Such a pothead could, for example, provide for a tape-in reference to steel-to-steel seals and/or steel-to-elastomer seals (e.g., to provide a barrier against fluid entry). For connection to a energy cable or motor lead extensions (MLEs), a motor may include a pothead. For instance, a pothead unit may be supplied as a separate unit configured for connection, instantly or indirectly, to a motor housing. For example, a motor housing may embody slot liners. A motor could embody a number of sorts of potheads or connection mechanisms. In such an example, the additives could impart properties that facilitate manufacturing of a cable (e.g., or an meeting for a cable) earlier than a desired amount of polyethylene crosslink has occurred submit-extrusion. In some flat power cable embodiments, two or extra particular person coated conductors could be organized in a aspect-by-side configuration (e.g., a 2×1, 3×1, or 4×1 configuration) and an armor layer will be utilized over a jacket. Lead (Pb) exhibits good impermeability to moisture, corrosion resistance, and processability as a protective barrier layer. In the cable 630, the conductors 632 could also be about 7.35 mm (e.g., about 1 AWG) in diameter with insulation of about 2 mm thickness, metallic lead (Pb) of about 1 mm thickness (e.g., as a gasoline barrier layer), a jacket layer (e.g., the layer 634) over the lead (Pb) of about 1 mm thickness at ends of the cable 630, elective armor of about 0.5 mm thickness and an optionally available polymeric layer of about 1 mm thickness (e.g., the layer 636 as an outer polymeric coat).

In other embodiments, an insulation shield layer could also be tandem extruded with an insulation layer. For instance, adding polypropylene (PP) or PP with talc can improve the mechanical and thermal stability of an extruded XLPE materials. As to crosslinking, a course of can include controlling one or more parameters to attain a desired crosslinking fee and/or a desired crosslink density of a material that includes polyethylene and optionally one or more of talc and polypropylene. The electrical windings may be formed from magnet wire that features an electrical conductor and a minimum of one polymeric dielectric insulator surrounding the electrical conductor. As talked about, an ESP cable that features a cushion layer might permit for lower cost, higher processing velocity, and improved efficiency. For example, a cushion layer can embody one or more colorants. Lead (Pb), at ambient temperature, can have a density that is approximately 11.34 g/cm3. For example, manufacture of an inline longitudinal wrapped gas impermeable barrier could embody using with a lead (Pb) alloy (e.g., Pb-Sn-Sb crystal structure) tape. In such an instance, the respective lead (Pb) barrier layers of the assemblies (see, e.g., low voltage armored power cable the lead (Pb) barrier layer 1050) develop into distorted accompanied by some loss of symmetry.

FIG. 11 exhibits example graphics as to some quantity of compression and extension of an meeting 1001 with no cushion layer in comparison with less compression and extension of an meeting 705 with a cushion layer 760. As indicated in FIG. 11, a number of dimensions and/or shapes could also be utilized to characterize an amount of deformation of an assembly, significantly an quantity of deformation of a lead (Pb) barrier layer of an assembly. In the example of FIG. 9, the edge 784 might be in direct contact with the cushion layers 760-1, 760-2 and 760-3 where bending may happen of the armor 780 with pressure against a number of of the layers 760-1, 760-2 and 760-three where the layers 760-1 and 760-3 could obtain a better quantity of the power than the layer 760-2. Thus, indentation risk will be better for the layers 760-1 and 760-3, which may be considered the outermost layers. While the example of FIG. 2 shows an ESP which will include centrifugal pump phases, one other type of ESP could also be managed. For example, an ESP may include a hydraulic diaphragm electric submersible pump (HDESP), which is a positive-displacement, double-acting diaphragm pump with a downhole motor. For example, cable armor may be constructed from a number of of a wide range of materials together with, however not restricted to, one or more of galvanized steel, stainless steel, MONEL™ alloy, or another steel, metal alloy, or non-metallic resistant to downhole circumstances.

The VSD unit 270 could include commercially obtainable management circuitry such as the SPEEDSTAR™ MVD management circuitry marketed by Schlumberger Limited (Houston, Tex.). The SPEEDSTAR™ MVD management circuitry can embrace a plug-and-play sine wave output filter, a multilevel PWM inverter output, a 0.Ninety five energy issue, programmable load reduction (e.g., soft-stall function), pace control circuitry to maintain constant load or stress, rocking begin (e.g., for caught pumps ensuing from scale, sand, and so on.), a utility energy receptacle, an acquisition system for the PHOENIX™ monitoring system, a site communication box to help surveillance and control service, a velocity management potentiometer. The SPEEDSTAR™ MVD control circuitry is appropriate for indoor or out of doors use and comes normal with a seen fused disconnect swap, precharge circuitry, and sine wave output filter (e.g., integral sine wave filter, ISWF) tailored for management and protection of high-horsepower ESPs. As proven, the MLEs 500 connect with a motor block 315, which could also be a motor (or motors) of a pump (e.g., an ESP, etc.) and be controllable via the VSD/step-up transformer block 370. In the example of FIG. 3, the conductors of the MLEs 500 electrically connect at a WYE level 325. The circuitry block 350 may derive energy by way of the WYE point 325 and may optionally transmit, receive or transmit and receive knowledge via the WYE point 325. As shown, the circuitry block 350 could also be grounded.
