A solid-insulated, infinitely long tubular copper conductor is enclosed by a housing. In the gap between the solid insulation and the housing, oil functions as an insulating gas

In the thermal network, the processes of conduction, radiation and convection are emulated dependently on the geometry of the arrangement, the time-dependent environmental conditions and the load current that the arrangement is exposed to. While doing so, the thermal capacity of the arrangement is taken into account.

The temperature calculations are carried out dynamically and dependently on time.
