For instance, in embodiments that embrace an HNBR insulation shield layer extruded over an EPDM insulation layer, the insulation shield layer might impart enhanced injury resistance along with improved resista**o well fluids and gases to the cable. As to a braid or a braided layer, numerous kinds of supplies could also be used resembling, for example, polyethyle**erephthalate (PET) (e.g., utilized as a protecting braid, tape, fabric wrap, and so on.). As an example, a colorant could also be an additive. In such an example, a **ductor could also be in a range from about eight AWG (about 3.7 mm) to about 00 AWG (about 9.Three mm). Eight AWG (e.g., OD approx. In the cable 630, the **ductors 632 may be about 7.35 mm (e.g., about 1 AWG) in diameter with insulation of about 2 mm thi**ess, metallic lead (Pb) of about 1 mm thi**ess (e.g., as a gasoline barrier layer), a jacket layer (e.g., the layer 634) over the lead (Pb) of about 1 mm thi**ess at ends of the cable 630, elective armor of about 0.5 mm thi**ess and an non-obligatory polymeric layer of about 1 mm thi**ess (e.g., the layer 636 as an outer polymeric coat). In such an example, the metallic shield layer could serve as a ground aircraft.

For example, a cable may be formed with phases break up out from each other where every phase is encased in strong metallic tubing. In Table 1, the insulation ** embrace a shield that's non-metallic and/or a shield that is metallic. Such a polymeric materials may be utilized for insulating a number of **ductors. As an example, a cable may carry energy, at occasions, for example, with amperage of up to about 200 A or more. As one instance, the cushion layer 760 will be formed of a cloth with a form and size that helps to keep up the shape and dimension of the metallic shield 750. In such an instance, the shapes may be **siderably circular. In the example of FIG. 5, the MLE 500 (or "lead extension") a **ductor 510, a **ductor shield 520, insulation 530, an insulation shield 540 and/or a metallic shield 550, a number of other barrier layers 560, a braid layer 570 and armor 580. While the example of FIG. 5 mentions MLE or "lead extension", it may be carried out as a single **ductor meeting cable for a number of of a variety of downhole uses.

For example, **sider a three part cable that features part assemblies the place every cushion layer of a respective section meeting is coloured differently to establish the corresponding part (e.g., crimson, white, black, inexperienced, and so on.). For instance, an inline longitudinal wrapped fuel impermeable barrier that features a lead (Pb) alloy tape f**as sealing may be disposed about particular person insulated copper **ductors inside a multi-part **ductor assembly. As to the cable armor 480 and 490, metallic or metal alloy may be employed, optionally in multiple layers for improved injury resistance. As an example, manufacture of an inline longitudinal wrapped fuel impermeable barrier may include using with a lead (Pb) alloy (e.g., Pb-Sn-Sb crystal structure) tape. And, added costs may be associated with maintaining a high temperature steam (or sizzling air) tube and/or boilers or nitrogen generators that may feed it. FIG. 7 shows an instance of a power cable 700, an example of a energy cable 701, and an example of a energy cable 702 where the power cable 700, 701 and/or 702 could also be suitable to be used in the system 300 of FIG. 3 or optionally in a number of other programs (e.g., SAGD, etc.).

FIG. 5 exhibits an example of one of many MLEs 500 appropriate to be used in the system 300 of FIG. 3 or optionally one or more different te**iques (e.g., SAGD, and so forth.). FIG. 20 shows a plot 2000 of the class angular frequency dependence of **plex viscosity for XLPE/PP/Talc with different co**rations at roughly 177 degrees C. (identical because the processing temperature). FIG. 12 exhibits a sequence of pictures for two different cables 1200 (left) and 700 (proper). As proven in FIG. 6, the cable 610 includes a circular cross-sectional shape while the cable 630 **tains an oblong cross-sectional shape. As an example, an additional cushion layer could also be applied that surrounds assemblies the place the extra cushion layer is **siderably circular in its cross-sectional shape (e.g., an annular wall about a group of assemblies). The swelling per**tage and diffusion of dog bone shape samples dramatically decreased by including PP. The blend with 50 wt % PP showed better chemical **patibility and decrease swelling than that of 25 wt % PP mix. Extruded XLPE may are inclined to have a low crosslink density, as such, the XLPE may exhibit low chemical **patibility in **trast to fully cured XLPE (e.g., more extremely crosslinked XLPE).
