Minimise conductor flashover - reduction in conductor spacing
Capped and filled with jointing compound
Crimp with standard hexagonal dies - from palm outwards
Specially designed for CCT overhead conductors
Aluminium CCT Lug
Designed for CCT (Covered Conductor Thick) Conductors, the CABAC range of Aluminium lugs are heavy-duty with thicker than normal barrels and are able to withstand fault current situations.
As with all CABAC Aluminium lugs this range is made by a forging process from solid 99.6% pure electrical grade Aluminium rod which eliminates any imperfections in the metal structure which are often found in cast Aluminium lugs. This improves the long term electrical reliability, elimination future hot joints. The lugs are tin plated to reduce corrosion, and improve crimping contact resistance. They are filled with jointing compound and capped.
Before crimping, the conductors should be scratch brushed and the lug should be crimped using standard hexagonal dies, crimping from the palm outwards to force jointing compound into the conductors.
CCT Conductor Defined
CCT Conductor is an Aluminium stranded overhead conductor, with a grey bonded polyethylene covering. It is filled with a water blocking compound to restrict passage of water along the conductor between the strands if the outer covering is damaged. The water blocking minimises corrosion and maximises service life. The main advantage of CCT conductor is that it minimises flashover of conductors, and allows a reduction in the conductor spacing. This decreases the vegetation clearance space, and enhances the visual aspect of the line. Flashovers caused by wildlife, in particular possums, are reduced to a minimum. CCT is becoming a standard conductor system with many authorities.
CCT conductors have differing cross sections from normal conductors with nominal cross sections of 40, 80 and 180mm2.
