Pipe-Only Cable

 Name for Identification

Text

Optional text parameter for identification of the component.

 Cable Number

Choice

Select a number between 1 to 12.  This parameter is used for the numbering of multiple cables in the same right of way.

Placement in Relation to Ground Plane

Choice

Choose whether this cable is placed above (Aerial) or below (Underground) the ground plane.

Depth Below Ground Surface

REAL

Literal

Enter the depth of the pipe centre-point below the earth surface [m]. The y-coordinate of all coax cables included in this pipe must be relative to this depth.

Loss Tangent is Defined At

REAL

Literal

Enter the frequency at which loss tangents are defined [Hz].

Horizontal Translation from Centre

REAL

Literal

Enter the translation of the pipe centre-point along the horizontal (x) axis [m]. This value is relative to a local x=0 point, which is derived given the position of all cables in this segment. The x-coordinate of all coax cables included in this pipe must be relative to this depth.

Layer Configuration

Choice

Select the configuration of the cable layers. C and I represent conducting and insulating layer respectively.

Layer Thickness is Specified As

Choice

Select the manner in which the layer thicknesses are specified. If radial from centre is selected, enter the distance from the centre-point to the outer radius of the layer.

Detailed Graphic Layers

Choice

Select show or hide.

Resistivity

REAL

Literal

Enter the resistivity of the corresponding conductor or insulator [Wm].

Relative Permeability

REAL

Literal

Enter the relative permeability of the corresponding insulator.

Inner Radius

REAL

Literal

Enter the inner radius of the corresponding conductor [m].

Outer Radius

REAL

Literal

Enter the outer radius of the corresponding conductor [m].

Resistivity

REAL

Literal

Enter the resistivity of the corresponding conductor or insulator [Wm].

Relative Permittivity

REAL

Literal

Enter the relative permittivity of the corresponding insulator.

Loss Tangent

REAL

Literal

Enter the loss tangent of the insulator.

Relative Permeability

REAL

Literal

Enter the relative permeability of the corresponding insulator.

Outer Radius

REAL

Literal

Enter the outer radius of the corresponding insulator [m].

Thickness

REAL

Literal

Enter the thickness of the corresponding insulator [m].

Resistivity

REAL

Literal

Enter the resistivity of the corresponding conductor [Wm].

Relative Permeability

REAL

Literal

Enter the relative permeability of the corresponding conductor.

 Inner Radius

REAL

Literal

Enter the inner radius of the corresponding conductor.  If this is the central solid conductor, enter 0.0 [m]

Outer Radius

REAL

Literal

Enter the outer radius of the corresponding conductor.

Thickness

REAL

Literal

Enter the thickness of the conducting layer [m]. Note that this parameter is enabled only if Layer thickness is specified as | actual thickness is selected.

Semi-Conducting Layers

Choice

Select whether or not there are semi-conducting layers present in this cable. Semi-conductor layers may only be included between the core and 1st conducting layers.

Relative Permittivity

REAL

Literal

Enter the relative permittivity of the corresponding insulator.

Relative Permeability

REAL

Literal

Enter the relative permeability of the corresponding insulator.

Outer Radius

REAL

Literal

Enter the outer radius of the corresponding insulator [m].

Thickness

REAL

Literal

Enter the thickness of the insulating layer [m]. Note that this parameter is enabled only if Layer thickness is specified as | actual thickness is selected.

Inner Semi-Conductor Layer Thickness

REAL

Literal

Enter the thickness of the inner semi-conducting layer (between insulator and core conductor) [m].

NOTE: This value should not be included as part of the conductor or insulator dimensions. The line constants program will take care of the semi-conductor layer automatically, given this thickness.

Outer Semi-Conductor Layer Thickness

REAL

Literal

Enter the thickness of the outer semi-conducting layer (between insulator and 1st conducting layer) [m].

NOTE: This value should not be included as part of the conductor or insulator dimensions. The line constants program will take care of the semi-conductor layer automatically, given this thickness.
