A cable bundle may consist of multiple defined cables (for example, single
conductors, coaxial cables, ribbon cables, twisted pairs, other cable bundles and
non-conducting elements) that are embedded in a medium with an optional shield.
Note: The following shield types are supported for cable bundles:
Insulated, embedded in background medium
(sheath/jacket)
Not shielded, embedded in a dielectric
Not shielded, embedded in background medium
Shielded, dielectric filled
On the Cables tab, in the
Definitions group, click the Cable bundle icon.
On the Bundle tab, bundle the cables using one of the
following methods:
To create a cable bundle where the exact orientation of the cable in the
bundle is unknown or not relevant, select the Auto
bundle check box.
Click the Rearrange button to place the
cables in a new random location inside the bundle.
To specify the location and orientation of the cables inside the cable
bundle, clear the Auto bundle check box.
Specify the Offset X, Offset
Y and Rotation of each cable
contained in the bundle.
From the Cabledrop-down list, specify the cables contained in the bundle using
one of the following methods:
To specify a predefined cable, select the cable you want to
add.
To specify a cable, not yet defined in the model, click the icon to define a cable type.
On the Insulation and Shielding tab, for shield types
1, 2 and 4, specify the
Insulation medium.
On the Insulation and shielding tab, from the
Insulation mediumdrop-down list, select one of the following:
To specify the insulation medium consisting of a predefined dielectric,
select the dielectric.
To specify the insulation medium consisting of dielectric, which is not
yet defined in the model, click the icon to define a dielectric or add a dielectric
from the media library.
For shield types 1, 2
and 4, specify the
Outer radius for the cable bundle.
On the Insulation and shielding tab, to specify the
Outer radius, select one of the following:
To allow CADFEKO to calculate the outer radius
of the cable bundle, select the Compute automatically
check box.
To manually specify the outer radius of the cable bundle in the
Outer radius field, clear the Compute
automatically check box.
For shield type 1, specify the Shield for the cable bundle.
Note: If a
braided shield is applied to the cable bundle the outer radius should be between
the stretching limits defined for the braided shield.
On the Insulation and shielding tab, under
Shielding, from the Shielddrop-down list, select one of the following:
To add an outer cable shield consisting of a predefined shield, select a
cable shield.
To add an outer cable shield consisting of a shield, which is not yet
defined in the model, click the icon to define a new cable shield.
Under Insulation layer (coating), specify the
following:
To add a coating, select the Apply
coating check box.
From the Mediumdrop-down list, specify the coating medium.
In the Thickness field, specify the coating
thickness.
To remove the coating, clear the Apply coating
check box.
On the Advanced tab, under Twist,
from the Twist directiondrop-down list select one of the following:
To define a bundle with no twist, select No
twist.
To define a bundle turning right, leading away from you, select
Right handed.
To define a bundle turning left, leading away from you, select
Left handed.
On the Advanced tab, under Twist,
in the Twist pitch length field, enter the axial length
required to complete one revolution of a cable in the bundle around the diameter
of the bundle.
In the Label field, add a unique label for the cable
bundle.
Click Create to create the cable bundle and to
close the dialog.
