Cuponal Busbars – Copper-Clad Aluminium Bars Made in the UK

Copper clad aluminium busbars that reduce weight and cost while maintaining reliable electrical performance.

Cuponal Busbar Manufacturers and Suppliers

ILF Products supplies and manufactures Cuponal busbars for electrical, power distribution and industrial applications from our Cannock, Staffordshire facility.

Cuponal combines a copper outer layer with an aluminium core. In practice, that gives designers an alternative to solid copper busbars wherever weight, cost and installation handling matter.

What is a Cuponal Busbar?

A Cuponal busbar is a copper clad aluminium busbar, often referred to as a CCA busbar.

Because it combines the surface properties of copper with the lower density of aluminium, it reduces overall weight while still supporting strong electrical performance. In other words, you keep a copper contact surface without the full weight of a solid copper bar.

Why Choose Cuponal Busbars?

Cuponal makes sense where the performance and material requirements of a project do not call for solid copper throughout. It suits larger power distribution systems and any application where reducing overall busbar weight makes manufacture, handling and installation more practical. Engineers keep a copper contact surface while lowering both mass and copper content.

2

Cost Control

Because the aluminium core lowers the copper content of each bar, Cuponal supports more cost-effective busbar production.

1

Lower Weight

Compared with solid copper, Cuponal can reduce busbar weight, so handling and installation become easier for fitters.

3

Reliable Performance

A copper outer surface supports effective electrical contact and current transfer at every connection point.

4

Custom Manufacture

Cuponal busbars can be punched, machined and finished to your project requirements, including tin plating where required.
