Pourtier, of Gauder Group, is celebrating
the commissioning of a new concentric
stranding line, the COS 1200-2, for the
production of a 37-wire concentric Cu/
Al strand of 240mm² at 500rpm.
Mr Abdul Najeeb, project manager at
Oman Cables Industry (OCI), explains:
“This machine is the first in the world to
use the system of winding three wires
onto one coaxial bobbin (spinning on
the centre line of the machine), from
external coil baskets, and then stranding
from this single bobbin.
“This makes the machine very compact
and fast and with two bobbins per
module allows six wires to be run from
each individual module. OCI’s machine
has five modules and can have an
additional seven non-twisted wires fed
into the machine at the beginning of
the process, giving us thirty-seven wires
in total.
“In this new machine, Pourtier uses a
motorised control system to ensure the
uniform tension of each wire and can
thereby guarantee a more regulated
length in each bobbin.”
Mr Najeeb continues: “Other machine
manufacturers have used central
stranders which only wind one wire at
a time onto the bobbins. This allows
discrepancy between the lengths on
each bobbin and leads to more scrap
during the feeding-on process.”
Assembled in France in June 2008,
the machine had a no-load trial. The
complete line was developed in October
2008 and final commissioning took
place in January 2009.
