FIG. 18 shows a plot 1800 of DMA measurements (storage modulus versus temperature) for uncured and fully 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 protecting layer generally is a cushion layer that may be an extruded cushion layer that includes XLPE and optionally one or more further supplies (e.g., PP, talc, carbon black, etc.). For instance, an electric submersible pumping system can embrace an electric submersible pump that features an electric motor and a pump; an electric energy supply for providing electricity; and a energy cable disposed between the electric energy supply and the electric motor for supplying electricity from the facility source to the electric motor, where 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 energy cable for supply of electrical energy to the submersible electric motor, the place the ability cable features a conductor, a lead (Pb) barrier layer disposed about the conductor, a cushion layer disposed about the lead (Pb) barrier layer where the cushion layer contains crosslinked polyethylene (XLPE), and metallic armor wrapped about the cushion layer.
For example, a power cable can embrace a conductor; a lead (Pb) barrier layer disposed about 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 concerning the cushion layer where the facility cable is a multiphase, electrical submersible pump power cable. For example, a method can embrace extruding polyethylene that is or that features excessive density polyethylene (HDPE). For instance, a technique can embody extruding polyethylene a couple of lead (Pb) barrier layer disposed a couple of conductor to form an assembly; and armoring at least one of many assemblies with metallic armor to kind a cable the place armoring consists of wrapping the metallic armor immediately over the extruded polyethylene. As an example, a method can include extruding polyethylene a few lead (Pb) barrier layer disposed a couple of conductor to kind an meeting; and armoring at least one of many assemblies with metallic armor to form a cable. For instance, a energy cable can embody an insulation layer that includes EPDM, a lead (Pb) barrier layer and a protective layer that features a crosslinked polyethylene the place the protecting layer might additional embrace polypropylene and/or talc.
Keeping the talc focus constant at approximately 5 wt %, the fluid uptake share decreases strongly with growing the PP focus. FIG. 21 reveals a plot 2100 as to fluid uptake proportion 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 similar to a layer that includes EPDM. FIG. 25 exhibits components of a computing system 2500 and a networked system 2510. The system 2500 consists of a number of processors 2502, memory and/or storage parts 2504, a number of input and/or output gadgets 2506 and a bus 2508. In response to an embodiment, directions may be stored in one or more pc-readable media (e.g., reminiscence/storage components 2504). Such instructions may be learn by a number of processors (e.g., the processor(s) 2502) by way of a communication bus (e.g., the bus 2508), which could also be wired or wireless. According to an embodiment, parts may be distributed, reminiscent of in the community system 2510. The community system 2510 consists of components 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-three could embody reminiscence accessible by the processor(s) 2502. Further, the element(s) 2522-2 may include an I/O machine for show and optionally interplay with a method.
In such an example, the cushion layer can embrace clay and/or polypropylene. In such an instance, the clay could be or include talc. The impact of PP and talc focus on the melt viscosity was examined for control of processing circumstances of XLPE/PP/Talc composites. For instance, processing gear might optionally include a number of types of gear that can be utilized to alter properties of the first materials 2412 and/or the second material 2414 and/or the third material 2416. For example, such equipment could be or include a hot air oven and/or a sizzling liquid bath that may expedite curing, publish-curing, and so on. when one or more of the supplies 2412 and 2416 is passed therethrough. The third materials 2416 can form a cushion layer about the second material 2414. The third materials 2416 can have a hoop stress such that it helps to retain form, which may, in turn, help to retain form of the second material 2414. The third material 2416 can be formulated for at the least some quantity of crosslinking after extrusion by the extruder 2417. For instance, crosslinking can happen no less than in part in situ whereas the assembly formed through the extruder 2417 is waiting to be armored and/or otherwise processed.
