Opis：
ROCKWILL® pripisuje veliko pomen produkti in proizvodnji ter vsak korak proizvodnje obravnava natančno in skrbno. Za celovito primerjavo se uporablja le izolacijski plin, zato se uporabljajo zagrevan zrak, dušik, ogljikov dioksid in čist zrak. Izbran je bil sintetični čist zrak z zelo nizko vsebnostjo vlage in visoko čistočo kot priljubljen izolacijski plin za nadomestitev SF6. Jezgre električnih ventilov izdelka uporabljajo popolnoma nov postopek mehkega litja vakuumskih zganevalnikov, kombiniran s skrbno oblikovanim vrtečim se trehpolnim preklopnikom, kar omogoča preprosto in kompaktno celotno strukturo; V celotno zaprta plinska škatla nadomešča SF6 z čistim zrakom, z zelo ugodno razporeditvijo električnega polja, pri čemer je lokalna razsevanost celega kabinetnega sistema pod 5pC; Test odpornosti na solano mlazo mehanizmov z površinsko obdelavo z injekcijo cinka presegel 168 ur, najdaljša življenjska doba pa doseže 30000 ponovitev.
