# Twisted Pair Cable

This option defines twisted pair cables with specified insulation, radius, twist pitch length and direction.

## Parameters:

Cross section label
The label of the cross section.
Core
PEC
Select this option to set the core of the cable to PEC.
Material label
The label of the metallic medium (as defined in the DI card) to be used for the core.
Core radius
The radius of the core.
Insulation
Material label
The label of the material (as defined in the DI card) to be used for the insulation layer.
Thickness
The thickness of the insulation layer (optional).
Twisted pair
Turn direction
Select left or right turn direction for the twisted pair.
Twist pitch length
The axial length in which a twisted pair strand returns to its original relative position in a twisted conductor.
Radius
The outer radius of the twisted pair cable.
Cable per-unit-length parameters accuracy
The Cable per-unit-length parameters accuracy can be increased from Normal (default) to High or Very high.
