Product Construction:
Complete Conductor for bare grounding copper 120mm2:
Bare copper conductors are compressed concentric-lay-stranded, consisting of one or more layers of wires wrapped helically around a straight round central wire.Greater flexibility is afforded by using Class B stranding. The direction of lay for the outer layer is left hand lay. In 19 and 37 wire constructions, the direction of lay of each successive layer is reversed. Copper ground wires are manufactured using annealed copper wire and are manufactured in accordance with the requirements of the latest applicable issues of the ASTM specifications B3 and B8.
Features and Benefits:
Stranded bare soft or annealed hard copper conductors are suitable for direct burial and do not suffer from the inherent corrosion problems that an aluminum conductor would. Copper is easier than aluminum to terminate and join at splices and joints.
