It varies somewhat. Here in Arizona we draw the line (he
he) between 69 KV for low tension and 230 KV for high
tension. We have very little in the 115 KV range. In
neighboring states, especially California, they have a much
greater range and draw the line differently. Close enough
for general use: HT is above 100 KV; LT is below 100 KV.
There is also a rating for EHV (extremely high voltage)
subs; for us it is 345 and 500 KV but not 230. I'm guessing
OSHA has the last word :)
