Pagpahayag：
Ang ROCKWILL® nagtutuon sa kalidad sa produkto ug teknolohiya sa paggama, ug nagtrato sa bawg bahin sa produksyon sa produkto pinaagi sa eksakto ug maayo nga pinangandoy. Ang insulasyon gas lang ang gigamit aron mas makomparar ang pag-init sa dry air, nitrogen, carbon dioxide, ug pure air. Ang napiling insulasyon gas mao ang pure air na may kaayo ka gamay nga sulod sa tubig ug mataas nga purity tungod kay gipili kini isip substitute sa SF6. Ang core switch unit sa produkto nagamit og bag-ong vacuum arc extinguishing chamber soft package casting process, kasama ang mapanindot nga gi-disenyo nga rotating three-position switch, nga may simple ug kompakto nga overall structure; Ang fully sealed gas box nagsilbi isip substitute sa SF6 pinaagi sa pure air, nga may matangkad nga advantageous electric field distribution design, ug ang partial discharge sa buong cabinet adunay ubos 5pC; Ang salt spray resistance test sa operating mechanism sa zinc inlay alloy surface treatment process nakalampas sa 168 oras, ug ang pinakadako nga lifetime mahimong makaabot sa 30000 beses.
