Replace a Cable with a Single-Core Cable Assembly - Intergraph Smart Electrical - Help - Hexagon

This procedure explains how to change the structure of plant power cables so that they become single-core cable assemblies. This change happens after you replace the associated reference cable with a reference single-core cable assembly.

1. In the Electrical Index, expand the folder hierarchy Wiring Equipment > Cables.

2. Expand one of the Power Cables cable folders.

3. Select the folder and adjust the size of the panes to view the individual cables in the list view pane.

4. If required, change the view in the list view pane by selecting View Settings to toggle through each view of the items in the list view pane, or select the arrow beside the icon and select the required view.

5. Hold CTRL while selecting the cables that you want to replace.

6. Select Actions > Cables > Replace Cable Structure.

   If the cable you are replacing is a single-core cable assembly, you cannot use this command. Instead, edit the existing cable assembly as required. For details, see Change the Formation of a Single-Core Cable Assembly.

7. On the Replace Cable Structure dialog, do one of the following in the Selected cables grid:

   • For each cable that you want to replace, select the check box beside the cable name.

   • Select the Select all check box if you intend to replace all the cables in the list.

   You cannot replace the reference cable of a plant cable if:

   • the plant cable is wired.

   • the plant cable is installed.

   • the plant cable is locked to a cable drum.

8. Under Change, select the Replace with single-core cable assembly option.

9. Under Select replacement structure, select a reference single-core cable assembly that will replace the associated reference cable in the selected plant cables.

10. If required, select properties under Filter criteria to filter the list of available reference cables.

• In the new assembly, the software creates the constituent phase, grounding, and neutral single-core cables based on the definitions of the selected reference single-core cable assembly. If the constituent grounding and neutral cables belong to the Power category, they will retain the equipment connections of the original cable. If the constituent grounding and neutral cables belong to the Grounding category, they will not retain the equipment connections of the original cable.

• The constituent cables preserve the values of the native cable tag, such as tag sequence, tag prefix, design length, estimated length, tail 1 and tail 2 lengths, and spare length. The only additions are the phase labels, for example L1, L2, L3, etc.

• If there are no cable naming conventions, two cases are possible:

  • Case 1: No cable naming conventions and the native cable has not been renamed:

    • The assembly container tag gets the name of the native cable.

    • The constituent cables get the default cable alias as defined in Options Manager and the cable sequence number of the native cable preceded by the single core cable assembly suffix.

  • Case 2: No cable naming conventions but the native cable has been renamed:

    • The assembly container tag gets the name of the native cable.

    • The constituent cables get the default cable alias as defined in Options Manager and the cable sequence number of the native cable preceded by the single core cable assembly suffix.

  • Example: If you rename CABLE-32 to MyCable (note that 32 is the cable sequence number). After replacing MyCable with a single core cable assembly, the assembly container name becomes MyCable and the constituent cables are named CABLE-32/L1, CABLE-32/L2, etc. and CABLE-32/G1, CABLE-32/N1

• If there are cable naming conventions and you rename a cable before replacing it with a single core cable assembly:

  • The assembly container tag gets the name of the native cable.

  • The constituent cables get their tags based on the naming conventions.

  • Example: If you rename CNC-001 to CABLE-30, the assembly container becomes CABLE-30 while the constituent cables are named CNC-001/L1, CNC-001/L2, CNC-001/L3 and CNC-001/G1, CNC-001/G1.

• The software does not allow you to replace a parallel cable with a single-core cable assembly. Parallel cables do not appear in the Selected cables grid if the Replace with a single-core cable assembly option is active.

• The software does not allow you to replace the reference cable of those cables that have already been wired, installed, or locked to a drum.

• The software does not replace power cables with single-core assemblies if the power cables are assigned to cable drums. If you selected such cables for replacement, the software displays a message at the end of the process informing you of the problem and asking you to open the log file where you can see the exact description of the problem. (Note that drum assignment can be seen on the Design Data tab of the Cable Common Properties dialog box, in the Drum box under Drum assignment. If there is no indication in the Drum box, this means that the cable is not assigned to any cable drum.)

• Note that any existing cable routing is not retained after replacing the cable structure with single-core cable assembly.
