Abiko AKK 630 — aluminium-copper (AlCu) bimetallic compression cable lug for terminating a 630 mm² aluminium conductor onto a bolted connection. The aluminium barrel is friction-welded to a copper palm from solid material, so an aluminium conductor connects directly to a copper busbar or apparatus terminal without a separate bimetal washer. The copper palm is supplied undrilled (UB) and is drilled on site to the required hole. Two compression crimps are made on the aluminium barrel; accepts solid (IEC 60228 Class 1) and stranded (Class 2) aluminium conductors.
