Cables: Cable Library Twisted Cables

The dialog box is also available via Cable Navigation Tree: Library Cables. The icons on the top of the dialog box enable actions which are explained below. The meaning of each icon is also explained by tool-tips. To see a tool-tip just move the mouse-pointer over the corresponding icon:

  

 

All available Twisted cables are listed in the column on the left side of the dialog box. When selecting an item in the list the corresponding definition is shown on the right side. Each twisted cable requires a unique name that has to be assigned in the field Name. The underlying unit size for geometry definition can be selected with the Units pull-down menu. Changing the unit for an existing object does not affect the size of the cable but just displays the original size in the corresponding unit.

 

Twisted cables can be created for any kind of single wires regardless if they are of circular or any other shape. The corresponding geometrical and electrical parameters can be either entered directly (using the frames Conductor- and Insulator frames) or easily obtained by pressing the Single Wire button inside the Select in Library frame.  The number of single wires to be used for the  twisted cable can be specified inside the Number field. In case of two wires you define a so called twisted pair. The orientation of the twist can be specified with the pull-down menu next to Turn. The pull-down menu on the right hand side enables to specify how the length of a complete twist shall be defined. It can be set either as an absolute value (parameter Lay) or as a number of twists per meter.

 

The Preview button enables the display of the selected single wire in the Cross Section View window. The Undo button enables to undo any changes. When pressing the Apply button, however, all data will be updated in CST CABLE STUDIO and the Undo button will be automatically disabled then.
