Definitions
- the band 43 it is within the scope of this invention to apply other voltage breakdown enhancing materials as the band 43.
- the graphite might possibly be applied as a suspension that is painted on the end portion 40. In any event the effect of the graphite 43 is to permit a wider gap 42 for the same breakdown voltage than would be possible in the absence of the graphite.
