The sequel is never as good as the original except for The Godfather.

For some reason I can't download that information. I suspect it just means that the Southwire product is multiple-listed. Why spend the money to list three separate products if one product will meet all the requirements, especially if there is almost no cost delta in production?

Only that RHW-2 is 90*C in wet conditions versus its predecessor RHW which is 75*C rated.
Guess they didn't want to call it RHHW instead.

Does RHH have a 2 hour fire rating for fire pumps?

If I am reading this article correct: No.

Used to be apparently.

"Type RHH/RHW cable that was formerly listed for fire resistance is no longer fire resistance listed by UL."

Yes that article is almost 4 years old, I believe the UL has restored the use of RHH with a 2 hour rating.

I believe it's only 2 hour rated horizontal and not vertical(lost its listing)...need conduit to be run in vertical 2 hour rated enclosure( closet, shaft etc.)
