Electrical conductor copper pipe for cable lugs is made of pure copper (copper content: more than 99.95%) and with high electrical conductivity (more than 100% IACS). The electrolytic copper tube is in UNS C11000 alloy conforms to ASTM B188 standard, or Cu-ETP conforms to EN 13600 standard.
The dimension of the tubes is designed to obtain the most efficient electrical conductivity and mechanical strength to resist vibration and pull out. Our electrical conductor copper pipe is available in nominal size from 1/4” to 4” (outer diameter from 13.7mm to 114mm)
