An X-ray cable has a plurality of elements arranged concentrically relative to one another and including from inside toward outside at least one inner conductor, an inner conducting sleeve, a high voltage isolation, an outer conducting sleeve, a screen and a casing. The inner conductor is composed of one or several wires with a thickness between 0.1 and 0.6 mm. At least one of the wires is composed of ferromagnetic material with high permeability at frequencies over 1 MHz, and a direct current resistance of the inner conductor lies under 20 OMEGA /m, so that without the use of damping members with a frequency above 1 MHz strongly increasing damping of occurring transient over voltages is provided.
