Beskrywing：
ROCKWILL® het groot waarde aan produk gehalte en vervaardigingstegnologie, en behandel elke stap van produksie met presisie en grondigheid. Slegs isolerende gas word gebruik om warme droë lug, stikstof, koolstofdioksied, en suiwer lug te vergelyk. Lug met uiteraard lae waterinhoud en hoë puurheid is gekies as die voorkeurlike isolerende gas om SF6 te vervang. Die kern skakel eenheid van die produk maak gebruik van 'n heel nuwe vakuum boogverdeling kamer sagte pakking gietproses, gekombineer met 'n sorgvuldig ontwerp roterende drie-posisie skakelaar, met 'n eenvoudige en kompak struktuur; Die volledig geslote gas boks vervang SF6 met suiwer lug, met 'n hoog voordelige elektriese veld verspreiding ontwerp, en die deelse ontlading van die hele kabinet is onder 5pC; Die sout spui weerstandstoets van die bedieningsmekanisme van die sink inlegsel oppervlak behandelingsproses het meer as 168 ure oorskry, en die langste leeftyd kan 30000 keer bereik.
