摘要：Embodiments of the invention include an electrical cable apparatus and methodfor making. The electrical cable apparatus includes a plurality of paired conductiveelements, a dielectric jacket formed around the plurality of paired conductive elements,

and at least one dielectric film separating the pairs of conductive elements within thedielectric jacket. For example, for an arrangement having four twisted pair of copperwires within an electrically insulating jacket, two dielectric films surround alternating pairsof individually insulated conductor elements. The dielectric film is made of one or moreof the following materials: ethylchlorotrifluoroethylene (ECTFE or HALAR®), poly(vinylchloride) (PVC), polyolefins, and fluoropolymers including fluorinated ethylene-propylene (FEP or TEFLON®), perfluoroalkoxy polymers of tetrafluoroethylene andeither perfluoropropyl ether (PFA) or perfluoromethylvinyl ether (MFA). Alternatively,the dielectric film is made of woven glass yarn tape such as KAPTON®. The dielectric filmhas a width, e.g., of approximately 0.125 to 0.250 inch and a thickness, e.g., ofapproximately 2 to 20 mils (0.002 to 0.020 inch). Alternatively, a dielectric film ispositioned between individual conductive elements within the conductor pairs. Themethod for making an electrical cable includes providing a plurality of the pairedconductive elements, forming the dielectric film around one or more of the conductorpairs and/or forming the dielectric film between the individual conductors within one ormore conductor pairs, and forming the dielectric jacket around the conductor pairs. Thethin dielectric film provides separation between conductor pairs and/or betweenindividual conductors within conductor pairs to reduce crosstalk therebetween.
