The method involves unwinding the power line (4) at the installation height and at the desired tension from a storage drum (16) on a machine (1). The application of pressure on the tensioned power line by a pressure element is reduced during a transition phase from when the machine is at rest to a working movement of the machine. The tension is reduced during a transition from working motion to rest. Independent claims are also included for the following: a machine for installing a power line.
