Electrical cable with shielding film with gradual reduced transition area

A shielded electrical cable, comprising:

• a plurality of conductor sets extending along a length of the cable and being spaced apart from each other along a width of the cable, each conductor set including one or more insulated conductors;
• first and second shielding films including concentric portions, pinched portions, and transition portions arranged such that, in transverse cross section, the concentric portions are substantially concentric with one or more end conductors of each conductor set, the pinched portions of the first and second shielding films in combination form pinched portions of the cable on two sides of the conductor set, and the transition portions provide gradual transitions between the concentric portions and the pinched portions;
• wherein
• each shielding film comprises a conductive layer;
• a first one of the transition portions is proximate a first one of the one or more end conductors and has a cross-sectional area A1 defined as an area between the conductive layers of the first and second shielding films, the concentric portions, and a first one of the pinched portions proximate the first end conductor, wherein A1 is less than a cross-sectional area of the first end conductor;
• and
• each shielding film is characterizable in transverse cross section by a radius of curvature that changes across the width of the cable, the radius of curvature for each of the shielding films being at least 100 micrometers across the width of the cable.
