LW3-10 Deyò High Voltage SF6 Awondisman brekè
SF6 gaz se ekselan mwayen izolasyon ak arc-extend, epi li gen pi bon pèfòmans. Ekipman sa yo se direksyon devlope atravè lemond.
LW3-10 I II III kalite deyò SF6 sikwi adopte SF6 gaz kòm rec-extend ak izolasyon mwayen, ki se aplike nan pwòp tèt ou-wotasyon arc extend teyori se mekanis opere divize an I kalite men chaje prentan mekanis opere, II kalite motè prentan chaje mekanis opere ak III kalite DC elektwomayetik mekanis opere. Tout mekanis ka kolabore ak kò brekè trè byen.
