DLO/RHW Cable

[augie47]

I have an application where an E/C wishes to use DLO/RHW cable for a service lateral from a transformer vault.
He was trying to apply the 445 amp capacity listed on the product spec sheet for 535.5 kcmil cable, but that
is a 90? rating and his termination points are most likely 75?.
Since 535.5 is not a listed NEC size, how does one come up with an ampacity ?
