Al aluminum tubular ring terminals according to DIN 46329 (tube part), for crimping. They are used where it is necessary to connect the cable to, for example, a switchgear, busbar or other device using a screw terminal. Recommended for use in damp rooms and with high and long-term current loads.
The effectiveness of crimping (fixing the terminal on the cable) depends on the use of an appropriate tool and a die adapted to the cross-section.
