Data Transmission Cable and Method for Producing a Data Transmission Cable

A data transmission cable, comprising:

• at least one wire pair with two wires lying parallel to each other, each of said wires having an electrical conductor surrounded by an insulation;
• a foil annularly encasing said wire pair jointly over a length thereof, said foil having an electrically conductive inner side and an electrically insulating outer side;
• said foil having a longitudinal fold exposing a portion of said inner side outwardly;
• and
• an additional wire laid on said foil and contacting said portion of said inner side facing outward.

A method of producing a data transmission cable with at least one wire pair having two wires lying parallel to one another and each being formed of an electrical conductor surrounded by an insulation, the method which comprises:

• providing a foil with an electrically conducting inner side and an electrically insulating outer side;
• forming a longitudinal fold on the foil so that the inner side is directed outward;
• jointly sheathing the wire pair with the foil annularly over a length of the wire pair;
• and
• laying an additional wire onto the foil in contact with the inner side of the foil made to face outward.
