A cable comprising: a plurality of conductor sets, each conductor set extending along a length of the cable and comprising: two or more insulated conductors, each insulated conductor comprising a central conductor surrounded by a dielectric material; first and second conductive shielding films disposed on opposite first and second sides of the conductor set, the first and second conductive shielding films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second shielding films in combination substantially surround the conductor set, and the pinched portions of the first and second shielding films in combination form pinched portions of the conductor set on each side of the conductor set; and an adhesive layer bonding the first shielding film to the second shielding film in the pinched portions of the conductor set, wherein the dielectric material comprises: 100 parts by weight of polyolefin; 18 to 40 parts by weight of a brominated flame retardant selected from the group consisting of decabromodiphenylethane, N,N'-ethylene-bis(tetrabromophthalimide), poly(pentabromobenzyl acrylate), and mixtures thereof; and 12 to 20 parts by weight of antimony trioxide. a plurality of conductor sets, each conductor set extending along a length of the cable and comprising: two or more insulated conductors, each insulated conductor comprising a central conductor surrounded by a dielectric material; first and second conductive shielding films disposed on opposite first and second sides of the conductor set, the first and second conductive shielding films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second shielding films in combination substantially surround the conductor set, and the pinched portions of the first and second shielding films in combination form pinched portions of the conductor set on each side of the conductor set; and an adhesive layer bonding the first shielding film to the second shielding film in the pinched portions of the conductor set, wherein the dielectric material comprises: 100 parts by weight of polyolefin; 18 to 40 parts by weight of a brominated flame retardant selected from the group consisting of decabromodiphenylethane, N,N'-ethylene-bis(tetrabromophthalimide), poly(pentabromobenzyl acrylate), and mixtures thereof; and 12 to 20 parts by weight of antimony trioxide. two or more insulated conductors, each insulated conductor comprising a central conductor surrounded by a dielectric material; first and second conductive shielding films disposed on opposite first and second sides of the conductor set, the first and second conductive shielding films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second shielding films in combination substantially surround the conductor set, and the pinched portions of the first and second shielding films in combination form pinched portions of the conductor set on each side of the conductor set; and an adhesive layer bonding the first shielding film to the second shielding film in the pinched portions of the conductor set, wherein the dielectric material comprises: 100 parts by weight of polyolefin; 18 to 40 parts by weight of a brominated flame retardant selected from the group consisting of decabromodiphenylethane, N,N'-ethylene-bis(tetrabromophthalimide), poly(pentabromobenzyl acrylate), and mixtures thereof; and 12 to 20 parts by weight of antimony trioxide. 100 parts by weight of polyolefin; 18 to 40 parts by weight of a brominated flame retardant selected from the group consisting of decabromodiphenylethane, N,N'-ethylene-bis(tetrabromophthalimide), poly(pentabromobenzyl acrylate), and mixtures thereof; and 12 to 20 parts by weight of antimony trioxide.
