ABSTRACT:
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.
