How to crimp a cable

When copper comes into contact with oxygen, the copper oxidizes and forms copper oxide. The copper oxide is green in color and acts as an insulator. It prevents the current from getting through and is a catastrophe for charging.

A tin coating around the copper protects against oxygen and allows the copper to stay fresh longer. That is why we offer a wide range of tinned products.

To protect the cable and ensure a reliable connection, crimping is critical. The cable, tubular cable lug, and crimping tool must be matched to each other. To comply with applicable standards, components that are not intended to be used together must not be combined, as this can lead to inferior crimps with high transition resistance and reduced mechanical strength.

With a correctly performed hexagonal crimp, a gas-tight connection is achieved, which prevents oxygen from penetrating and oxidizing the conductors. This is crucial for both long service life and electrical safety.
