Where a lead (Pb) barrier layer thickness can be decreased for a number of assemblies (e.g., conductor assemblies), a discount in mass of a cable may be achieved compared to a braided layer strategy. Talc or talcum is a clay mineral composed of hydrated magnesium silicate, for example, consider one or more of the chemical formulation H2Mg3(SiO3)4 or Mg3Si4O10(OH)2. For example, an XLPE materials can embrace talc to provide extra thermal and chemical stability to uncured XLPE at high temperatures. Such a polymeric materials may be combined with one or more other materials corresponding to, for example, polypropylene (PP) and/or talc. Talc will not be soluble in water, but is slightly soluble in dilute mineral acids. Mohs scale of mineral hardness, based mostly on scratch hardness comparability, defines worth 1 as the hardness of talc. The value of the storage modulus above the melting point is a function of the crosslink density of the fabric. Both samples have substantially the same storage modulus within the temperature range from approximately −70 degrees C. up to roughly one hundred fifteen levels C. The value of storage modulus of the totally cured sample tends to be about one order of magnitude increased than that of uncured sample in the excessive temperature range, increased than the melting point of XLPE.

In the instance of FIG. 13, the XLPE is PolyOne SYNCURE™ S1054A (PolyOne Corporation) ("S1054A material"). As to a silane cure system, in this example a polyethylene grasp batch will be grafted with silane groups which are mixed with a catalyst in an extruder. In the instance of FIG. 23, the a number of conductors 2310 could also be formed from a uncooked conductor materials (e.g., copper) that has been drawn to a normal wire size, annealed, and plated in both a stranded or solid configuration. In such an instance, the one or more cushion layers may be made by extrusion of XLPE (e.g., XPLE thermoset material). The info of the plot 1400 confirms that immersing the extruded XLPE movie in water for approximately 12 hours at approximately eighty degrees C. is efficient for a completely curing process. A crosslinking course of might be comparatively slow, for instance, consider conditions of a minimum of eight hours in hot water or steam at eighty levels C. or up to five weeks at room temperature.

Given the foregoing information, XLPE annealing at ambient situations is achieved in about one month and is achieved in scorching water or steam for 12 hours at roughly 80 levels C. (e.g., to complete the curing course of). A method can embody controlling a production process as to a number of of such parameters to attain a desired amount of crosslinking (e.g., crosslink density of XLPE), for instance, at a sure time during manufacturing of a energy cable, which may have a optimistic influence on a number of subsequent processes of the manufacturing course of for the facility cable (e.g., consider lessening threat of deformation during armoring of the power cable). As an example, one or more cushion layers can reduce danger of lead (Pb) deformation during an armoring course of. An electric submersible pumping system can embody an electric submersible pump that receives electricity from an electric energy source by the use of a energy cable connected there between, the power cable including a protective layer that includes XLPE over a lead (Pb) barrier layer. As an example, a energy cable for use with an electric submersible pumping system can include a conductor, an insulation layer over the conductor, a barrier layer atop the insulation layer, and a protective layer that includes XLPE over the barrier layer.

For instance, a power cable such because the cable seven-hundred of FIG. 7 will be utilized with an electric submersible pumping system. A flat energy cable may be used as a energy cable in an electric submersible pumping system. A system (e.g., a mixture) can embody about 95 phr S1054A and about 5 phr S1000B (e.g., a catalyst batch part). Such a silane cure system might be employed with out an additional crosslinking course of. As to crosslinking, consider the next three approaches as a number of examples: silane cure system, steady vulcanization and electron beam crosslinking. Made by following the SIOPLAS E two-step technology, SYNCURE™ XLPE gives an alternate to organic peroxide, radiation and reactor copolymer crosslinking processes. XLPE is a crosslinked polyethylene with acceptable mechanical, thermal, and dielectric properties. In some embodiments, a flat power cable may embody a number of conductors, an insulation layer disposed over each conductor, a lead (Pb) barrier layer disposed over each insulation layer, a cushion layer of crosslinked polyethylene (XPLE) that may embrace a number of additives which may be included in an extrudate that features polyethylene, and an armor layer. As to excessive temperature performance, the cable 700 of FIG. 12 can exhibit improved excessive temperature performance when in comparison with the cable 1200 of FIG. 12. For example, as the extruded cushion layer 760 could be thicker than the braided layer 1260, the extruded cushion layer 760 can allow for more room for thermal growth, which can assist to stop lead (Pb) from deforming at high temperatures.
