Bi-Metal Switchgear Connector
For stranded sector and circular stranded aluminium conductor.
The CABAC Bi-Metal Switchgear Connector range is designed for terminating aluminium conductors onto a 12mm copper switchgear stem.
The connector consists of a bi-metal lug and a steel clamping collar. The lug is friction welded from the highest quality aluminium (99.6 pure) and copper (99.9% IACS). The aluminium barrel is coated with jointing compound and sealed with a plastic cap. A slot is machined in the copper end of the bi-metal lug into which the 12mm switchgear stem is inserted. A clamping collar incorporating an allen head grub screw applies pressure between the switchgear stem and bi-metal lug to achieve current transfer through this bolted connection. The clamping collar is made from a zinc-plated steel ring and a cut in the ring prevents heat generating eddy currents from flowing in the steel ring.
These connectors are made to Australian dimensions and can be crimped with standard Australian tooling.
