Cable inductance and capacitance values per km

Cable inductance and capacitance values per km

Cable inductance and capacitance values per km

(OP)
Hello,
I have a data sheet for RFOU (I) cable,
The capacitance, inductance values are only given for one pair and one triple for three different sizes( 0.75,1&1.5mm2)My question is are these values also the same if you are using a multi pair of the same cable eg 4,8,12 pairs as this information is not on the data sheet.

Thanks

RE: Cable inductance and capacitance values per km

There are not multiple conductor cables but multiple elements cable. One element contains 2 ,3 or 4 conductors twisted and shielded. The screen decreases the external capacity and the twist decreases the influence of the external magnetic fields.

Thanks for this. So this capacitance and inductance data can be used for multi pair cables as each pair has 2 “elements”.

Thanks
