ABSTRACT:
The capacitance of the laminated bar is substantially increased by separating each pair of conductors by a thin, flexible layer of dielectric insulation which has incorporated in an opening therein a thin, wafer-like dielectric ceramic insert, which may comprise a barium titanate composition forming a thin substrate opposite sides of which are metalized, or coated with a thin layer of metal. The strip of insulation is partially cured after the placement of the insert into its openings, thereby to cause part of the resin coating on the insulation to flow into engagement with, and to fix the insert in, the opening in the insulation. This permits the partially cured insulation to be manipulated during its incorporation into a bus bar assembly where it is interposed between two strip conductors. The assembly is thereafter laminated in a dielectric jacket in such manner that opposite sides of each dielectric ceramic insert will be engaged with the confronting surfaces of adjacent conductors. Any number of inserts may be employed in each layer of insulation which separates adjacent conductors; and alternate conductors, by way of example, can be connected to each other through the agency of their projecting terminals or tabs in order selectively to increase the capacitance between various conductors in a bar.
