| 摘要 |
The invention pertains to a method of installing cables (2) in cable ducts (6) using installation devices (1; 1a, 1b, 1c) propelling the cables (2) into the ducts (6). In accordance with the invention, the installation devices (1; 1a, 1b, 1c) are powered by means of pressurized fluid, such as air, transported through the ducts (6). This results in a smaller number of compressors (4) and operators being necessary. For transporting the pressurized fluid, the duct (6) in which a cable (2) is installed and/or parallel ducts may be used. In a duct section (e.g. 6a), the feed direction of the cable (=>) may coincide with, or be opposed to, the transport direction of the fluid (}). The invention further provides installation devices (1) for use in the method. |
