Cembre Aluminium Lugs

Aluminium Cable Lugs - Cembre

Cembre AA aluminium lugs are suitable for low voltage crimping and terminating BS6360 aluminium conductors including low stranded compacted conductors - 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. Cembre AA aluminium lugs are also suitable for 11kV and 33kV cable termination up to 300sqmm.

Compression Connectors for Connecting & Terminating Conductors
Compression (crimp) lugs are an established method of connecting and terminating aluminium cable conductors. To ensure a reliable crimp connection or termination, the following should be observed.

*Both cable conductor and compression crimp lug should be cleaned down using cable cleaning wipes
*The size, shape and metal (copper or aluminium) must be correct for the cable conductor
*The correct crimp die set should be selected
*The cable conductor must be fully inserted into the crimp lug
*The correct compression or crimping sequence must be followed and the full compression pressure applied.

Failure to observe these precautions can result in a compression connector, lug or termination that fails in service.

NOTE - Copper terminal lugs cannot be used to terminate an aluminium conductor. Aluminium conductors will thermally expand greater than copper conductors for a given temperature, therefore, under load, the copper will act to constrict the aluminium, causing permanent extrusion of the aluminium from the joint which will ultimately lead to a loose connection and potential failure of the joint.
