Copper Tube Terminals Heavy Duty BS-4579 Manufacturer
Product Description
Daga Power Systems is a leading manufacturer of Copper Tube Terminals Heavy Duty BS-4579, offering premium-quality electrical terminations that meet the stringent requirements of British Standard BS-4579 (Part 1). These terminals are manufactured from high-conductivity electrolytic copper tubes, ensuring superior electrical and mechanical performance for heavy-duty industrial, electrical, and power transmission applications.
Our Copper Tube Terminals (BS-4579) are designed for reliability, durability, and easy crimping — providing long-lasting and efficient connections in control panels, switchgear, substations, transformers, locomotives, and heavy electrical installations across Kolkata, West Bengal, Odisha, Bihar, Jharkhand, Chhattisgarh, and Assam. Each terminal undergoes stringent testing and precision manufacturing to deliver optimum conductivity, perfect fit, and maximum current-carrying capacity.
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.
