Number of Cables

In congested areas (such as a downtown network), some utilities use multiple cables per phase to spread the load. For example, a three-phase conductor might actually have multiple cables per phase (3 cables for A, 3 for B, and 3 for C). Conduit Manager allows you to represent multiple cables per phase with the “Number of Cables” field. To change the number of cables, follow these steps:

1. Ensure the conductor is associated to the conduit. See the help topic Associate Conductor to Duct.

2. If necessary, open the ArcFM Conduit Association Editor.

   1. Select the conduit.

   2. On the ArcFM Attribute Editor > Selection tab, right-click the conduit and choose Edit Conduit Associations.

3. Expand the Duct Position that contains the conductor with multiple cables. In the following example, a three-phase conductor is inside duct Position 1.

   

4. Click the conductor once to highlight it in blue.

5. Under Number of Cables, click the plus and minus signs to increase or decrease the number of cables. You can also type in the number.

   

6. Notice the count appears by the conductor inside the duct.

   

7. If each phase occupies a different duct, click Break into Phases. Notice the cable counts now appear by the individual phases.

   

8. Click and drag each phase into its appropriate duct position.

   

9. Click OK to close the ArcFM Conduit Association Editor dialog.
