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 traveling 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 traveling 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 ) traveling along the line, so as to deform and raise a portion (60a) of the strip conducting element (60) and connect 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 traveling 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). |
