LW3-10 Outdoor High Voltage SF6 Circuit Breaker
SF6 gas is poerbêst isolearjend en bôge-blussen medium, en it hat de bêste prestaasje. Sokke apparatuer is wrâldwiid de ûntwikkelingsrjochting.
LW3-10 I II type bûten SF6 circuit breakers oannimme SF6 gas as rec-blussen en isolearjend medium, dat wurdt tapast op sels-draaide bôge-blussen teory Bedriuwmeganisme is ferdield yn I type hân opladen spring operearjend meganisme, II type motor opladen spring bestjoeringsmeganisme en III type DC elektromagnetyske bestjoeringsmeganisme. Alle meganisme kin hiel goed gearwurkje mei brekker.
