Abstract
Electrical conductors having an insulation layer comprising a thermosetting elastomeric composition capable of imbibing low molecular weight hydrocarbon well fluids when under pressure and rapidly desorbing the fluids when pressure is removed, and surrounded by a confining braid layer are able to withstand use in gassy oil wells without consequent depressurization-caused rupture failures. Armored electrical cables formed from these insulated conductors without an elastomeric jacketing are suitable for use in powering electric motors in oil wells that have particularly high proportions of gassy hydrocarbons under pressure without undergoing rupture failure.
