One or more layers may be supplied, for example, to create an impermeable gasoline barrier. As an example, a metallic shield layer could also be utilized over an insulation shield layer. In some embodiments, an insulation shield layer may be considerably bonded to an insulation layer (e.g., through cross-linking, and many others.). For instance, a barrier layer generally is a layer exterior to a shield (e.g., an insulation shield layer) that may intention to offer extra safety from corrosive downhole gases and fluids. In the instance of FIG. 6, the cable 610 with the circular cross-sectional shape has an space of unity and the cable 630 with the oblong cross-sectional form has space of about 0.82. As to perimeter, where the cable 610 has a perimeter of unity, the cable 630 has a perimeter of about 1.05. Thus, the cable 630 has a smaller quantity and a bigger surface area when in comparison with the cable 610. A smaller volume can present for a smaller mass and, for instance, much less tensile stress on a cable that may be deployed a distance in a downhole setting (e.g., as a result of mass of the cable itself).

In the instance of FIG. 5, the MLE 500 (or "lead extension") a conductor 510, a conductor shield 520, insulation 530, an insulation shield 540 and/or a metallic shield 550, a number of different barrier layers 560, a braid layer 570 and armor 580. While the example of FIG. 5 mentions MLE or "lead extension", it may be implemented as a single conductor meeting cable for one or more of a variety of downhole makes use of. In some embodiments, a barrier layer could also be formed from a number of fluoropolymers, lead, or one other material resistant to downhole gases and fluids. In some embodiments, a jacket could also be constructed from one or more layers of a number of supplies (e.g., consider one or more of EPDM, nitrile rubber, HNBR, fluoropolymers, chloroprene, or another materials offering appropriate resistance to downhole situations). As to the cable jacket 470, it could also be round or as proven in the instance 401, rectangular (e.g., "flat"). FIG. 8 exhibits an example of a method 810 that features a formulation block 812 for formulating a fabric (e.g., a mixture of supplies), an extrusion block 816 for extruding the formulated materials, a formation block 820 for forming a cable that may be an armored cable and a utilization block 824 for utilizing the formed cable.

A thermoplastic extrusion can be performed at an virtually limitless velocity depending on the scale of the equipment used and the specs of the process. As an example, an antioxidant may be an additive. For instance, a cable may carry energy, at instances, for instance, with amperage of as much as about 200 A or extra. As explained, use of one or more cushion layers may help to cut back injury to a number of lead (Pb) barrier layers as to digging-in of one or more edges of armor. In some embodiments, low voltage armored power cable a cable might use EPDM and/or nitrile primarily based elastomer compounds in a jacketing layer. As to the cable armor 480 and 490, steel or metallic alloy may be employed, optionally in a number of layers for improved damage resistance. For example, a cable can include a number of conductors the place every conductor can carry present of a section of a multiphase power supply for a multiphase electric motor.

As an example, in a energy cable, a conductor, a lead (Pb) barrier layer and a cushion layer can form an assembly where energy cable is a multiple section energy cable that features a plurality of the assemblies wrapped by metallic armor. As to the cable 700, the cushion layer 760 will help to take care of integrity of the lead (Pb) barrier layer 750, for each of the assemblies. In such an instance, the protecting layer can include XLPE that has been extruded to kind a solid XLPE layer in regards to the lead (Pb) barrier layer. In such an example, the cushion layer can include polypropylene and/or clay. For example, a cable jacket may offer fluid-, gasoline-, and/or temperature-resistance to a cable. As to a braid or a braided layer, numerous sorts of supplies could also be used similar to, for instance, polyethylene terephthalate (PET) (e.g., utilized as a protective braid, tape, fabric wrap, and so on.).
