From the conceptual point of view any transmission line has four parameters per meter. It has an inductance L .of its conductors , a resistance R of its conductors, a capacitance C between its conductors and a leakage conductance G between its conductors. The value of these parameters depends on the construction of the the transmission line; the cross section of its conductors, the material of its conductors, the distance between its conductors and the insulator between its conductors. The transmission line used to transmit electric power works at much higher voltage than the the distribution wire. There fore the distance between the wires is made much larger than the distribution line which leads to much higher magnetic energy storage and consequently its inductance per unit length will be higher.
Concerning the resistance which depends on the cross section and material type it will be comparable for the same carrying capability because the cross section's sized to limit the ohmic losses.
Accordingly the L/R ratio of the transmission line will be higher than that of the distribution line for the same current ratings.
