-Cable
current carrying capacities and cable cross-section selection
are made according to
IEC 60502-I
Direct in Ground (30 deg. C), Direct in Duct (30 deg. C).Thermal
resistivity of soil=150 deg. C cm/W
**Aluminum grounding conductor can be laid inside the building.
It cannot be laid in the ground.
**In our facilities, instead of copper material in column cables
and grounding conductors, Aluminum can be used as column cable
and braided steel wire can be used as grounding conductor. |
|
*** The cross-section of the neutral conductor at a distance of
20 m from the protective grounding has been calculated. |
|
****In
our facilities, the cross-section of the protection grounding
may be equal to or larger than the neutral grounding conductor
cross-section. Click for detailed calculations. |
