As such, talc might be scratched by a fingernail. For example, a filler will be or embrace talc. However, alternatively, the modulus considerably elevated and the pressure decreased by adding PP and talc. However, in each approaches, armoring can nonetheless distort a lead (Pb) layer. Where a cable includes polypropylene insulation adjacent to a copper conductor, a lead (Pb) layer may be placed over the polypropylene insulation, which may improve its temperature rating (e.g., from about 96 degrees C. to about 125 levels C.). Where a cable consists of EPDM insulation adjacent to a copper conductor, a lead (Pb) layer may be placed over the EPDM insulation and a fabric tape or a braid (e.g., a braided fiber) may be positioned over the lead (Pb) layer as a producing help to minimize distortion of the lead (Pb) layer throughout armoring. To scale back this damage, as mentioned, a taped or braided fiber layer will be applied over a lead (Pb) layer to supply resistance to damage from the armoring process.

In some embodiments, a energy cable may include one or more conductors, an EPDM insulation layer disposed over every conductor, and a lead (Pb) barrier layer disposed over the EPDM insulated conductor(s). The cushion layer 760 could be product of one or more extruded supplies that may persist in a downhole setting of a hydrocarbon effectively over a longer time period than nylon or polyethylene terephthalate string, which might help to maintain lead (Pb) layer protection. As an example, a crosslinking agent may also help to facilitate crosslinking of polyethylene to kind a crosslinked polyethylene (XLPE). For instance, a curative may be or embrace a crosslinking agent (CL agent). For instance, formulating might occur (e.g., wholly or partly) at an extruder site where, for instance, materials are combined prior to introduction to an extruder feeder bin. FIG. 8 reveals an example of a method 810 that features a formulation block 812 for formulating a cloth (e.g., a mixture of materials), an extrusion block 816 for extruding the formulated material, a formation block 820 for forming a cable that may be an armored cable and a utilization block 824 for using the formed cable. In the example of FIG. 8, a provision block could also be included where a pre-formulated material is provided in a type that could be fed to an extruder to perform the extruding of the extrusion block 816. For example, the formulating of the formulation block 812 could also be carried out wholly or partly by a supplier that may supply a wholly formulated material and/or a partially formulated material.

In the example of FIG. 8, the formulation block 812 can formulate the material by use of a number of polymeric supplies (e.g., polyethylene and optionally, additionally polypropylene) and one or more further materials equivalent to, for instance, a number of fillers and/or a number of curatives. For instance, a power cable can embody a conductor; a lead (Pb) barrier layer disposed concerning the conductor; a cushion layer disposed concerning the lead (Pb) barrier layer the place the cushion layer contains crosslinked polyethylene (XLPE); and metallic armor wrapped concerning the cushion layer the place the ability cable is a multiphase, electrical submersible pump energy cable. Such a cable may be known as a energy cable. Lead (Pb) may be included in a cable as an extruded protective layer, which could also be known as a lead (Pb) barrier or lead (Pb) barrier layer. For instance, an electric submersible pumping system can embody 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 ability supply to the electric motor, where the facility cable features a protective layer extruded on an outer floor of a lead (Pb) barrier layer.

As an example, a energy cable to be used with an electric submersible pumping system can embrace a conductor; an insulation layer disposed on an outer surface of the conductor; a barrier layer disposed on an outer floor of the insulation layer; and a protective layer disposed on an outer floor of the barrier layer. In such an instance, the tactic can embrace submersing the submersible electrical motor and powering the submersed electrical motor through electrical power equipped to the cable. For instance, in the strategy 810 of FIG. 8, crosslinking of polyethylene can occur to some amount (e.g., a desired amount) post extrusion per the extrusion block 816. For example, throughout the formation of the cable per the formation block 820 and/or through the utilization of the cable per the utilization block 824, some amount of crosslinking could happen. The a number of processors might execute such directions to implement (wholly or partially) a number of attributes (e.g., as a part of a method). XLPE could also be crosslinked after an extrusion process by way of exposure to scorching water or steam with the help of a catalyst (e.g., or via one or more different mechanisms). In such an strategy, a process can optionally be applied with out curing of an extruded blend for 12 hours in scorching water.
