A power line (1) for an electric vehicle (80), wherein a hollow elongated insulating enclosure (4) is fitted on top with a number of conducting plates (34) aligned in the travelling direction (8) of the vehicle and substantially coplanar with a horizontal road surface (ST). The enclosure (4) houses an elastically deformable strip conducting element (60) extending in the travelling direction and having a portion of ferromagnetic material (65). The strip conducting element (60) is attracted by the magnetic field generated (147) by the electric vehicle (80) travelling along the line, so as to deform and raise a portion (60a) of the strip conducting element (60) and connect at least one conducting plate (34) to a positive supply line (27) inside the enclosure. First and second elongated conducting elements (35, 35c) are provided on opposite sides of the conducting plates (34), and communicate with a ground potential to laterally define, in a direction crosswise to the travelling direction of the vehicle, a road surface safety region housing the conducting plates (34), and outside which the potential assumes a substantially zero voltage value, even in the presence of a layer of conducting fluid on the road surface (ST).
