£4.08
The Wöhner 01258 is a premium plain insulated flexible copper busbar designed for very high-current industrial power distribution. Manufactured using 10 laminated copper strips measuring 40 × 1 mm, it provides an impressive IEC rated current of 1,053 A and is supplied in a practical 2 metre length. Its laminated construction offers exceptional flexibility while maintaining excellent electrical conductivity for demanding low-voltage applications.
Unlike conventional solid copper busbars, the laminated design eliminates the need for specialist bending equipment, significantly reducing installation time and simplifying panel assembly. The integrated 2 mm thick halogen-free insulation removes the requirement for additional protective covers, creating safer, cleaner and more compact switchboard installations.
Designed for OEM panel builders, switchgear manufacturers and industrial electrical contractors, the Wöhner 01258 delivers reliable long-term performance in demanding power distribution systems where flexibility, safety and high current capacity are essential.
The Wöhner 01258 is designed for demanding high-current applications where rigid copper busbars would be difficult to install. Its laminated construction allows simple routing through confined switchboard layouts while maintaining excellent electrical performance and significantly reducing installation effort.
Its integral insulation enhances operator safety while simplifying panel construction by eliminating the need for separate protective covers, resulting in compact, efficient and professional electrical assemblies suitable for modern industrial installations.
