How easily a cable drum unwinds depends mainly on the technology used in the unwinding equipment. It is important for drums to unwind easily throughout the cable-laying process.
This is achieved by using rotating drum shafts with centering cones. These act as central bearings for the drum and allow it to unwind easily, whatever the weight.
This makes each cable-pulling procedure easier, which also results in lower pulling forces on the winch. In turn, this leads to lower compressive forces in the curves and increases the laying speed.
You’ll find all the equipment you need for this in the following sections.
