    Abstract: A wireline cable includes an electrically conductive cable core for transmitting electrical power. The wireline cable further includes an inner layer of a plurality of first armor wires surrounding the cable core and an outer layer of a plurality of second armor wires surrounding the inner layer, wherein a diameter of the outer layer of the plurality of second armor wires is smaller than a diameter of the inner layer of the plurality of first armor wires.

    Abstract: Cables that include a conductor and an optical fiber. In some embodiments, the cable can include an optical fiber loosely disposed within an enclosure. A conductor layer can be disposed about the enclosure. An insulation layer can be disposed about the at least one conductor layer. An inner layer of armor strength members can be helically disposed about the insulation layer. An outer layer of armor strength members can be helically disposed about the inner layer of armor strength members. The armor strength members in the outer layer of armor strength members can be at an opposite helix compared to the armor strength members in the inner layer of armor strength members. An outer jacket can be disposed about the outer layer. In other embodiments, the cable can include an optical fiber in a coupled electro-optical package, where the conductor layer can be disposed about the electro-optical package.

    Abstract: In some embodiments, a cable can include an electrically conductive inner core. A first insulation layer can be disposed about the inner core. An electrically conductive layer can be disposed about the first insulation layer. A second insulation layer can be disposed about the electrically conductive layer. A first polymer jacket can be disposed about the second insulation layer. The first polymer jacket can include a first layer of armor strength members disposed therein. A second polymer jacket can be disposed about the first polymer jacket. The second polymer jacket can include a second layer of armor strength members disposed therein. An outer polymer jacket can be disposed about the second polymer jacket. At least one of the first polymer jacket, the second polymer jacket, and the outer polymer jacket can be formed from an aliphatic polyketone polymer, an ethylene-propylene copolymer, a polyolefin elastomer, a polypropylene, or a cross-linkable polyethylene.
