Building horizontal cable routing method

First, the pipeline wiring

When constructing a building, pipeline wiring is typically pre-installed in the floor during the concrete pouring process. A steel or iron wire is used as a traction cable within the conduit to help guide the cables through later. To ensure accuracy, it's essential to refer to the pipeline drawings during construction, which will help plan the layout and avoid errors.

In new buildings that don't have pre-installed conduits, it's best to coordinate the wiring work with the interior decoration. This approach not only makes installation easier but also maintains the building's aesthetic appeal by keeping cables hidden and organized.

The conduits are usually installed from the wiring closet to the designated information socket location. During the installation of twisted pair cables at the information socket, the cable can be pulled through the conduit from the opposite end, ensuring a smooth and secure connection to the wiring closet.

Second, the ceiling wiring

1. Obtain the construction blueprints and determine the optimal routing for the cables;

2. Open the ceiling along the planned route, carefully pushing each panel aside with both hands;

3. Place multiple cable boxes together, ensuring their outlets face upward for easy access;

4. Label the boxes directly on the carton, and mark the ends of the cables with labels or tags for identification;

5. Attach a suitable length of pulling wire to a reel for ease of use;

6. Begin from the farthest point from the wiring closet and pull the bundled cables through the cable tray, guiding them along the ceiling corridor;

7. Move the ladder closer and continue pulling the cable through the next ceiling hole until the rope reaches the end of the corridor;

8. Pull out the cables from each box, forming a "pair" and securing them with tape;

9. Pass the drawstring through three pairs of taped cables, create a loop, and fasten the bundle to the rope using a strap;

10. Return to the other end of the drawstring and manually pull it. As a result, all six cables (three pairs) will be automatically pulled through the cable tray and into the wiring closet;

11. Repeat step 8 for the next set of cables (another three pairs);

12. Continue adding the remaining cable sets to the drawstring, pulling them forward one by one until the end of the corridor is reached, then proceed to pull the cables all the way to the wiring closet.

Once the ceiling wiring is complete, the cables should be guided down to the information socket via a wall or post pipe. The twisted pair should be tightly wound and inserted into a PVC tube embedded in the wall. Push it down until about 25–30 mm is visible at the socket hole, ensuring a secure and neat connection.
