FIG. 18 exhibits a plot 1800 of DMA measurements (storage modulus versus temperature) for uncured and totally cured pure XLPE as well as pure PP, uncured XLPE/PP 75/25 and uncured XLPE/PP 50/50 wt % blends. In such an example, the protective layer could be a cushion layer that may be an extruded cushion layer that includes XLPE and optionally a number of extra materials (e.g., PP, talc, carbon black, and many others.). For instance, an electric submersible pumping system can embody an electric submersible pump that features an electric motor and a pump; an electric power source for offering electricity; and a power cable disposed between the electric energy supply and the electric motor for supplying electricity from the ability supply to the electric motor, the place the facility cable includes a protective layer extruded on an outer surface of a lead (Pb) barrier layer. As an example, a pump system can include a pump; a submersible electric motor operatively coupled to the pump; and a power cable for delivery of electrical energy to the submersible electric motor, the place the power cable features a conductor, a lead (Pb) barrier layer disposed in regards to the conductor, a cushion layer disposed in regards to the lead (Pb) barrier layer the place the cushion layer includes crosslinked polyethylene (XLPE), and metallic armor wrapped about the cushion layer.

As an example, a energy cable can include a conductor; a lead (Pb) barrier layer disposed concerning the conductor; a cushion layer disposed concerning the lead (Pb) barrier layer where the cushion layer consists of crosslinked polyethylene (XLPE); and metallic armor wrapped concerning the cushion layer the place the ability cable is a multiphase, electrical submersible pump energy cable. As an example, a way can embody extruding polyethylene that's or that includes high density polyethylene (HDPE). As an example, a method can embody extruding polyethylene a few lead (Pb) barrier layer disposed a couple of conductor to kind an meeting; and armoring at the very least one of many assemblies with metallic armor to type a cable where armoring consists of wrapping the metallic armor immediately over the extruded polyethylene. For example, a technique can include extruding polyethylene a couple of lead (Pb) barrier layer disposed a few conductor to form an meeting; and armoring not less than one of many assemblies with metallic armor to form a cable. For instance, a power cable can include an insulation layer that includes EPDM, a lead (Pb) barrier layer and a protecting layer that features a crosslinked polyethylene where the protecting layer could further embrace polypropylene and/or talc.

Keeping the talc concentration fixed at roughly 5 wt %, the fluid uptake share decreases strongly with rising the PP concentration. FIG. 21 exhibits a plot 2100 as to fluid uptake share with respect to PP-talc wt %. As proven in FIG. 23, the a number of conductors 2310 is(are) insulated with an insulation layer 2330 akin to a layer that includes EPDM. FIG. 25 exhibits elements of a computing system 2500 and a networked system 2510. The system 2500 consists of one or more processors 2502, reminiscence and/or storage elements 2504, one or more enter and/or output devices 2506 and a bus 2508. In response to an embodiment, directions could also be saved in one or more laptop-readable media (e.g., reminiscence/storage parts 2504). Such instructions may be learn by one or more processors (e.g., the processor(s) 2502) through a communication bus (e.g., the bus 2508), which may be wired or wireless. In response to an embodiment, components could also be distributed, such as within the community system 2510. The network system 2510 consists of elements 2522-1, 2522-2, 2522-3, . 2522-N. For example, the parts 2522-1 might embody the processor(s) 2502 whereas the element(s) 2522-3 could embody reminiscence accessible by the processor(s) 2502. Further, the element(s) 2522-2 could embrace an I/O machine for display and optionally interaction with a way.

In such an example, the cushion layer can include clay and/or polypropylene. In such an instance, the clay may be or include talc. The impact of PP and talc focus on the melt viscosity was examined for management of processing circumstances of XLPE/PP/Talc composites. As an example, processing tools may optionally include a number of varieties of tools that can be utilized to change properties of the primary material 2412 and/or the second materials 2414 and/or the third material 2416. For example, such equipment could be or embody a hot air oven and/or a sizzling liquid bath that can expedite curing, publish-curing, and so forth. when a number of of the materials 2412 and 2416 is passed therethrough. The third material 2416 can form a cushion layer about the second material 2414. The third material 2416 can have a hoop stress such that it helps to retain form, which may, in turn, help to retain shape of the second material 2414. The third material 2416 might be formulated for at the very least some quantity of crosslinking after extrusion by the extruder 2417. For example, crosslinking can happen not less than partly in situ while the assembly formed via the extruder 2417 is waiting to be armored and/or otherwise processed.
