Paglakip:
Ang ROCKWILL nagkonsidera sa kalidad sa produkto ug teknolohiya sa pagbuhat, ug gihatagan kini og presisyon ug detalye sa bawg proseso. Ang langit nga gas ang gigamit sa komparasyon sa pagsul-ob sa dry air, nitrogen, carbon dioxide, ug pure air. Ang pure air nga may kaayo ka gamay nga kontenido sa moisture ug mataas nga purity ang gipili isip pipila nga insulation gas aron mapalit ang SF6. Ang core switch unit sa produkto adunay bag-ong vacuum arc extinguishing chamber soft package casting process, na gikombinado sa maayo nga gidisenyo nga rotating three-position switch, ug simple ug compact nga overall structure; ang fully sealed gas box napalitan ang SF6 ngadto sa pure air, ug may makapadali nga electric field distribution design, ug ang partial discharge sa tanang cabinet mahimong mas mababa sa 5pC; ang salt spray resistance test sa operating mechanism sa zinc inlay alloy surface treatment process gibaha sa 168 oras, ug ang pinaka dako nga serbisyo mahimong 30000 beses.
