I actually saw a lead jacketed, gutta percha wrapped line explode in
Florida back in the '70's.
As the lines were replaced we salvaged a lot of the lead for cryostat
air-leg masses.

In all fairness, underground power has had serious problems with
ground water leakage up until the late '90's or so when PVC conduit
began being used.
Well, I wondered about that at the time (circa 1980), but there has
never been a problem despite lots of freezing and thawing of our
ground, really wet times, etc.
