Descripio：
ROCKWILL® magnam pondus adhibet qualitati producti et technologiae manufacturae, singulosque gradus productionis producti cum exactitudine et diligentia tractat. Solum gas insulans ad comparationem completa caloris sicci aeris, nitrogenii, carbonis dioxidici, et puri aeris utitur. Purus aer compositus cum contentu humiditatis extrema minimo et puritate maxima pro electo gas insulante substituto SF6. Nucleus unitatis commutatoriae producti novam processum fundendi vacui camarae extinguendi arcus in moli molliter castigata adhibet, coniunctus cum interruptore triplici positione curate designato, structura tota simplex et compacta; Cista gasea perfecte clausa SF6 purum aerem substituit, cum designamento distributionis electrici campi valde ad vantage, et emissio partialis totius cistae infra 5pC est; Testum resistendi salinis nubibus mechanismo operativo processu superficiei alligatae zinco excedit 168 horas, et longissima vita utilitatis potest ad 30000 vice attingere.
