摘要： Disclosed are durable corrosion resistant wellbore electrical cables including a coated electrical conductor, a polymeric protective layer for trapping coating flakes, a first insulating jacket disposed adjacent to the polymeric protective layer and having a first relative permittivity. A second insulating jacket is disposed adjacent to the first insulating jacket and has a second relative permittivity that is less than the first relative permittivity. Another aspect of the invention is a method for manufacturing a cable that includes providing a coated electrical conductor, extruding a polymeric protective layer over the coated electrical conductor, extruding a first insulating jacket over the protective polymeric layer, and extruding a second insulating jacket thereon. Cables of the invention may further include armor wire layers or even current return conductors.

摘要： Disclosed are methods of manufacturing electrical cables. In one embodiment of the invention, method for manufacturing a wellbore cable includes providing at least one insulated conductor, extruding a first polymeric material layer over the insulated conductor, serving a first layer of armor wires around the polymeric material and embedding the armor wires in the first polymeric material by exposure to an electromagnetic radiation source, followed by and extruding a second polymeric material layer over the first layer of armor wires embedded in the first polymeric material layer. Then, a second layer of armor wires may be served around the second polymeric material layer, and embedded therein by exposure to an electromagnetic radiation source. Finally, a third polymeric layer may be extruded around the second layer of armor wires to form a polymeric jacket.
