Abstract
Abstract A novel flat cable which has a number of parallel spaced conductors with tape segments having a conductive and insulative side woven between them at various positions along the length of the conductors. The weaving generally being done so that the conductive side touches alternate conductors. The whole complex may be encased in an outer insulation.
