摘要： An electrical cable and method for making the same. The cable includes a plurality of conductors formed into a bundle and surrounded by an armor sheath. A barrier, formed of polyester or polypropylene tape, is disposed directly between the bundle of conductors and armor sheath. The tape is formed into layers, each layer extending over the length of the bundle of conductors. The tape has a thickness of about 1.5 to 2.0 mils. The preferred form of tape has longitudinally extending corrugations providing a corrugated thickness of 8.0 to 10.0 mils. Each layer of tape is applied either helically or longitudinally wrapping the tape around the bundle of conductors. The barrier separates the bundle of conductors and the armor sheath and provides impact resistance against the armor sheath being driven into contact with the conductors.
