Stranding line for Oman Cables industry

Pourtier, of Gauder Group, has installed a new con- centric stranding line, the COS 1200-2, for the production of a 37-wire concentric Cu/Al strand of 240mm². Mr Abdul Najeeb, pro- ject 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 to give 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.” OCI analysed the COS 1200–2 capabilities and was convinced that this would be the solution to cope with its production projections. Trials were conducted on a prototype, developed in 2006, which OCI personnel were invited to attend. Assembled in France in June 2008, OCI witnessed a successful ‘no load’ trial of the machine. The complete line was developed in October 2008 and final commissioning took place in January 2009.
