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： An electrical cable is provided which includes a coated electrical conductor, a polymeric protective layer which traps any coating flakes, a first insulating jacket disposed adjacent to the electrical conductor and having a first relative permittivity. A second insulating jacket disposed adjacent to the first insulating jacket and having a second relative permittivity that is less than the first relative permittivity. In another aspect of the present invention, a method is provided 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.
