摘要

ELECTRIC POWER CABLE WITH IMPROVED SCREEN AND METHOD OF MANUFACTURE THEREOF A screen for electric power cables comprising a metal tape with a coating on one side of a thermoplastic with parallel metal wires extending longitudinally of the tape and along non-rectilinear paths partially embedded in the coating and preferably contacting the tape. The tape may also be coated with a plastic on the opposite side with a plastic which will provide good adherence to an insulating sheath. Also, a cable including such screen around the conductor thereof and the insulation on the conductor, and a method for making the screen which comprises heating a so-coated tape, applying the wires to the heated coating in non-rectilinear, parallel paths, pressing the wires into the coating and allowing the latter to cool.
