Such cushioning might help to preserve the integrity of the metallic shield 750 through one or more mechanisms. In such an example, an extruded cushion layer can obtain a desired hoop stress, low voltage armored power cable which may help the extruded cushion layer to retain its form. As an example, an additional cushion layer may be utilized that surrounds assemblies the place the additional cushion layer is considerably circular in its cross-sectional form (e.g., an annular wall about a group of assemblies). For instance, the cushion layer 760 might be formed as a tube defined no less than in part by a wall thickness and an interior cross-section dimension (e.g., an inner diameter) and/or an outer cross-part dimension (e.g., an outer diameter). As mentioned, a cable can include lead (Pb), which may be within the form of a lead (Pb) layer (e.g., a barrier layer). For example, a pump system can include a pump; a submersible electric motor operatively coupled to the pump; and a energy cable for supply of electrical energy to the submersible electric motor, the place the power cable includes a conductor, a lead (Pb) barrier layer disposed concerning the conductor, a cushion layer disposed concerning the lead (Pb) barrier layer where the cushion layer consists of crosslinked polyethylene (XLPE), and metallic armor wrapped concerning the cushion layer.

In the geometry of the facility cable 702, three assemblies are proven where every meeting includes a conductor 710 (e.g., a considerably pie formed conductor with an arc span of approximately one hundred twenty levels), insulation 730 (e.g., a considerably pie shaped layer of insulation that surrounds the conductor 710), a metallic shield 750 (e.g., a substantially pie formed layer of lead (Pb) that surrounds the insulation 730, and a cushion layer 760 (e.g., a considerably pie shaped layer of fabric that surrounds the metallic shield 750. As shown, the three assemblies might be grouped (e.g., A hundred and twenty levels every to type a circular cross-part of 360 degrees) and one or more additional layers may be utilized that surrounds the three assemblies where a number of of such layers can include armor. In some embodiments, an insulation shield layer may be applied by way of extrusion. In some embodiments, a barrier layer could also be formed from a number of fluoropolymers, lead, or another materials resistant to downhole gases and fluids.

In some embodiments, a jacket could also be constructed from a number of layers of one or more materials (e.g., consider one or more of EPDM, nitrile rubber, HNBR, fluoropolymers, chloroprene, or another materials providing suitable resistance to downhole circumstances). In some embodiments, a metallic shield layer could serve to electrically isolate the phases of the cable from one another. As an example, the metallic shield 750 can have a wall thickness that's lower than approximately 1 mm. For example, the cushion layer 760 can embrace one or more further supplies resembling, for instance, talc and/or polypropylene. As an example, a way can include crosslinking at least a portion of polyethylene after armoring and/or crosslinking not less than a portion of the polyethylene earlier than armoring. In such an example, the cushion layer can include clay and/or polypropylene. Talc or talcum is a clay mineral composed of hydrated magnesium silicate, for example, consider a number of of the chemical system H2Mg3(SiO3)four or Mg3Si4O10(OH)2.

Based on the DMA outcomes, a blend XLPE with PP with at the very least approximately 25 wt % might considerably enhance the thermal stability and chemical compatibility of uncured XLPE. As mentioned, an individual cushion layer might encompass an individual one in all a metallic shield the place such a cushion layer may be considerably circular in shape, substantially pie formed, or another shape. As one example, the cushion layer 760 might be formed of a cloth with a shape and measurement that helps to keep up the form and measurement of the metallic shield 750. In such an example, the shapes could also be considerably circular. As mentioned, a cushion layer could also be of a non-circular form equivalent to considerably pie shape. As an example, a substantially circular formed cushion layer could also be extruded a few plurality of considerably pie formed cushion layers that are grouped. In FIG. 7, the ability cable seven hundred consists of three conductor assemblies the place every assembly includes a conductor 710, insulation 730, a metallic shield 750, a cushion layer 760 and an armor layer 780. In FIG. 7, the ability cable seven hundred is configured with a flat geometry; whereas, the facility cables 701 and 702 are configured with a spherical geometry the place conductors are considerably pie formed in their cross-part.
