The figure shows an electrical cable with conductors (1) of metal, surrounded by each of an inner conducting layer (2), insulation (3) and an outer conducting layer (4). A moisture barrier (11) with an electrically conducting layer surrounds the conductors. Shield strips (5) of at least partially conducting material are located in the regions between the outer conducting layer (4) and the moisture barrier (11). Electrically conducting shield wires (6) run along the shield strips and are placed through these into electrical contact with the electrically conducting layer of the moisture barrier (11). The shield strips support the moisture barrier from the inside, such that the moisture barrier can in a simple manner be made watertight when it is applied. The shield strips (5), the moisture barrier (11) and the shield wires (6) together constitute an efficient electrical shield for the cable. Penetration of an electrically conducting object into the cable results in a fault current that can be easily indicated, such that an applied cable voltage can be removed.
