En tant qu'appareil \u00e9lectrique \u00e0 haute tension, le disjoncteur \u00e0 vide de type VZ4-12 convient au syst\u00e8me \u00e9lectrique AC 50Hz, tension nominale 12kV, utilis\u00e9 pour contr\u00f4ler et prot\u00e9ger la charge dans le circuit.<\/p>\n<p>\u3000\u3000<strong>Champ d'application et avantages<\/strong><\/p>\n<p>Ses principaux avantages sont sa petite taille, son poids l\u00e9ger, son fonctionnement pratique, sa grande fiabilit\u00e9 et sa facilit\u00e9 d'entretien. En outre, il pr\u00e9sente une bonne durabilit\u00e9 et de bonnes performances \u00e9lectriques, et peut r\u00e9sister \u00e0 des conditions anormales telles qu'une surintensit\u00e9 instantan\u00e9e et un courant de court-circuit afin de garantir le fonctionnement normal du syst\u00e8me \u00e9lectrique. En r\u00e9sum\u00e9, le disjoncteur \u00e0 vide VZ4-12 est un \u00e9quipement \u00e9lectrique efficace et fiable, largement utilis\u00e9 dans l'\u00e9nergie \u00e9lectrique, la m\u00e9tallurgie, la p\u00e9trochimie et d'autres domaines.<\/p>\n<p><strong>Principaux param\u00e8tres techniques des produits<\/strong><\/p>\n<table border=\"1\" cellpadding=\"0\" cellspacing=\"0\"
