Wire and cable having integrally formed jacket and partitioned wall members and process and apparatus for making the same

An NM-B electrical cable, the cable comprising:

• a bare grounding conductor;
• an insulated conductor;
• a jacket comprised of a material, wherein the jacket encapsulates the bare grounding conductor and the insulated conductor;
• a wall integrally formed with the jacket;
• wherein the wall separates the bare grounding conductor and the insulated conductor, the wall extends from one portion of the jacket to another portion of the jacket and extends the entire length of the NM-B electrical cable, and wherein the jacket and wall are comprised of the same material and wherein a free space exists between the insulated conductor and the wall.

An NM-B electrical cable, the cable comprising:

• a jacket comprised of a material;
• a bare grounding conductor encapsulated by the jacket;
• a first insulated conductor encapsulated by the jacket;
• a second insulated conductor encapsulated by the jacket;
• a first wall integrally formed with the jacket, wherein the first wall separates the bare grounding conductor and the first insulated conductor, wherein the first wall extends from one portion of the jacket to another portion of the jacket and extends the entire length of the NM-B electrical cable, wherein the jacket and first wall are comprised of the same material, and wherein the first wall forms a first and second chamber inside the jacket;
• a second wall integrally formed with the jacket, wherein the second wall forms a third chamber inside the jacket;
• and
• wherein the first insulated conductor is located in the first chamber, the bare grounding conductor is located in the second chamber, and the second insulated conductor is located in the third chamber.
