GENUINE MICA high voltage insulating washers
Based on the “average puncturing voltage” table for the mineral mica, from the American Institute of Electrical Engineers website, each washer should withstand in excess of 8,000 volts! Of course, you can “stack” multiple washers for increased voltage ratings.
