Installation buried underground

nonedirectly buriedThis analytic method is according to IEC 60287-2-1 with objects buried directly in homogenous and thermally stable soil. Cables can be laid inside ducts.
drywith drying-out of soilThis analytic method is an extension to the directly buried method with object buried directly in thermally unstable soil. Backfills cannot be added but cables can be laid inside ducts.
backwith backfill (for ductbank)This analytic method is an extension to the directly buried method. Up to five non-empty rectangular or round backfill areas can be defined. Objects may also be installed outside of the backfills and cables can be laid inside ducts.
femfinite element methodThis numeric method uses finite element to calculate the external thermal resistance of the ambient outside of cables and ducts. All losses are still calculated according to IEC standard.
subsubsea installationThis analytic method is in principle identical to the method with backfills according to IEC 60287-2-1 with. The preview is changed to represent objects buried in seabed underwater and some limitations apply.
The distinct subsea module offers more calculation methods in addition the IEC 60287 to allow for partially or non-buried cables but has other limitations in installation.
