance
Manufactured from 99.9% pure ETP electrolytic grade copper to optimize electrical transfer efficiency, minimizing voltage drops and operational heat buildup.
Tin-Plated Surface Finish
Electro-tinned finish shields against atmospheric oxidation, chemical degradation, and galvanic corrosion for reliable long-term performance in humid and industrial environments.
Precision Crimping & Chamfered Entry
Engineered with smooth, internal bell-mouth or chamfered barrel ends to facilitate easy, damage-free conductor insertion and solid compression crimping.
ADVANCED PRODUCT CAPABILITIES
Maximum Electrical Conductivity
Manufactured from 99.9% pure ETP grade electrolytic copper, providing high current capacity and minimal resistance at high loads.
Electro-Tinned Corrosion Shield
Coated with a thick electro-tin plating layer to prevent surface oxidation, tarnishing, and degradation in aggressive operating environments.
Precision Crimping Barrel
Engineered with chamfered internal barrel entry for fast, seamless conductor insertion and uniform deformation during hex crimping.
Heavy Thermal & Mechanical Resistance
Seamless tubular construction resists cracking under high crimp pressures, heavy vibration, and extreme temperature fluctuations.
IEC & BS Industry Compliance
Fully compliant with international termination standards (IEC 61238 / BS EN 61238), ensuring broad compatibility with standard electrical gear.
