Age of that cable put is before PCBs were banned for being carcinogenic.

Such cables no longer use oil. Cables for that voltage are even routinely buried in the ocean floor. One was discussed here long ago was from Connecticut to Long Island. It was incorrectly installed because it was not properly buried underneath the Sound.

Others carry power from off shore wind generators. The science has come a long way from those 'olden days'.
