A new approach for modeling pipe-type cables with both metallic and non-metallic enclosures is
developed in TRALIN. This development represents a significant generalization of the cable
model previously used in SES Software, which was limited to configurations where the enclosing
pipe was metallic. The new approach extends the modeling capabilities to accommodate a broader
range of practical cable designs, enhancing the accuracy and flexibility of electromagnetic
simulations in complex environments.
To accommodate the new non-metallic enclosure capability in SESTralin, the pipe enclosure can
now be defined as either a conductive or a non-conductive material. This option is shown in the
following picture, where the Type field includes a dropdown menu. Selecting Non-Conductive
enables the relative permittivity and disables the With Coating option, since insulating
enclosures are not coated.
