상세한 설명

<br> Where a cable consists of polypropylene insulation adjacent to a copper conductor, a lead (Pb) layer may be positioned over the polypropylene insulation, which might improve its temperature score (e.g., low voltage armored power cable from about 96 degrees C. to about 125 degrees C.). Usually, as polypropylene insulation is stiffer than EPDM insulation, a fabric tape or braid may be foregone when the insulation is polypropylene insulation. For instance, the cushion layer 760 can embody one or more extra supplies equivalent to, for example, talc and/or polypropylene. FIG. Eight reveals an instance of a method 810 that features a formulation block 812 for formulating a cloth (e.g., a mixture of materials), an extrusion block 816 for extruding the formulated material, a formation block 820 for forming a cable that may be an armored cable and a utilization block 824 for using the formed cable. A pelletized material or pelletized supplies may be heated and deformed by way of extrusion (e.g., upon exposure to extrusion heat and stress). For instance, the cushion layer 760 can be formed by extrusion of material about the exterior surface of the metallic shield 750, which can be a lead (Pb) layer.<br> <br> In FIG. 7, the example cable seven hundred can include EPDM insulation because the insulation 730, which can have a wall thickness of roughly 1.6 mm (e.g., roughly 0.065 inch), can embody a lead (Pb) shield because the metallic shield 750, which can 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 might embody metallic armor (e.g., galvanized) because the armor layer 780, which might have a wall thickness of roughly 0.4 mm (e.g., approximately 0.015 inch). In FIG. 7, the conductor 710 generally is a stable copper conductor, the insulation 730 will 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 can 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. As defined, conductor and/or assembly geometries will be grouped where geometry of a number of cushion layers may be appropriately shaped to help preserve integrity of a number of metallic shields, which may perform as fuel barriers that may help to hinder permeation of gas (e.g., H2S, etc.) towards a conductor of a energy cable.<br> <br> FIG. 9 exhibits an instance of the cable seven-hundred during an armoring process where a strip of armor 780 is being utilized over an assembly that features three insulated and barrier layer protected conductors where every includes a cushion layer 760-1, 760-2 and 760-3. In the instance of FIG. 9, the cushion layers 760-1 and 760-three are surrounded to a higher extent by the armor 780 than the cushion layer 760-2, which is shown to be an intermediate component of the assembly while the cushion layers 760-1 and 760-three are proven to be finish or facet elements of the meeting that's being armored. In FIG. 7, the cushion layer 760 is exterior to the metallic shield 750 such that it will possibly mechanically cushion the metallic shield 750. For instance, the cushion layer 760 can mechanically cushion the metallic shield 750 from power that can be utilized by and/or carried out by the armor of the armor layer 780, which may be, for instance, a galvanized metallic armor. For instance, an extruded cushion layer can use a comfortable but tough polymeric material such that pressure utilized to a protective lead (Pb) layer will be absorbed because the cushion deforms, which can assist to reduce indentation depth and measurement as to the protecting lead (Pb) layer.<br> <br> Even small residual creases in a lead (Pb) layer from an armoring process have been shown to trigger premature failure resulting from results such as crevice corrosion. As explained, braid could be of a really low hoop energy as a consequence of the nature of the individual fibers and their orientations that make up the braid. Hydrocarbon wells tend to include some quantity of moisture and cable operating temperatures frequently exceed eighty levels C. Under such circumstances, the aforementioned braid materials can degrade and may even dissipate comparatively rapidly after installation in a hydrocarbon nicely. An ESP cable that included the aforementioned PET braided materials was topic to brine in a stress vessel for a period of days (e.g., 7 days in a stress vessel at 240 levels C.). Where a cable is to be a kilometer in length, a limiting fee of 6 meters per minute translates to roughly 167 minutes
