For example, an extra cushion layer could also be utilized that surrounds assemblies the place the extra cushion layer is considerably circular in its cross-sectional shape (e.g., an annular wall about a group of assemblies). As mentioned, the shape of a cushion layer could also be considerably circular or of one other form similar to, for instance, considerably pie formed where it may surround a substantially pie shaped metallic barrier layer (e.g., a lead (Pb) barrier layer). As mentioned, an individual cushion layer might encompass an individual considered one of a metallic shield where such a cushion layer could also be considerably circular in form, substantially pie formed, or one other shape. As an example, a metallic shield layer could also be a sort of barrier layer that goals to provide protection against migration of fuel from an exterior area to an inside area. For instance, a lead (Pb) primarily based barrier layer can be a metallic shield layer that can also serve as a floor plane.

In FIG. 7, the conductor 710 can be a solid copper conductor, the insulation 730 might be an EPDM-based insulation, the metallic shield 750 could be a metallic lead (Pb) shield (e.g., a lead (Pb) layer), the cushion layer 760 will be an extruded polyethylene layer that has achieved a desired amount crosslinked (e.g., crosslinked polyethylene "XLPE") and the armor layer 780 can be a metallic armor. FIG. 7 reveals an example of a energy cable 700, an example of a energy cable 701, and an example of a power cable 702 where the facility cable 700, 701 and/or 702 may be appropriate for use in the system 300 of FIG. 3 or optionally in one or more different systems (e.g., SAGD, etc.). In some embodiments, a cable could use EPDM and/or nitrile primarily based elastomer compounds in a jacketing layer. Such a layer may be made with a desired thickness to provide for a cable rated for use particularly conditions (e.g., per cable specifications). For example, an quantity of carbon black will be an additive (e.g., about 0.01 to about 1 percent by weight). As an example, carbon black and/or one or more different supplies could help to protect towards UV and/or other radiation.

The a number of processors could execute such directions to implement (wholly or partly) one or more attributes (e.g., as a part of a method). As an example, the cushion layer 760 will be formed as a tube outlined no less than in part by a wall thickness and an interior cross-section dimension (e.g., an interior diameter) and/or an outer cross-part dimension (e.g., an outer diameter). For example, in some flat energy cable embodiments, two or more particular person coated conductors can be arranged in a side-by-side configuration (e.g., consider configurations similar to 2×1, 3×1, 4×1, and many others.) and, for instance, a number of armor layers will be applied over a jacket. In some embodiments, a barrier layer may be formed from one or more fluoropolymers, lead, or another materials resistant to downhole gases and fluids. In such an instance, the protecting layer can embody XLPE that has been extruded to kind a stable XLPE layer in regards to the lead (Pb) barrier layer. As an example, a cable may be a medium voltage power cable for an software the place lead sheathed cables can be utilized and where excessive temperature publicity or excessive cable reliability is desired. For instance, a cable and/or cable supplies might be examined by exposure to brine (e.g., from about 1 p.c to about 5 p.c salt in water), low voltage armored power cable which may approximate seawater or other kinds of saline environments.

A round energy cable may be used as energy cable in an electric submersible pumping system. A flat energy cable may be used as a power cable in an electric submersible pumping system. As an example, one or more polymeric materials could also be offered in a pelletized form that can be held in a bin of an extruder, which may be, for instance, a single or a number of screw extruder. In FIG. 7, the cushion layer 760 is exterior to the metallic shield 750 such that it can mechanically cushion the metallic shield 750. For example, the cushion layer 760 can mechanically cushion the metallic shield 750 from pressure that can be utilized by and/or performed by the armor of the armor layer 780, which could also be, for instance, a galvanized metallic armor. In FIG. 7, the example cable 700 can embrace EPDM insulation because the insulation 730, which might have a wall thickness of approximately 1.6 mm (e.g., roughly 0.065 inch), can embody a lead (Pb) shield as the metallic shield 750, which might have a wall thickness of roughly 0.6 mm (e.g., approximately 0.025 inch), can include crosslinked polyethylene as the cushion layer 760 and can include metallic armor (e.g., galvanized) because the armor layer 780, which may have a wall thickness of roughly 0.4 mm (e.g., approximately 0.015 inch).
