French tubular busbar models

French tubular busbars are primarily available in aluminum and copper, designed for high-current applications with customizable dimensions and surface treatments.

Overview of Tubular Busbars in France

French tubular busbars are widely used in power distribution, industrial energy systems, and renewable energy installations. They are typically hollow, extruded profiles that allow efficient heat dissipation and high current-carrying capacity. The hollow structure reduces weight while maintaining mechanical strength, making them ideal for high-current applications .

Materials and Specifications

• Aluminum Tubular Busbars: Commonly made from alloy 6101, offering a balance of high electrical conductivity (≥56% IACS) and mechanical strength. Typical tensile strength ranges from 130 to 160 MPa, with yield strength between 60 and 120 MPa. Aluminum busbars are lightweight, corrosion-resistant, and can be customized in lengths up to 8 meters, with options for drilling, cutting, welding, and surface treatments .
• Copper Tubular Busbars: Used for applications requiring maximum conductivity. Copper busbars can be bare or coated with tin, nickel, or silver to enhance corrosion resistance and surface contact quality .

Applications

• Substations and Power Distribution: Tubular busbars efficiently handle high currents while minimizing energy losses and heat buildup .
• Industrial Equipment: Used in machinery and control panels where compact, high-current connections are required.
• Renewable Energy Systems: Suitable for solar, wind, and hybrid energy systems due to their lightweight and corrosion-resistant properties .
• Electric Vehicles and Hydrogen Systems: Rigid or flexible busbars are used for interconnections in EVs and hybrid vehicles, often with overmolded insulation for safety .

Customization and Manufacturing

French manufacturers offer customizable busbar solutions, including:

• Length, diameter, and wall thickness adjustments
• Surface treatments such as anodizing or plating
• Pre-drilled holes, cutouts, and welded ends for easy installation
• Laminated or multilayer designs for compact power electronics applications Companies like HTS-Alu specialize in aluminum tubular busbars, while Flobex France and Scherdel FR provide both copper and aluminum solutions for industrial and automotive applications .

Advantages

• High current-carrying capacity
• Efficient heat dissipation due to hollow structure
• Lightweight and corrosion-resistant
• Flexible installation options
• Customizable to project-specific requirements French tubular busbars combine mechanical durability, electrical efficiency, and design flexibility, making them suitable for a wide range of industrial and energy applications.
