A bundle of electrical cables ( 20 ) are shielded from electromagnetic interference by an elongate tape ( 1 ) wrapped widthwise round the bundle with its longitudinal edges ( 8,11 ) overlapping one another. The tape ( 1 ) includes a woven mesh ( 2 ) of bare-metal strands ( 5 ) sandwiched between outer and inner layers ( 4,3 ) of sheet-plastics, the weave being a narrow-fabric weave having warp strands ( 5 ) running longitudinally of the tape ( 1 ) and a single unbroken weft-strand ( 6 ). The mesh ( 2 ) is bare on the outside along one longitudinal margin ( 11 ) and also on the inside along the other longitudinal margin ( 8 ) for direct electrical contact between them within the overlap in establishing closed electrical circuits encircling the cable-bundle throughout the length of the tape ( 1 ). The margin ( 11 ) of the mesh ( 2 ) innermost in the wrap may instead be insulated, merely adding insignificant capacitance into the otherwise purely-resistive encircling circuits.
