PURPOSE: Insulated electrical cables which are suitable for use in gasoline fuel tanks comprise a stranded conductor which is blocked by a polysulfide and is covered by polyamide insulation. CONSTITUTION: An insulated cable which is suitable for use in gasoline fuel tanks, comprises (1) a conductive core which comprises (a) a stranded wire composed of a plurality of elongate conductors, and (b) a solid, polymeric blocking material which fills the interstices between the conductors, at least 50% by weight of the blocking material being a polysulfide; and (2) a polymeric insulating jacket which surrounds the core and is in intimate contact with the core so that gasoline cannot travel along the core, at least the outer surface of said insulating jacket being composed of an insulating material comprising at least 50% by weight of a polyamide. |
