Helping to meet the increase in demand

The new rigid standing lines type “RFS 630-TZ” and “RFS 800-TZ” have been designed by Pourtier to cope with the increasing demand for overhead conductors using trapezoidal wires. This new generation of conductors is used more and more to increase the transmission capacity of existing lines, thus avoiding costly and time consuming projects for completely new lines. These conductors are using central core made of steel (ACSS/TW and ACSR/TW) or made of composite material (ACCC™). ACCC™ is the last innovative overhead conductor made of composite centre and soft aluminiumwire with trapezoidal shape. In order to handle properly this particular product, Pourtier rigid stranders gather several special features: a fine tension control, a straight and smooth passage for the trapezoidal wires all along the line to avoid any deformation of wires, the exclusive use of rollers – instead of eyelets – to avoid friction on the wires and large sized cage bearings for straight passage of wires.
