Code question

I’m currently doing my advanced level schooling and I got a code hw question that says “…a 480-240 XFMR has 90°c rated termination, the primary side is fed with RW90XLPE (unjacketed) and the secondary is fed with tw75…”.
If terminations are rated for 90° how can you use a 75 degree insulated conductor?

EDIT: this is based off the CEC
