No. Bethesda placed by mistake the simulation version of the Winterized T51-b armor set, which has 10 million health, instead of the Wasteland version. The simulation version cannot be repaired other than by merchants. The actual Wasteland that was not placed in the game can be repaired with the T-45d Power Armors.
This problem has been however fixed by the Unofficial Fallout 3 Patch.
