Aluminium lugs should be used to terminate aluminium cables thus preventing a heat expansion miss-match leading to joint failure. It is important to use the correct dies, crimping tools and follow instructions as specified by the lug manufacturer to ensure good crimped joints. Non-circular (sector shaped aluminium conductors) require pre-rounding prior to introduction of the conductor into the cable lugs. Aluminium lugs feature barrels capped and filled with grease to prevent oxidation of the aluminium. Cablectrix supply aluminium lugs from Klauke to DIN standards and the Cembre AA-M range.
