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 instance, the protective layer can be a cushion layer that can be an extruded cushion layer that includes XLPE and optionally one or more further materials (e.g., PP, talc, carbon black, and so on.). As an example, an electric submersible pumping system can include an electric submersible pump that features an electric motor and a pump; an electric power supply for offering electricity; and a power cable disposed between the electric energy supply and the electric motor for supplying electricity from the power supply to the electric motor, the place the power cable features a protective layer extruded on an outer surface of a lead (Pb) barrier layer. For example, a pump system can embrace a pump; a submersible electric motor operatively coupled to the pump; and a energy cable for supply of electrical power to the submersible electric motor, where the facility cable includes a conductor, a lead (Pb) barrier layer disposed concerning the conductor, a cushion layer disposed in regards to the lead (Pb) barrier layer where the cushion layer contains crosslinked polyethylene (XLPE), and metallic armor wrapped about the cushion layer.

As an example, a power cable can embrace a conductor; a lead (Pb) barrier layer disposed concerning the conductor; a cushion layer disposed about the lead (Pb) barrier layer the place 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 power cable. For instance, a technique can include extruding polyethylene that is or that features high density polyethylene (HDPE). For example, a way can include extruding polyethylene a couple of lead (Pb) barrier layer disposed about a conductor to form an assembly; and armoring not less than one of many assemblies with metallic armor to form a cable the place armoring consists of wrapping the metallic armor straight over the extruded polyethylene. For example, a way can embrace extruding polyethylene about a 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 type a cable. For example, a energy cable can embrace an insulation layer that includes EPDM, a lead (Pb) barrier layer and a protective layer that includes a crosslinked polyethylene where the protecting layer may further embody polypropylene and/or talc.

Keeping the talc concentration constant at roughly 5 wt %, the fluid uptake share decreases strongly with rising the PP focus. FIG. 21 exhibits a plot 2100 as to fluid uptake percentage 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 reminiscent of a layer that features EPDM. FIG. 25 shows parts of a computing system 2500 and a networked system 2510. The system 2500 contains a number of processors 2502, reminiscence and/or storage parts 2504, one or more enter and/or output gadgets 2506 and a bus 2508. According to an embodiment, instructions could also be stored in a number of computer-readable media (e.g., memory/storage parts 2504). Such instructions may be learn by one or more processors (e.g., the processor(s) 2502) via a communication bus (e.g., the bus 2508), which may be wired or wireless. In accordance with an embodiment, components may be distributed, corresponding to within the network system 2510. The network system 2510 contains elements 2522-1, 2522-2, 2522-3, . 2522-N. For example, the components 2522-1 could include the processor(s) 2502 while the part(s) 2522-3 may include reminiscence accessible by the processor(s) 2502. Further, the element(s) 2522-2 might include an I/O gadget for show 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 embody talc. The impact of PP and talc focus on the melt viscosity was examined for management of processing conditions of XLPE/PP/Talc composites. For example, processing gear might optionally include a number of types of gear that can be utilized to change properties of the first material 2412 and/or the second material 2414 and/or the third materials 2416. For instance, such equipment might be or include a sizzling air oven and/or a hot liquid bath that may expedite curing, put up-curing, and so forth. when a number of of the materials 2412 and 2416 is passed therethrough. The third material 2416 can kind a cushion layer in regards to the second materials 2414. The third materials 2416 can have a hoop stress such that it helps to retain shape, which may, in flip, assist to retain shape of the second material 2414. The third materials 2416 may be formulated for a minimum of some amount of crosslinking after extrusion by the extruder 2417. For example, crosslinking can happen at the least partially in situ while the assembly formed through the extruder 2417 is ready to be armored and/or otherwise processed.
