Aluminium through connectors

Aluminium through connectors and compression joints should be used to join aluminium cables thus preventing a heat expansion miss-match leading to joint failure if copper joints are used. It is important to use the correct dies, crimping tools and follow instructions as specified by the connector manufacturer to ensure reliable crimped joints. Non-circular (sector shaped aluminium conductors) require pre-rounding prior to introduction to the connectors.
