* The Current was calculated based on TES-P-104.05 R0, Fig 05-03 but installed in ducts and the
following installation conditions:
1. Ground temperature = 40 deg. C.
2. Burial depth = 1.5 m.
3. Soil thermal resistivity = 2 k.m/w.
4. Backfill thermal resistivity = 1.2 k.m/w.
5. Duct Inner/Outer diameter = 154.1/168.3 mm.
6. The cable bonding type is cross bonding.
7. The Space between phases = 300 mm
** The Emergency Current was calculated based on the following:
1. before overloading the current was 873 A, based on the above mention installation conditions.
2. the overloading time assumed to be 1 hour.
3. the emergency temperature = 105 deg.C
