DTL Cu-Al lugs use friction welding to bond aluminum and copper at the molecular level, eliminating galvanic corrosion, with precise crimping and IEC 61238 compliance.
WANGYUAN DTL Cu-Al commecting lugs are designed for power cable termination in distribution and overhead power systems. Adopting advanced friction welding technology, it achieves molecular-level bonding between the high-purity aluminum and copper , fundamentally eliminating electrochemical corrosion caused by dissimilar metal connection. The precision-machined aluminum barrel ensures tight and reliable crimping, and the tin-plated copper end delivers excellent conductivity. Covering cable cross-sections from 10mm² to 240mm² with complete specifications, all products comply with IEC 61238 and relevant international power standards, maintaining stable electrical performance in harsh environments.
