Some important comments on contact crimping

Our aluminium terminals are designed

according to the same criteria and
requirements as mentioned above, and
should be crimped with a punch tool that
ensures that the aluminium insulating
oxide layer is broken and that good
points of contact are created between
conductors and terminal.

Cables

to be used in conjunction with cables
