Enables you to define the cable drum sizes, routing, length, and so forth. An asterisk beside a property name indicates required data.

Drum definition

Allows you to define cable drum parameters that are used to assign plant cables to drums. After you assign a reference cable to a particular drum, the software uses these values for manual and automatic cable assignment to drums.

When assigning cables to drums manually, you associate a drum with a specific reference cable. You can define multiple drum sizes for each reference cable. These drum sizes are based on various cable lengths that a drum can hold. After you associate a drum with a reference cable that has multiple drum sizes, you can select the most appropriate drum size for a particular drum.

When assigning plant cables to drums automatically, the software optimizes the cable assignment. Smart Electrical optimizes this assignment based on the drum sizes, the maximum percentage of free cable length on the drums and the scrap cable length that you have defined for each reference cable that you select for drum assignment. See Optimization of Cable Drum Assignment and Define Manual Cable Cuts.

You perform automatic cable assignment by using the Assign Drums to Cables wizard. When using the wizard, you define the assignment parameters by selecting the following:

  • All the available reference cables or just one specific reference cable.

  • One or more pulling area.

The wizard will then assign all the plant cables that comply with these parameters. Furthermore, the software will optimize cable assignment to the drums based on the drum sizes, the maximum percentage of free cable lengths on the drums, and the scrap cable length that you have defined for each reference cable that you selected in the wizard.

Drum sizes

Allows you to define multiple sets of cable lengths that will be used in cable drum assignment. Note that all the values that you enter in this grid become available on the Drum Sizes dialog when setting a reference cable for a cable drum.

Minimum

Allows you to type a value and select an appropriate unit of measure for the minimum length of cable when ordering from a supplier.

Maximum

Allows you to type a value and select an appropriate unit of measure for the maximum drum capacity. This value is the total cable length that a drum can hold, including any spare cable.

Remove

Deletes a row that you select.

Maximum free length on drum (%)

Allows you to type a value which sets the maximum percentage of free space that can be left on a drum. A drum that has more free space than the value you set here makes the drum not optimized. Note that this option is applicable to automatic cable assignment only. The software indicates if a drum is not optimized in the cable drum log file.

Scrap cable length

Allows you to specify the scrap length for the cables that are based on the current reference cable. The software will use this value when calculating the total cable length on a drum in your plant. Note this value has no effect on any other calculations.

Cable routing

This information only applies to plant cables.

Design data

Provides information about the physical characteristics of the cable.

Use external routing length

This information only applies to project cables.

Estimated length

Allows you to enter the estimated length of cable before installation for use as a default value in project cables.

Design length

Allows you to enter a more accurate length for the cable after installation for use as a default value in plant cables.

Routing length

This information only applies to plant cables.

External routing length

This information only applies to plant cables.

Tail 1

Type a value for the spare tail length at one end the cable, if you require, for use as a default value in plant cables.

Length

A calculated field that displays the design length, or if not available, the estimated length.

Tail 2

Type a value for the spare tail length at the other end the cable, if you require, for use as a default value in plant cables.

Spare length

Type a value for additional spare cable length, if you require, for use as a default value in plant cables.

Actual length

This information only applies to plant cables.
