Definition

Cable segments represent sections into which the cable is fictively subdivided. A cable always consists of at least one cable segment.

When creating a new cable, a cable segment is automatically created, which is identical to the cable.  The cable may be subdivided by the user into further cable segments, where the following applies:

•A cable segment lies between 2 locations A and B

•A cable segment may start and end in a shaft/container.

•A cable segment may lie between A and B in an Duct,

resulting in the following characteristics per segment:

Length[m]

Number

Sum. length[m]

Number

Name

The name of the segment is created automatically from “Cable name_Segment no”. It can be changed at any time.

 

Location A, Location B

Are the two locations between which the cable segment is positioned.
The locations must be indicated.

The A location of the first segment is the same as the A location of the cable.

The B location of the last segment is the same as the Z location of the cable.

 

Shaft/Cable A, Shaft/Container B

Are the two components of the category “Container/Cabinet” or “Shaft” between which the cable segment may lie; however, they must not be allocated.

The definition is the same as the end components of the cable themselves.

The Shaft/Container A of the first segment is the same as the A component of the cable.

The Shaft/Container B of the last segment is the same as the Z component of the cable.

 

Duct

Is a component of the category “Duct” in which the cable segment between Location A and Location B may lie.

 

Length

The length describes the cable length between locations.

This may be calculated based on the recorded parameterisation values.

Amount(Parameterisation A – Parameterisation B)

 

Excess length A, B

Excess lengths describe the cable lengths lying in Location A and/or Location B.  The following applies to excess lengths:

•The first cable segment may have excess lengths in Location A and Location B.

•Every additional cable segment may only have excess lengths in Location B.

 

Cum. length[m]

Cumulated length is automatically calculated from the sum of all lengths and excess lengths.

 

Effective length, geographic length

For the cable itself, the following characteristics are automatically derived according to the definition of the cable segments with lengths and excess lengths:

•Geographic length: corresponds to the cable length directly set between A and Z. It is automatically calculated from:

Geographic length = S Segment lengths

•Effective length: corresponds to the total length of the cable segments lying between A and Z. It is automatically calculated from:

Effective Length = S Segment lengths + S Excess lengths
