The capacitance of a laminated busbar or a busbar having layer-type construction is substantially increased by separating each conductor pair by means of a thin, flexible dielectric insulation layer which, in a cutout portion, comprises a thin disc-type ceramic capacitor which may be composed of a barium titanate composition which forms a thin substrate. The opposite sides of the substrate are metallised or coated with a thin metal layer. After introducing the insertion piece into the cutout portion, the insulation strip is partially cured, as a result of which some of the synthetic resin coating on the insulation flows into contact with the insertion piece and fixes it in the cutout portion of the insulation. As a result, the partly cured insulation can be manipulated during its introduction into a busbar assembly, in which it is placed between two strip conductors. The assembly is then laminated in a dielectric sheath in such a way that opposite sides of each dielectric ceramic insertion piece are in contact with the opposite surfaces of adjacent strip conductors. Each insulation layer, which separates adjacent strip conductors from one another in each case, may have any desired number of insertion pieces; for example, strip conductors which alternate in succession can be connected together by means of their projecting connections so that the capacitance between different strip conductors in a busbar can be selectively increased.
