Professional Manufacturer of Tubular Busbar Weight

Aluminum tubular busbars are lightweight, high-conductivity conductors manufactured by specialized companies such as HTS-Alu, Hydro, Chalco, Promet AG, and HC Aluminum, offering optimized weight and mechanical strength for power distribution systems.

Overview of Tubular Busbars

Tubular busbars are hollow, tube-shaped conductors primarily made from high-purity aluminum or aluminum alloys such as 6101, 6061, 6063, 1350, 1370, 1060, and 1070 . Their hollow design significantly reduces weight compared to solid or flat busbars while maintaining high mechanical strength and rigidity. This makes them ideal for applications in substations, switchgear, industrial power distribution, and renewable energy systems .

Weight Advantages

The tubular structure maximizes the strength-to-weight ratio, allowing for easier handling, installation, and reduced structural support requirements . For example, a tubular busbar with a diameter of 120 mm and wall thickness of 10 mm provides a high cross-sectional area for current flow while being considerably lighter than a solid rod of the same diameter . The hollow design also improves heat dissipation, reducing temperature rise during operation and enhancing efficiency in high-current applications .

Material and Conductivity

• 6101 Alloy: High electrical conductivity (≥ 56% IACS), tensile strength 130–160 MPa, yield strength 60–120 MPa, suitable for high-current and mechanically demanding applications .
• 6061/6063 Alloys: Good conductivity (≥ 53% IACS), excellent corrosion resistance, and precise extrusion capabilities for complex shapes .
• 1350 Alloy: Exceptional conductivity (≥ 61% IACS), often used in transmission and transformation networks . These alloys balance lightweight design, mechanical durability, and electrical performance, making tubular busbars a preferred choice over traditional solid copper or flat aluminum busbars .
