For example, a layer 762 may be an extra cushion layer 762 that surrounds the three cushion layers 760 of the grouped assemblies, which might further assist to protect the metallic shields 750 from an armoring course of. In FIG. 7, the conductor 710 could be a strong copper conductor, the insulation 730 may be an EPDM-primarily based insulation, the metallic shield 750 generally is a metallic lead (Pb) shield (e.g., a lead (Pb) layer), the cushion layer 760 could be an extruded polyethylene layer that has achieved a desired quantity crosslinked (e.g., crosslinked polyethylene "XLPE") and the armor layer 780 generally is a metallic armor. For instance, the cushion layer 760 can be formed as a tube outlined not less than partly by a wall thickness and an inner cross-part dimension (e.g., an inner diameter) and/or an outer cross-part dimension (e.g., an outer diameter). As an example, a cushion layer could be characterized not less than partially by hoop strength. In such an example, an elective armor layer may be of a thickness of about 0.5 mm.
In such an instance, the protective layer generally is a cushion layer that may be an extruded cushion layer that includes XLPE and optionally one or more additional supplies (e.g., PP, talc, carbon black, and so on.). In such an example, the metallic shield layer could serve as a floor aircraft. In some embodiments, an insulation layer and insulation shield layer could be co-extruded via strain extrusion and cured utilizing compatible cure systems with considerably similar cure charges. In some embodiments, a mixture of extruded and taped layers could also be used to kind the barrier layer. In other embodiments, an insulation shield layer may be tandem extruded with an insulation layer. In some embodiments, an insulation shield could also be strippable (e.g., to permit for termination and electrical testing of the cable). As an example, insulation and shield could also be strippable as a unit, for instance, the place considerably cross-linked at an interface between the insulation and the shield. As an example, a metallic shield layer could also be formed from quite a few metallic materials together with, but not restricted to: copper, aluminum, lead, and alloys thereof. Additionally, low price fillers or additives may be compounded right into a cushion layer material to additional scale back material price.
As talked about, a person cushion layer might encompass a person one in every of a metallic shield where such a cushion layer could also be substantially circular in form, considerably pie formed, or one other shape. For example, a lead (Pb) primarily based barrier layer could be a metallic shield layer that may serve as a floor airplane. As an example, carbon black can make a crosslinked polyethylene cushion layer extra opaque and of a colour that tends to be constant. As an example, an insulation shield layer can optionally be a semi-conductive layer applied over an insulation layer to minimize electrical stresses in a cable. As talked about, the shape of a cushion layer may be substantially circular or of one other form corresponding to, for example, considerably pie shaped the place it might surround a substantially pie formed metallic barrier layer (e.g., a lead (Pb) barrier layer). For example, a barrier layer can be a layer exterior to a shield (e.g., an insulation shield layer) which will aim to provide further safety from corrosive downhole gases and fluids. For example, a cable may carry energy, at occasions, for example, with amperage of as much as about 200 A or more.
In the instance of FIG. 6, the cable 610 with the circular cross-sectional form has an space of unity and the cable 630 with the oblong cross-sectional shape 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 volume and a larger surface space when in comparison with the cable 610. A smaller volume can provide for a smaller mass and, for instance, less tensile stress on a cable which may be deployed a distance in a downhole atmosphere (e.g., on account of mass of the cable itself). For instance, the ability cable 701 can embrace armor the place the cushion layer 760 helps to guard one or more metallic shields from deformation due to power imparted throughout an armoring process and the ability cable 702 can embrace armor the place the cushion layers 760 and/or the cushion layer 762 help to guard a number of metallic shields from deformation due to power imparted during an armoring course of. The data of the plot 1400 confirms that immersing the extruded XLPE movie in water for roughly 12 hours at roughly eighty levels C. is efficient for a fully curing process.
