Hi All, hope your all well.
I was hoping if I can please get some advice in regards to SWA. In Particular using SWA as CPC. Cable size 95mm2
I have a table for SWA which shows various information, in the last two columns it shows the "resistance of steel armour under fault conditions at 70 degree" and "resistance of copper core at 20 degree"
it then shows different value of resistance from both columns as the cable of CSA changes. In the first table it stops at 35mm2 CSA. I have looked at other manufacture cable sizing and they give further cable sizing, it also gives me the "resistance of one copper core at 20 degree" for 95mm2 which is 0.193
Now my question
Is there a way to identify or to calculate what the "resistance of steel armour under fault conditions at 70 degree" would be for 95mm2?
Thank you
