IMPROVED CLOSING-RESISTOR SUPPORT FOR EHV POWER CIRCUIT-BREAKERS ABSTRACT OF THE DISCLOSURE An improved closing resistor support is provided for the closing resistances of high-voltage high-power com- pressed-gas circuit-interrupters in which the formerly-used insulating straps are completely eliminated, and consequently the voltage conditions are thereby improved to thus withstand a much higher-voltage breakdown capability during the closing operation. A metallic ring is preferably utilized at the front end of the circular closing resistance assemblage and provides a uniform compression of the individual resistor coils and, additionally, provides a desirable electrical field condition at the resistor assemblage.
