This dialog allows you to do one of the following:

  • Replace the reference cable of selected plant cables. Note that all the selected cables must belong to the same cable category.

  • Replace the reference cable of selected plant power cables with a reference single-core cables assembly. Instead of the selected plant power cable, the software creates a new assembly of cables in the Electrical Index. The name of the new single-core cable assembly will be the same as the name of the power cable that it replaces. The names of the individual power cables in the assembly will be according to the naming conventions set for your plant.

Selected cables

Displays the plant cables that you have selected in the Electrical Index. Select the check box beside each cable whose reference cable you want to replace.

  • The software does not allow you to replace a parallel cable with a single-core cable assembly. Parallel cables are not shown in this grid if under Change you select the Replace with a single-core cable assembly option. If you select the Reference cable option, only the first cable in the parallel set appears in the grid.

  • You cannot replace a single-core cable assembly with another single-core cable assembly using this dialog. Instead, this is done by editing the existing cable assembly. See Change the Formation of a Single-Core Cable Assembly.

  • 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.

Change

Allows you to instruct the software to replace the associated reference cable with another reference cable or with a reference single-core cable assembly.

Reference cable

Instructs the software to replace the associated reference cable with another reference cable.

Replace with single-core cable assembly

Instructs the software to replace the associated reference cable with a reference single-core cable assembly.

Filter by

Allows you to select a set of criteria to filter the available reference cables or reference single-core cable assemblies from which you select to replace the existing reference cable. The options vary depending on your Change selection above.

Cable category

Displays the category that defines the purpose for which the cable is used, that is, power, control, grounding, or instrumentation. The category depends on the folder from which you selected the cables and is read-only. (Available only when the Change option is Reference cable.)

The software replaces cables of the same category. For example, you can only replace a power cable with another power cable.

Cable specification

Allows you to select a specification that defines a family of cables, each consisting of a specific group of reference cables. (Available only when the Change option is Reference cable.)

Conductor arrangement

Allows you to select an option that defines the number and arrangement of the conductors required. Only those reference cables that correspond to the selected conductor arrangement appear.(Available only when the Change option is Reference cable.) The following standard options are available:

Single core cable

Selects current-carrying cables with a single core.

2-core cable

Selects cables with two current-carrying conductors and no additional conductors.

2+1-core cable

Selects cables with two current-carrying conductors and one additional conductor.

3-core cable

Selects cables with three current-carrying conductors and no additional conductors.

3+1-core cable

Selects cables with three current-carrying conductors and one additional conductor.

3+2-core cable

Selects cables with three current-carrying conductors and two additional conductors.

Multicore cable

Selects cables with multiple conductors.

Size

Allows you to select a predetermined cable size. Only those reference cables that correspond to a selected cable size appear. (Available only when the Change option is Reference cable.)

Phase arrangement

Allows you to select a predetermined phase arrangement. . Only those reference single-core cable assemblies that correspond to the selected phase arrangement appear. (Aavailable only when the Change option is Replace with single-core cable assembly.)

Select replacement structure

Allows you to select an appropriate reference cable or a reference single-core cable assembly that will replace the associated reference cable of the plant cables that you selected in the Selected cables grid. Note that the display is filtered according to your selections above. Also, the display varies depending on your Change selection.

Cable Tag

Displays the name of the reference cable that you want to use as the replacement. (Available only when the Change option is Reference cable.)

Cable Formation

Displays the cable formation (number and size of conductors)of the reference cables shown in the grid. (Available only when the Change option is Reference cable.)

Conductor Material

Displays the conductor material of the reference cables shown in the grid. (Available only when the Change option is Reference cable.)

Conductor Arrangement

Displays the conductor arrangement of the reference cables shown in the grid. (Available only when the Change option is Reference cable.)

Cable Assembly Name

Displays the name of the reference single-core cable assembly that you want to use as the replacement. (Available only when the Change option is Replace with single-core cable assembly.)

Phase Arrangement

Displays the phase arrangements of the reference single-core cable assemblies shown in the grid. (Available only when the Change option is Replace with single-core cable assembly.)

Description

Displays the descriptions of the reference single-core cable assemblies shown in the grid. (Available only when the Change option is Replace with single-core cable assembly.)

Note the following when using another reference cable to replace an associated reference cable:

  • The software only allows the replacement of cables belonging the same category. For example, you can only replace a power cable with another power cable.

  • The software does not allow you to replace a reference cable associated with a terminated plant cable unless the new reference cable has the same conductor arrangement as the replaced reference cable.

  • The software does not allow you to replace cables that have already been installed or locked to a drum.

  • After replacing the associated reference cable, the software removes the plant cable from the associated cable drum.

  • The software replaces the values of the selected plant power cables with the property values in the reference cable that you select in the Select replacement structure grid.

  • Note that the properties that will be updated are set in Options Manager. You can make these settings if you have appropriate access rights. In Options Manager, select Options > Set Cable Properties for Synchronization. See Set Cable Properties for Synchronization in the Options Manager help.

  • When the selected cables for replacing include parallel cables, only one tag per parallel cable appears in the display; however the software performs the operation for all the parallel cables in each set. If descriptions exist for the individual parallel cables, the software retains those descriptions.

  • When replacing a group of parallel cables generated by the sizing procedure with cables that have a different formation, make sure that for the Reference cable property, you select Non-sized power cable. Otherwise, you can only replace parallel cables with another group of cables that have the same formation. For example, you can only replace three parallel cables of 300 mm2 (3*300 mm2) with another configuration of 3 parallel cables, such as 3*90 mm2, 3*(3*25 mm2+1*10 mm2), and so forth.

  • The software retains any existing connections with electrical equipment when replacing the reference cable with another reference cable.

  • The software retains any existing cable routing.

Note the following when using a reference single-core cable assembly to replace an associated reference cable:

  • 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.
