Pure copper conductor Bare copper conductor 70mm2 for earth connection purpose IEC/ASTM
Bare conductor is an uncoated copper wire used for transmitting electrical current.
They are either solid or concentric-lay-stranded, consisting of one or more layers of wire wrapped helically around a straight round central wire.
The direction of lay for the outer layer is left-hand lay. In multilayer constructions, the direction of lay for each successive layer is reversed.
These conductors can be used either for grounding use or for overhead use. Copper ground wires are manufactured using annealed soft copper wire and are manufactured in accordance with the requirements of ASTM specifications B3 and B8, IEC60228, EN 13602.
