Abstract
A cable includes at least one electrical conductor surrounded by a shield protecting against high-frequency electromagnetic interference. The shield includes an inner tape disposed lengthwise having a conductive layer and an outer tape disposed lengthwise having a conductive layer covered by an insulative layer. The conductive layer of the outer tape facing inwards so that the respective conductive layers of the inner and outer tapes are in contact. At least one of the two tapes has overlapping longitudinal edges. The insulative material of the insulative layer of the outer tape is adhesively bonded to the inside wall of a jacket. The protection is effective up to at least 500 MHz.
