Abstract
An electrical cable includes a core, a jacket and improved shielding with unexpectably low transfer impedance. The shielding includes an inner foil laminate, a braided sleeve, and an outer foil laminate, each foil laminate having at least one conductive layer and at least one strength-giving non-conductive layer. At least one of the foils includes a shorting fold to limit the slot effect. Preferably, the inner foil has two conductive layers, and the outer foil has the shorting fold.
