Although the dielectric is mostly air, the  electric
field is not uniform, and is actually much higher
near the  wire, right where the dielectric is.
The effect is greater than you might  think.  My
450 ohm line is made of AWG 4 stranded aluminum
with  THHN insulation.  I had to increase the spacing by
about 10% to  account for the dielectric.
