The third materials 2416 can kind a cushion layer concerning the second materials 2414. The third materials 2416 can have a hoop stress such that it helps to retain shape, which can, in flip, assist to retain shape of the second material 2414. The third materials 2416 will be formulated for no less than some quantity of crosslinking after extrusion by the extruder 2417. For example, crosslinking can happen at least partially in situ while the meeting formed through the extruder 2417 is waiting to be armored and/or otherwise processed. As an example, processing equipment could optionally embody a number of forms of equipment that can be utilized to alter properties of the first material 2412 and/or the second material 2414 and/or the third materials 2416. For instance, such equipment could be or embody a hot air oven and/or a scorching liquid bath that can expedite curing, publish-curing, etc. when a number of of the supplies 2412 and 2416 is passed therethrough. Hydrocarbon wells have a tendency to incorporate some amount of moisture and cable operating temperatures often exceed eighty degrees C. Under such situations, the aforementioned braid material can degrade and can even dissipate relatively rapidly after installation in a hydrocarbon well.

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, where the facility cable features a conductor, a lead (Pb) barrier layer disposed concerning the conductor, a cushion layer disposed about the lead (Pb) barrier layer where the cushion layer includes crosslinked polyethylene (XLPE), and metallic armor wrapped about the cushion layer. A power cable can embody 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 consists of crosslinked polyethylene (XLPE); and metallic armor wrapped concerning the cushion layer. A method can include extruding polyethylene a couple of lead (Pb) barrier layer disposed about a conductor to form an meeting; and armoring at the very least one of many assemblies with metallic armor to type a cable. Lead (Pb) can creep, which is gradual plastic deformation of a material under a constant stress. In some examples, a lead (Pb) sheath may include comparatively small quantities of one other material resembling, for example, one other metallic or metals that may type an alloy or alloys. An extruder can force materials through a die or dies.

Various kinds of environmental conditions can harm tools. For instance, the geologic setting 140 may be outfitted with equipment 145, which could also be, for instance, steam assisted gravity drainage (SAGD) equipment for injecting steam for enhancing extraction of a resource from a reservoir. With a purpose to introduce sufficient heat to completely activate the peroxide curative, after extrusion an assembly will be sent by way of a excessive pressure steam or sizzling nitrogen containing tube. Given the foregoing information, XLPE annealing at ambient circumstances is achieved in about one month and is achieved in scorching water or steam for 12 hours at approximately eighty levels C. (e.g., to complete the curing process). As used herein, the phrases "up" and "down"; "upper" and "lower"; "top" and "bottom"; and other like phrases indicating relative positions to a given level or factor are utilized to extra clearly describe some components. Further, the terms "couple", "coupling", "coupled", "coupled together", and "coupled with" are used to mean "directly coupled together" or "coupled collectively by way of a number of elements". As used herein, the phrases "connect", "connection", "connected", "in connection with", and "connecting" are used to imply "in direct connection with" or "in connection with by way of one or more elements"; and the time period "set" is used to imply "one element" or "more than one element".

This abstract is supplied to introduce a collection of ideas that are additional described beneath within the detailed description. Features and advantages of the described implementations will be extra readily understood by reference to the following description taken along with the accompanying drawings. Such drive can weaken the gas barrier layer and cause it to rupture. In the cable 630, the conductors 632 may be about 7.35 mm (e.g., about 1 AWG) in diameter with insulation of about 2 mm thickness, metallic lead (Pb) of about 1 mm thickness (e.g., as a gas barrier layer), a jacket layer (e.g., the layer 634) over the lead (Pb) of about 1 mm thickness at ends of the cable 630, optional armor of about 0.5 mm thickness and an non-compulsory polymeric layer of about 1 mm thickness (e.g., the layer 636 as an outer polymeric coat). For example, a metallic shield layer may be utilized over an insulation shield layer. In some embodiments, an insulation shield layer is extruded over an insulation layer. For instance, a minimum manufacturing wall thickness of the metallic lead (Pb) barrier layer may be specified (e.g., from about 20 mils to about 60 mils or about 0.5 mm to about 1.5 mm) that goals to help guarantee efficient protection from corrosive gases.
