Opis：
ROCKWILL pripisuje veliko pomen produkti kakovosti in proizvodnemu tehnologiju, ter vsak korak proizvodnje ravna natančno in skrbno. Za celovito primerjavo se uporablja samo izolacijsko plin, vključno z segrevanjem suhega zraka, dušika, ogljičnega dioksida in čistega zraka. Izbran je bil sintetični čisti zrak z zelo nizko vlažnostjo in visoko čistočo kot prvoizbirska izolacijska plin za nadomestitev SF6. Jezgra stikala produkta uporablja popolnoma nov postopek mehkega oblitja vakuumne ugasevalne komore, kombiniran s starostno razvitim vrtilnim trehpoloznim stikalom, z enostavno in kompaktno celotno strukturo; V celotno zaprti plinski škatli se SF6 nadomesti z čistem zrakom, z zelo ugodno razporeditvijo električnega polja, pri čemer je delna razsevanje celega škrinja pod 5pC; Solani preskus operacijskega mehanizma z postopkom površinske obravnave zinkastega zliva presegel 168 ur, najdaljša življenjska doba pa lahko doseže 30000 ponovitev.
