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 using die-sets 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.

 

Cembre Aluminium Cable Lugs - Specification Notes

Cembre AA-M series cable lug terminals are made from aluminium of a purity equal to or greater than 99,5%. Cembe cable lugs are designed to accept a variety of conductor forms, especially BS6360 low stranded compacted conductors. Non-circular aluminium cable conductors, such as solid sector aluminimum conductors, may require pre-rounding prior to introduction to the terminal lug. Cembre pre-rounding compression die sets are available.

Cable lug barrels are capped and filled with grease so as to avoid oxidation of the aluminium and create a water-blocked connection. Suitable for high voltage cable termination up to 33kV. The absence of the inspection hole prevents moisture ingress, making these Cembre aluminium cable terminals also suitable for outdoor applications. Die crimping positions are marked along the lug barrel length to ensure safe and reliable cable crimping of the connector. 

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.
