In the instance of FIG. 2, the controller 230 might access a number of of the PIPESIM™ framework 284, the ECLIPSE™ framework 286 marketed by Schlumberger Limited (Houston, Tex.) and the PETREL™ framework 288 marketed by Schlumberger Limited (Houston, Tex.) (e.g., and optionally the OCEAN™ framework marketed by Schlumberger Limited (Houston, Tex.)). A motor could embrace one or more forms of potheads or connection mechanisms. XLPE may be crosslinked after an extrusion course of by the use of publicity to scorching water or steam with assistance from a catalyst (e.g., or via a number of other mechanisms). For instance, stiffness of XLPE might be improved by compounding with mineral or carbon fillers and/or with higher stiffness polyolefins (reminiscent of a polypropylene homopolymer). For instance, a technique can embody making an XLPE materials with a reasonable amount of crosslink density and/or adding a number of supplies that may favorably work together with XLPE and kind a suitable thermally stable composite with high chemical resistance. As an example, crosslinking can contain chemically reacting polyethylene polymer in a method to induce everlasting chemical bonding between polymer chains. As to continuous vulcanization (CV), polyethylene material can embody a peroxide element that generates free radicals, initiating chain-to-chain crosslinking.

Such a silane cure system can be employed with out a further crosslinking process. For a LVD, a VSD unit can embrace a step-up transformer, control circuitry and a step-up transformer whereas, for a MVD, a VSD unit can embrace an built-in transformer and control circuitry. The SPEEDSTAR™ MVD management circuitry is suitable for indoor or outside use and comes customary with a seen fused disconnect swap, precharge circuitry, and sine wave output filter (e.g., integral sine wave filter, ISWF) tailor-made for management and protection of high-horsepower ESPs. 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 factor, programmable load discount (e.g., smooth-stall function), speed management circuitry to maintain constant load or stress, rocking start (e.g., for caught pumps resulting from scale, sand, and many others.), a utility energy receptacle, an acquisition system for the PHOENIX™ monitoring system, a site communication field to help surveillance and control service, a velocity control potentiometer. HDESPs might handle a wide number of fluids and, for instance, as much as about 2% sand, coal, fines and H2S/CO2. For instance, an ESP cable (e.g., ESP energy cable) could also be rated at, for example, about three kV, about four kV, or about 5 kV (e.g., or more) and may have a type issue that is flat or spherical.

As to material of construction, a cable jacket could include a number of layers of EPDM, nitrile, hydrogenated nitrile butadiene rubber (HNBR), fluoropolymer, chloroprene, or different materials (e.g., to supply for resistance to a downhole and/or other atmosphere). Measurements of temperature along the length of the nicely can provide for suggestions, for instance, to understand circumstances downhole of an ESP. For manufacturing specs, lead (Pb) layer structural circumstances similar to creep and fatigue resistance in addition to microstructural stability throughout the service life of a cable are factors for consideration. For connection to a energy cable or motor lead extensions (MLEs), a motor might include a pothead. 2522-N. For example, the elements 2522-1 might include the processor(s) 2502 whereas the component(s) 2522-3 might include reminiscence accessible by the processor(s) 2502. Further, the part(s) 2522-2 might embrace an I/O device for display and optionally interplay with a way. As to manufacturing, the cable seven-hundred of FIG. 12 can exhibit improved manufacturing when compared to the cable 1200 of FIG. 12. For example, the braided layer 1260 could be applied at approximately 18 to 20 toes per minute (e.g., approximately 5.5 to approximately 6.1 meters per minute) while a excessive pace tape wrapping machine can course of a cable at approximately 100 to 200 toes per minute (e.g., approximately 30.5 to roughly sixty one meters per minute).

As to high temperature performance, the cable seven-hundred of FIG. 12 can exhibit improved high temperature performance when compared to the cable 1200 of FIG. 12. For example, because the extruded cushion layer 760 will be thicker than the braided layer 1260, the extruded cushion layer 760 can enable for more room for thermal expansion, which might help to prevent lead (Pb) from deforming at high temperatures. Armor might be provided as a strip that is wrapped about a number of insulated conductors that can each embrace a person lead (Pb) layer. The armor wrapping process applies power. For instance, the ability cable 701 can embody armor where the cushion layer 760 helps to protect a number of metallic shields from deformation resulting from pressure imparted throughout an armoring process and the facility cable 702 can include armor the place the cushion layers 760 and/or the cushion layer 762 help to protect one or more metallic shields from deformation as a consequence of power imparted during an armoring course of.
