Abstract
A ceramic insulator body for receiving and electrically isolating two parallel terminal rods is manufactured by radial isostatic compaction of a ceramic powder about a core member having an hourglass cross section. The core member produces a bore comprising two parallel terminal-receiving channels connected by a constricted passage that is sized and shaped to space apart two terminal rods in the channels.
