A capacitive cable comprised six long, thin and narrow electrode plates or strips 101, 102, 103, 104, 105, 106. Typically they are 5 km long, 10 cm wide and 0.5 mm thick of aluminium or copper foil. Individual ones of them are separated by 0.25 mm thick polypropylene ribbons 107 insulating the individual strips from each other in an insulating manner. The assembly of strips and ribbons is contained within an insulating sheath 108.

At opposite ends 111,112, the alternate strips are cut off short and the remaining fingers 114,115 are joined together and to connection wires 116,117, typically by riveting 118. The wires are insulated and the insulating sheath extends onto the insulation of the wires, whereby the entire cable is insulated for safe contact with foreign objects between the ends.

The present invention relates to a multi-layered aluminum oxide capacitor comprising an aluminum substrate; a plurality of aluminum oxide layer formed in at least a portion of on both sides or one side of the substrate with respect to the aluminum substrate; and a plurality of electrode layers formed on the aluminum oxide layers. According to the present invention, manufacturing process is more simplified since Al.sub.2O.sub.3 insulation layer is formed by anodizing the aluminum layer without forming an extra insulation layer after forming the aluminum layer, so that the manufacturing cost can be reduced, and also a multi-layered capacitor having a high capacitance and a high reliability can be provided by stacking capacitors comprising a plurality of aluminum oxide layers using a more simplified process according to the present invention.
