Fusible screw terminalsandmechanical couplings are the ideal choice for connecting aluminium or copperlow and medium voltage conductors indoors, outdoors and underground. The fuse screws are made of aluminium and are designed to be screwed in a way that leaves no protruding threads. The cable lugs and fuse screw couplings have centring lugs to ensure the correct alignment of the various conductor sections within the terminal collar.
