A good quality voltage regulator??

The use of treated paper was common as an electrical insulator. The pole coils can have magnetic attraction and could draw small ferrous particles so the cover cap and paper insulation helps to prevent that.

The old Model A power house generators had a lot of paper in them due to the number of coils in the field.
