Cuponal Busbars
Copper clad aluminium busbars designed to reduce weight and cost while maintaining reliable electrical performance.
Cuponal Busbar Manufacturers and Suppliers
ILF Ltd supplies and manufactures Cuponal busbars for electrical, power distribution and industrial applications.
Cuponal combines a copper outer layer with an aluminium core, giving customers a practical alternative to solid copper busbars where weight, cost and installation handling matter.
What is a Cuponal Busbar?
A Cuponal busbar is a copper clad aluminium busbar, also known as a CCA busbar.
It offers the surface properties of copper with the lower density of aluminium, helping reduce overall weight while supporting strong electrical performance.
