Bare Copper Ground Wire Conductor
Product Construction:
Complete Conductor:
Bare copper conductors are compressed
concentric-lay-stranded consisting of one
or more layers of wire wrapped helically
around a straight round central wire. Each
successive layer has six wires more than the
layer immediately beneath. 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 copper conductors
are suitable for direct burial and do not suffer
from the inherent corrosion problems that an
aluminum conductor would. Copper is almost
twice as conductive as aluminum. Copper is
easier than aluminum to terminate and join at
splices and joints.
Applications:
Stranded bare soft or annealed copper
conductors are recommended for use as
neutrals, in circuit ground connections as
well as machinery and equipment grounding
systems. Soft copper may not be used for
overhead conductor transmission or distribution
applications. Soft copper may be used for
transformer drop leads or other non-tension
hook-up jumpers.
Options:
• Center strand ID marking
Packaging:
The conductor is shipped on wooden reels with a
shipping length tolerance of +/- 5%.
