The cable conduit made of thermoplastic material has a channel wall (2) of circular cross-section enclosed with a cable guide channel (3) with channel inner wall (4) and channel outer wall (5). The channel wall has a three-layer structure composed of foamed intermediate layer (7), smooth-surfaced channel inner wall and channel outer wall. The foamed intermediate layer is axially inserted in comparison to stabilizing layer (8). The stabilizing layer of circular cross section is arranged concentrically to common center (M) in comparison to channel inner wall and outer wall. |
