Copper Tube Terminals Heavy Duty BS-4579 Manufacturer
Daga Power Group is a leading Copper Tube Terminals Heavy Duty BS-4579 Manufacturer and reliable Copper Lugs Manufacturer based in Kolkata, delivering high-performance electrical termination solutions for industrial, commercial, and power distribution applications. With years of expertise in manufacturing precision-engineered copper terminals and cable lugs, we have established a strong reputation for quality, durability, and consistent electrical performance across West Bengal, Odisha, Bihar, Jharkhand, Chhattisgarh, and Assam.
Our Copper Tube Terminals are manufactured according to British Standard BS-4579 specifications using high-conductivity electrolytic copper tubes to ensure superior conductivity, high mechanical strength, and long service life. These heavy-duty copper terminals are widely used in switchgear panels, substations, transformers, electrical control systems, railway applications, power plants, and industrial electrical installations where secure and efficient electrical connections are essential.
Premium Quality Copper Tube Terminals Heavy Duty BS-4579
At Daga Power Group, we manufacture copper tube terminals that are designed to perform efficiently under heavy electrical loads and challenging operating environments. Our products are engineered with precision to provide reliable crimping performance, maximum current-carrying capacity, and vibration-resistant connections.
We use only premium-grade electrolytic copper with 99.9% purity to manufacture our terminals, ensuring low electrical resistance and excellent conductivity. The heavy-duty wall thickness of our tube terminals prevents deformation during crimping and ensures long-term reliability in critical power applications.
Our terminals are available in both bright copper and tin-plated finishes to provide enhanced corrosion resistance, especially for humid and coastal environments. The tin-plated coating improves oxidation resistance and increases the operational life of the terminals in demanding industrial conditions.
Manufacturing Process
- Raw Material Selection
Only high-purity electrolytic copper tubesconforming to BS EN standards are used to maintain excellent conductivity and mechanical strength. - Tube Cutting & Chamfering
Copper tubes are cut to exact lengths using precision cutting machines, followed by internal and external chamfering to prevent cable strand damage. - Annealing Process
Tubes are heat-treated (annealed) in controlled furnaces to improve flexibility and ensure reliable crimping without cracking. - Shaping & Forming
The terminals are hydraulically formed to BS-4579 specifications to achieve consistent barrel and palm geometry for accurate stud holes. - Drilling & Deburring
Stud holes are drilled precisely and deburred to eliminate burrs, ensuring smooth and uniform contact surfaces. - Tin Plating (Optional)
A high-quality tin coating is applied to resist oxidation and enhance corrosion protection, especially for coastal and humid environments. - Inspection & Testing
Every batch undergoes mechanical, dimensional, and electrical tests — including pull-out, conductivity, and visual inspection. - Packaging & Dispatch
Finished terminals are packed in protective, clearly labeled boxes for safe delivery across multiple regions.
