Abstract
The arc withstanding electrodes in an electric circuit breaker for switching high voltages attain greater mechanical strength and improved arc withstanding capabilities by forming the arc withstanding electrodes of a carbon-fiber-reinforced-graphite material which material is constituted of a graphite matrix which is reinforced by carbon fibers embedded therein. A method for forming the carbon-fiber-reinforced-graphite of the arc electrodes and for affixing the arc electrodes to a metal carrier therefor includes the steps of employing a high-temperature solder based on copper and/or silver, containing at least one carbide-forming element such as, for example, Cr.
