The ARRL Handbook and various QST, HRM articles lists them at 2000-2500V
safe maximum which closely coincides to the ratings of standard cable.

You are way off Ian. RG-58C/U is rated at 1900V and RG-59B/U is rated at
2300V per MIL -HDBK-216. Those are the solid dielectric cables, not foam.

70 or 80C depending if it is commercial or Mil rated for RG-58, only 60C
for RG-213 per Belden catalog.
