Flexible Busbars Manufactured in the UK
Flexible busbars manufactured to your drawings for compact, reliable and efficient electrical connections.
Flexible Busbar Manufacturers and Suppliers
ILF Products manufactures and supplies flexible busbars in the UK for electrical, power distribution and industrial customers.
Each flexible busbar is made to support reliable current transfer where movement, vibration, limited space or installation flexibility must be considered. In turn, they suit connections that a rigid bar would struggle to make.
What is a Flexible Busbar?
A flexible busbar is built from multiple thin layers of copper or aluminium. The mounting areas remain firm for a secure connection, while the centre section stays flexible.
Because of this construction, flexible busbars are useful where rigid busbars or large cable sets are harder to install, for example in compact panels.

Why Choose Flexible Busbars?
Flexible busbars connect fixed electrical components where a rigid link would place unnecessary stress on terminals or connection points. Their construction accommodates minor alignment differences, thermal expansion and operational movement. The result is a more adaptable connection within the assembly, and less strain on the equipment either side.

Easier Installation
Because they can be shaped, bent and positioned more easily than rigid busbars or bulky cables, installation takes less effort.
1
Space Saving
A single flexible busbar can replace multiple cable runs, so contractors need less space for bending and routing inside the enclosure.
3
Reliable Connections
Firm mounting areas give secure connection points, so power transfers effectively across the joint.
4
Custom Manufacture
Each flexible busbar can be manufactured to your drawings to suit your layouts, panels and performance requirements, including punched or drilled connection areas.
