Beskrywing：
ROCKWILL het groot waarde aan produk gehalte en vervaardigingstegnologie, en behandel elke stap van produksie met presisie en sorgvuldigheid. Slegs isolerende gas word gebruik om warme droë lug, stikstof, koolstofdioxide en suiwer lug te vergelyk. Lug wat gesinteseer is met uitermate lae waterinhoud en hoë puurheid is gekies as die voorkeurlike isolasiegas om SF6 te vervang. Die kernskakel eenheid van die produk maak gebruik van 'n volledig nuwe vakuum boogblusser kamers sag pakking proses, gekombineer met 'n deurgaans ontwerp rotasie drie-posisie skakelaar, met 'n eenvoudige en kompak struktuur; Die volledig geslote gas doos vervang SF6 met suiwer lug, met 'n hoog voordelige elektriese veld verspreiding ontwerp, en die gedeeltelike ontlading van die hele kabinet is onder 5pC; Die sout spuit weerstand toets van die bedieningsmekanisme van die sink inleiding legering oppervlak behandelingsproses het meer as 168 ure oorskry, en die langste lewensduur kan 30000 keer bereik.
