I have some inductance data on 22 gauge high capacity twisted pair tel=
ephone
cable.
parameters are Hz, ohm/mile, mH/mile, umho/mile, uF/mile

f R L G C
0 166.8 .802 --- .0825
1K 166.9 .798 1.2 .0820
10K 168.6 .792 30.2 .0817
100K 209 .773 603 .0810
1M 545 .654 8900 .0808
10M 1725 .593 78400 .0808

The inductance in this data is at least qualitatively
similar to your data.

I believe this data was determined by measuring characteristic
impedence, propagation attenuation, and propagation velocity
and then calculating R,L,G,C to match the data.
