Calculating cross-section with known cable lengths [t-head3]
The minimum cross-section is determined for the known maximum expansion of the network.
| l |
= |
Length of conductor in m |
| Smin |
= |
minimum cross-section in mm2 |
| ρcu |
= |
specific resistance of copper, unless otherwise stated 0.018 Ωmm2/m |
Note
If the result of the calculation is not a standard cross-section, use the next highest standard cross-section.
Calculating length with known cable cross-section [t-head3-col]
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 state 0.018 Ωmm2/m |
