ABSTRACT:
A low profile electrical cable (10), suitable for use in an oil well where a high temperature corrosive atmosphere is present, and being comprised of a plurality of conductors (12) wherein each conductor is insulated by wrapping it in at least one heat-sealed layer (14) of an insulating material, such as a polyimide plastic. The insulation layer around each conductor is then jacketed by an extruded layer (16) of a material which is mechanically and chemically stable to at least about 400.degree. F. A layer of polyvinyl fluoride tape (18) is disposed around the jacket (16); a braid (20) is wound around the jacket (16) and tape (18) of each conductor to enhance the overall strength characteristics of the cable, and this subassembly is, in turn, further jacketed with a layer (22) of a highly permeable nitrile polymer which provides mechanical and chemical protection for the braid, while preventing gas build-up under the jacket. The insulated and jacketed conductors are then disposed in a side-by-side parallel relationship and wrapped in a metal armor (24), such as galvanized steel. The physical properties of the insulating and jacketing materials allow relatively thin layers to be used for producing a cable which is smaller in overall dimensions than prior cables of comparable electrical capacity.
