| Calculation of cross section when conductor length is known |
The minimum cross section is calculated for the know maximum use of the network.
l = Length of conductor in m
Smin = minimum cross section in mm2
ρcu = specific resistance of copper, when nothing else given 0,018 Ωmm˛/m
Note :
When the result of the calculation doesn´t give a normal cross section use the next highest normal cross section. |
| Calculation of conductor length when the cross section is known |
For a known conductor cross section the maximum conductor length is calculated.
lmax = Length of conductor in m
S = Conductor cross section in mm2
ρcu = specific resistance of copper, when nothing else given 0,018
Ωmm˛/m
