Pre-insulated bimetal lugs for LV service lines
Pre-insulated bimetal lugs CPTAU are used at the ends of aluminum conductors made according to Standards DIN 48201/1
and DIN EN 50182. They are made of two different metals, aluminum and copper, and as such achieve permanent conductive
joint between these metals. The Lugs are marked in order to ensure correct crimping. The picture shows correct crimping.
The achieved joint is not meant for mechanical tightening. The Lugs have oil barrier.
The aluminum part that is crimped is made in accordance with Standard DIN 46329.
Applications:
CPTAU Pre-insulated Bi-metal lugs are designed to connect ABC cables to transformers, switchgear etc on the pole top.
They are Pre-insulated, there is no requirement for insulation, heat shrink at the pole top.
Materials:
99.9% purity copper & 99.5% purity aluminium
Technical of production: friction welding.
Technical specification:
• EN 50483-4
• NF C 33-021
