Compression type terminal lugs and ferrules with copper or aluminum for power cables conductors
1 Scope
This standard specifies the models, specifications, technical requirements, test, inspection rules, packaging, storage and transportation of compression type copper or aluminum or Cu-Al transition terminal lugs and copper or aluminum ferrules for power cables conductors of 35kV (Um=40.5kV) and below.
This standard is applicable to compression type copper or aluminum or Cu-Al transition terminal lugs and copper or aluminum ferrules for power cables conductors of 35kV (Um=40.5kV) and below. The applicable section range is (10~630)mm2 for copper conductor while (16~630)mm2 for aluminum conductor. It may also serve as reference for other wires and cables for fixed laying.
