Allows you to define and edit basic cable drum properties, and to assign plant cables to the current cable drum. An asterisk beside a property name indicates required data.
Drum tag
Identifies the cable drum. The drum tag appears beside the cable drum in the Electrical Index.
Procurement status
Allows you to set a procurement status for the current drum. The following statuses are available:
In bids
Puts no restrictions on the current drum or the cable that is assigned to this drum.
Ordered
Instructs the software to do the following:
-
You cannot delete the current drum.
-
You can no longer change the Total cable length to order/delivered value. This value becomes unavailable for editing.
-
It is possible to reassign this drum to another cable or add another cable to this drum as long as the Total cable length to order has not been exceeded.
Delivered
Defines the drum as delivered to the construction site. Prevents you from editing the Total cable length to order/delivered value.
Spare drum
Allows you to define the current drum as spare. Defining a cable drum as spare entails the following:
-
The cable drum becomes reserved and the software does not assign it to any cable.
-
You cannot delete a spare cable drum.
-
You cannot modify the Total cable length to order value.
-
You cannot define a drum as spare if it is assigned to a cable. You have to cancel all the cable assignment by selecting Remove in the Assigned cables group box.
Description
Allows you to type a description of the cable drum, for information only.
Reference cable
Displays the reference cable that you selected for the current cable drum. ou must
select a reference cable for the drum. To set a reference cable or to select a different
one, select 
to open the Select Reference Cable Dialog . Note that you can only select a different reference cable if the drum has no assigned
cables.
You can change the drum capacity of a drum even if the drum is assigned to a cable.
This way you can implement new drum capacities supplied by vendors. You can edit the
properties of the associated reference cable and add or change the drum capacity values
for that reference cable. After ve added new Minimum and Maximum values or changed the existing Minimum and Maximum values of the associated reference cable, Select to open the Select Reference Cable dialog and then select Select to set a different drum capacity for a drum regardless of whether the drum has or
has not been assigned to a cable.
Pulling area
Allows you to select a single cable pulling area to which you assign the drum. After you define an appropriate reference cable and select a pulling area, after selecting Add in the Assigned cables data window below, the software can find only those cables that are associated with the currently selected pulling area. If you want to assign cables that belong to multiple pulling areas, select the Allow multiple pulling areas check box, which makes the Pulling area list unavailable. Also note that you can only select another pulling area if the drum has no assigned cables. You can define and customize pulling areas in the Data Dictionary Manager.
Minimum cable length to order
Displays the minimum length of cable when ordering from the supplier. The software enters this value automatically after you select an appropriate reference cable. This value is taken from the Design Data tab of the Reference Cable Common Properties dialog.
Maximum drum capacity
Displays the maximum total cable length that this drum can hold, including any spare cable. The software enters this value automatically after you select an appropriate reference cable. This value is taken from the Design Data tab of the Reference Cable Common Properties dialog. The software validates the total cable length on the drum against this value.
Total cable length to order/delivered
Allows you to specify the length of cable to order from a supplier for future assignment. This value must lie between the minimum cable length to order and the maximum drum capacity and cannot be less than the total cable length on the drum. Note that this value becomes unavailable for editing after changing the procurement status to Ordered. After the procurement status is set to Ordered, the software takes into account the Total cable length to order/delivered value in all relevant calculations.
Total actual length assigned (planned)
Displays the sum of the actual planned length values of all the assigned cables.
Spare percentage on drum
Allows you to specify a spare percentage for the current drum. This value is used by the software to calculate a spare cable length factor, for example, to make allowance for cutting errors. For example, if you want a drum spare factor of 5%, type 5. See Rules Governing Cable Drum Calculations.
Scrap cable length
Displays the scrap cable length value that is used by the software to calculate the Total cable length on drum value. You can define the cable scrap length only for reference cables. This value will be used by the software only for drum calculation purposes and will not be added to the actual cable length of the plant cables.
Total cable length on drum (planned)
Displays the total planned length of the assigned cables on the current drum. The software calculates this value by adding up the Total actual length assigned (planned), Spare percentage on drum, and Scrap cable length values of the current drum. You can assign more cables to this drum so long as this value does not exceed the value of the Maximum drum capacity property.
Total cable length left on drum
Displays the remaining total length of the cables on the current drum after the cables have been installed. The software calculates this value by subtracting the total length of the installed cables from the Total cable length to order/delivered value.
Assigned cables
Displays the cables assigned to the current cable drum. Note that you can only assign cables after you have selected a reference cable and a pulling area.
Locked
Allows you to lock a cable to the current drum. Note that locking a cable to a drum makes it impossible to unassign this cable from the assigned drum or change the assignment to another cable drum. You can unlock the drum from the current cable by clearing the Locked check box here or clear the Lock to drum check box on the Design Tab of the Cable Common Properties dialog.
When using the Assign Drums to Cables wizard, the software optimizes the assignment of cables to drums. The optimization
mechanism disregards all the cables that either have been locked to drums or already
have been installed. Installed and locked cables are, therefore, fixed on those drums.
When calculating the Total cable length left on drum value, the optimization mechanism subtracts the length of the locked and installed
cables from the maximum drum capacity. See Optimization of Cable Drum Assignment.
Tag name
Identifies the cable. The tag name appears beside the cable in the Electrical Index.
Installation Status
Displays whether the cable is installed in the field or not. If the cable is installed, the software takes its Actual Length value to calculate the Total cable length left on drum value.
Formation
Describes cable structure in terms of the number of conductors, and where appropriate, additional conductors with their sizes. For example, 3 x 2.5 mm2 + 2 x 1.0 mm2 described a cable with three 2.5 mm2 main conductors and two 2.5 mm2 additional conductors.
Actual Length
A derived value for cable length. If in the Cable Common Properties dialog a cable has a value for Estimated length, but no value for Design length, then the estimated length is the value for Actual Length. If there is a value for Design length, then this is also the value for Actual Length.
Allow multiple pulling areas
When assigning cables to the current drum, select to instruct the software to look for all available cables that belong to the selected reference cable. If you do not select this check box, you need to select an appropriate pulling area from the Pulling area list. After you define an appropriate reference cable and allow multiple pulling areas, after selecting Add in the Assigned cables data window below, the software finds all the cables that belong to the current reference cable and not just those cables that are assigned to one specific pulling area.
Add
Opens the Find dialog, where you search for available cables to assign to the current cable drum. The available cables are those that belong to the same reference cable and pulling areas that you specify for the cable drum. This option is available only after you enter the required data and only if the current drum is not defined as spare.
Remove
Removes the selected cable from the current cable drum. This option is available only when cables are associated with the cable drum.
