ARMORED SUBMERSIBLE Power CABLE

FIG. 19 shows a plot 1900 for data from a second heating run for pure PP, uncured pure XLPE, and uncured blends of XLPE/PP 75/25 and XLPE/PP 50/50 wt %. As an example, the processing tools 2405 can deposit insulation as the first material 2412 and can deposit a lead (Pb) barrier materials as the second material 2414. The third materials 2416 can include polyethylene optionally blended with polypropylene and/or talc. For instance, a energy cable can embody an insulation layer that features EPDM, a lead (Pb) barrier layer and a protective layer that features a crosslinked polyethylene the place the protecting layer could additional embrace polypropylene and/or talc. In some embodiments, a power cable could include a number of conductors, an EPDM insulation layer disposed over every conductor, and a lead (Pb) barrier layer disposed over the EPDM insulated conductor(s). A round power cable may be used as energy cable in an electric submersible pumping system. A flat energy cable could also be used as a power cable in an electric submersible pumping system. Such a energy cable can include an armor layer about an outer floor of the protecting layer. For example, a technique can include extruding polyethylene a few lead (Pb) barrier layer disposed a few conductor to type an assembly; and armoring at the very least one of the assemblies with metallic armor to kind a cable.

As an example, a technique can embody crosslinking at the least a portion of polyethylene after armoring and/or crosslinking at the least a portion of the polyethylene before armoring. For instance, a way can embrace extruding polyethylene about a lead (Pb) barrier layer disposed a couple of conductor to form an assembly; armoring at least one of the assemblies with metallic armor to form a cable; and operatively coupling the cable to a submersible electrical motor. Such an armor layer may be a metallic armor that's wound spirally about a number of assemblies (e.g., conductor assemblies).

For example, a crosslinking process may be carried out in stable shaped polymer relatively than in melt. In such an approach, a process can optionally be implemented with out curing of an extruded mix for 12 hours in sizzling water.

Such an approach can be applied optionally without heating the extruded materials in scorching water for hours. The totally cured pattern was ready by immersing the extruded XLPE film into a scorching water at 80 levels C. for 12 hours. For instance, including polypropylene (PP) or PP with talc can improve the mechanical and thermal stability of an extruded XLPE materials. Talc or talcum is a clay mineral composed of hydrated magnesium silicate, for instance, consider a number of of the chemical components H2Mg3(SiO3)four or Mg3Si4O10(OH)2. In line with an embodiment, a number of computer-readable media could embody computer-executable directions to instruct a computing system to output info for controlling a course of. A crosslinking course of could be relatively sluggish, for example, consider circumstances of at the very least 8 hours in scorching water or steam at 80 degrees C. or up to five weeks at room temperature. 170 levels C. for uncured XLPE after annealing the pattern at room temperature for different days. Tests had been carried out for uncured XLPE and XLPE/PP blends with 25 and 50 wt % PP after the chemical compatibility exams in IRM 903 for roughly 70 hours at approximately a hundred and fifty degrees C. Results display that PP can present each thermal and chemical stability for uncured XLPE.

FIG. 18 exhibits a plot 1800 of DMA measurements (storage modulus versus temperature) for uncured and totally cured pure XLPE in addition to pure PP, uncured XLPE/PP 75/25 and uncured XLPE/PP 50/50 wt % blends. As proven in the plot 1800, the blend of XLPE/PP 75/25 wt % has a plateau storage modulus at one hundred fifty levels C. that is similar in magnitude to that of totally cured XLPE; noting that the plateau storage modulus at a hundred and fifty levels C. of XLPE/PP 50/50 wt % is about one order of magnitude higher than that of totally cured XLPE. Within the plot 1800, the storage modulus of pure thermoplastic PP is far larger than each cured and uncured XLPE over the complete vary of temperature. As shown within the plot 2000, the complex viscosity of the pure thermoplastic PP is far decrease than that of the XLPE/PP/Talc composites. The absolutely cured XLPE/PP/Talc composites could have better chemical compatibility and decrease swelling/fluid uptake percentage than pure XLPE. 2522-N. For instance, the elements 2522-1 could embody the processor(s) 2502 while the component(s) 2522-three might include memory accessible by the processor(s) 2502. Further, the element(s) 2522-2 might embody an I/O device for show and optionally interplay with a method.
