A newly designed insulated constrictor nozzle, which was equipped the insulated constrictor section composed of the mutually insulated several water-cooled disks, was used to examine the constriction effect on the forced elongated arc. The arc voltage-current characteristics of the elongated arc was a rising characteristics. When the length of the insulated constrictor section was increased, the electric field intensity of the elongated arc was decreased at the outlet region of the insulated constrictor section and the heat loss of the insulated constrictor was increased with increasing distance from the insulated constrictor inlet. The thermal efficiency of the insulated constrictor section was 74 ~ 94% and was higher than that of the plasma jet generator.
