The run from the power company wiring...down to the meter is the owner's

You should look around more. I can show you thousands of houses with
cable. When I lived in Philadelphia, I never saw a conduit entrance
unless it was from an underground entrance, a rarity. .


I'd replace it and not try to somehow re-insulate.

I'd inspect if first, then decide what to do.
