Allows you to define and edit basic properties of a cableway segment used to route cables.
Item tag
Allows you to specify a tag that uniquely identifies the cableway segment.
Cableway
Displays the cableway with which the segment is associated. This value is read-only.
Description
Allows you to type a description of the cableway segment, for information only.
Item status
Allows you to select an appropriate status of the equipment indicating whether the item is active or deleted.
Category
Displays the category of the cableway component used as the reference item for the cableway segment. If no reference cableway component is selected, you can also select a category: Tray, Conduit, or Miscellaneous, which the software uses to filter the results when you select Find to look for a reference cableway component to associate.
Segregation level
Allows you to specify a segregation level for the segment. All segments that belong to a particular routing path must have the same segregation level, and all cables that you route through those segments must have the same segregation level as those segments.
Reference component
Describes the reference cableway component used as the catalog item for the segment. Default values for some of the segment properties, such as Length, Width, and some fill properties come from the component.
Find
Opens the Find dialog, where you can select a reference cableway component to which you assign the current cableway segment.
Dissociate
Allows you to clear the association of the selected reference component with the cableway segment.
Length
Allows you to type a value for the length of the segment. You can use the value that you type to represent a space reservation or an actual length of routing.
Diameter
Displays the value of the diameter of the cableway segment. This read-only value comes from the reference cableway component used as the basis for this segment and applies only to segments with category Conduit.
Width
Displays the value of the width of the cableway segment. This read-only value comes from the reference cableway component used as the basis for this segment and applies only to segments with category Tray or Miscellaneous.
Depth
Displays the value of the depth of the cableway segment. This read-only value comes from the reference cableway component used as the basis for this segment and applies only to segments with category Tray or Miscellaneous.
Notes
Allows you to enter text, for example, if you want to provide additional information about the segment.
Adjacent segments
Displays the names of the segments on either side of the current segment in the cableway. The positions of the segments are determined by the sequence assigned to them on the Cableway Common Properties dialog.
From segment
The segment with sequence number preceding that of the current segment. If no segment precedes the current segment, the software displays End.
To segment
The segment with sequence number following that of the current segment. If no segment follows the current segment, the software displays End.
Segment fill
The software calculates on the fly the segment fill percentage for the cables. These cables are routed on the segment as part of the routing, validating the segment fill percent values against the maximum allowed values that you specify or, as defined by NEC code. The software takes into account the fill factor that you specify and the maximum weight per unit length allowed on the tray. If any of the actual values exceed the allowed values, the software rejects them and displays a warning message. For area or width calculations, the software performs the validation according to the segment category and whether or not the segment is covered. The dynamic text that appears indicates the validation method that the software uses. Note that cable fill validation depends on the values that exist in the Conductor Area cmils lookup table. If the value that you require is not in this lookup table, add it manually before calculating the segment fill percentage.
Allow overfill
Select this check box to ignore validation of values that exceed the allowed area or weight.
Covered
Displays whether the current cableway segment is covered or not. You cannot change this setting because this parameter is inherited from the associated cableway component tray in the Reference Data Explorer.
Calculation criteria
Select the required tray fill calculation (shown in percent) by Area or Width or Auto. Select Auto if you require the calculation by the Covered flag (default). Note that when using NEC validation method, the Calculation criteria list is disabled.
Maximum area
The maximum available area for the segment. For a covered segment, the software calculates the area by multiplying the width and depth values together. For a conduit, the software calculates the area from the diameter. This value is read-only, and comes from the reference cableway component. Note that when using the NEC Validation method, the Maximum area, Allowed area, Accumulated area and Accumulated diameter values are calculated in inches.
Allowed area
The actual maximum area of the segment that cables included in the routing are allowed to occupy. The software calculates this value as the product of the maximum area and the fill factor. Note that when using the NEC validation method, the Allowed area value is derived from NEC tables according to the cable type of the cables, located in the tray. Note that when using NEC validation method, for conduits, the Allowed area value changes according to the number of cables in the conduit. Note that this pane will be activated only if the calculation is by Area.
Allowed width
The actual maximum width of the segment that cables included in the routing are allowed to occupy. The software calculates this value as the product of the Maximum width of the tray, the layers and the Fill factor, Using NEC validation method the software derives the Allowed width from the NEC tables. Note that this pane will be activated only if the calculation is by width.
Fill factor
Type a value representing the fraction of the maximum area or the maximum width that you want to allow when adding cables to the segment. You can type any positive value, including values that are greater than 1; however, for conduits, covered trays or for NEC, the fill factor value should not exceed 1.
De-rating factor
Used for NEC validation, This code factor can have one of three different values (0.4, 0.5, 0.9), The code multiplies the Allowable width or the Allowable area.
Accumulated area
The total area occupied by the cables routed through the current segment. When appropriate, the software validates this value against the allowed area value. Note that when using the NEC validation method, the Accumulated area value may be higher than the Allowed area value.
Number of layers
Type an integer indicating the number of layers of cables that you want to allow when the software performs validation by diameter.
Accumulated diameter
The sum of the outer diameters of all the cables routed through the current segment. When appropriate, the software validates this value against the product of the segment width, the fill factor, and the number of layers.
Single-core cable fill %
Calculates the segment fill percentage assuming that only single-core cables are routed through the current segment.
Multi--core cable fill %
Calculates the segment fill percentage assuming that only multi-core cables are routed through the current segment.
Total fill %
Calculates the total combined segment fill percentage for single-core and multi-core cables that are routed through the current segment.
Maximum weight
The maximum weight per unit length of cables that the segment is capable of supporting. This value is read-only and comes from the reference cableway component.
Allowed weight
The actual maximum weight per unit length that cables included in the routing are allowed to reach. The software calculates this value as the product of the maximum weight and the weight factor.
Weight factor
Type a value representing the fraction of the maximum weight per unit length that you want to allow when adding cables to the segment. You can type any positive value, including values that are greater than 1.
Accumulated weight
The total weight per unit length of the cables routed through the current segment.
