It is a connector made for single-strand or multi-strand Al wire . ALD connector is made according to DIN 46267 part. 2. It is designed for single-strand conductor with the cross-section from 25 mm2 to 300 mm2, and a multi-strand round and sector conductor from 16 mm2 to 625 mm2.
ALC cable connector has thin walls and therefore it is called a thin-walled connector. It can be crimped on single-strand and multi-strand wires with the cross-section from 16 mm2 to 240 mm2.
ALS cable connector belongs to the category of reducing and tight connectors. It allows to reduce the multi-strand conductor cross-section, for example from 35 mm2 to 25 mm2, from 50 mm2 to 25 mm2 or from 600 mm2 to 300 mm2. The crimping tools recommended by the manufacturer are for example: EPZC300, EPZ300, GZ300, HRZ300, PRZ240, GU625.
ALR reducing connector can be also used for crimping on single-strand wire. It is designed for the conductor cross-section from 25 mm2 to 625 mm2. The crimping tools are as follows: EPZC300, EPZ300, GZ300, HRZ300, PRZ240, GO300, GU300, HR300, GU625.
