How to crimp a cable

When copper comes into contact with oxygen, it oxidises to form copper oxide. Copper oxide is green in colour and acts as an insulator. It stops the current from travelling and is a disaster for the charge.

A tin cover around the copper protects it from oxygen and keeps it fresh for longer. That’s why we offer a wide range of tinned products.

To protect the cable, crimping is critical. Crimping tool, lug and cable must fit together. With hexagonal crimping, it is possible to crimp so that the oxygen does not enter and oxidise the cable.
