As many have said on here many times the sheath should not be considered insulation, it is mechanical protection. The core plastic is insulation, the bedding layer is not, just packing, so the armour is an exposed conductive part even if sheathed. is plastic-coated metal trunking or conduit an exposed conductive part? Yes, because unlike the cores it is not insulation tested with a water bath at manufacture, and whatever YOU do, may have defects you have not noticed. Is this part of an EICR, because this should be a code 2, but is obviously easily fixed with a new metal gland etc. The plastic hoods over glands are not insulation, they can easily be pulled back, they are environmental protection for the armour.
