For instance, a considerably circular formed cushion layer could also be extruded about a plurality of substantially pie formed cushion layers which might be grouped. In the examples of FIG. 6, a conductor could also be surrounded by a number of optionally available layers, as generally illustrated through dashed lines. In FIG. 7, the facility cable seven hundred consists of three conductor assemblies where each assembly includes a conductor 710, insulation 730, a metallic shield 750, a cushion layer 760 and an armor layer 780. In FIG. 7, the ability cable seven-hundred is configured with a flat geometry; whereas, the ability cables 701 and 702 are configured with a spherical geometry where conductors are substantially pie formed of their cross-part. In the cable 630, the conductors 632 could also 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, non-obligatory armor of about 0.5 mm thickness and an non-obligatory polymeric layer of about 1 mm thickness (e.g., the layer 636 as an outer polymeric coat).
