Wöhner 01257 plain insulated flexible laminated copper busbar, 8 × 40 × 1 mm with a 320 mm² copper cross-section and 2 metre length for high-current industrial power distribution.
£4.08
The Wöhner 01257 is a heavy-duty plain insulated flexible copper busbar designed for demanding high-current power distribution applications. Manufactured from 8 laminated copper strips measuring 40 × 1 mm, it delivers a rated current of approximately 1,020 A and is supplied in a convenient 2 metre length, making it ideal for industrial switchboards, OEM machinery and low-voltage power distribution systems.
Its laminated copper construction provides excellent flexibility compared with conventional solid copper busbars, eliminating the need for specialist bending equipment and significantly reducing installation time. The integrated 2 mm thick halogen-free insulation removes the need for additional protective covers, resulting in safer, cleaner and more compact electrical assemblies.
Designed for panel builders, switchgear manufacturers and electrical contractors, the Wöhner 01257 combines outstanding conductivity, mechanical strength and long-term reliability for high-current flexible power connections in demanding industrial environments.
The Wöhner 01257 offers a practical alternative to rigid copper busbars by combining excellent current-carrying capability with outstanding flexibility. The laminated construction allows easy routing through confined switchboard layouts while reducing assembly time and mechanical stress on electrical equipment.
Its integrated insulation improves operator safety and simplifies switchboard construction by removing the need for separate protective covers, making it ideal for modern low-voltage power distribution systems.
