Caract\u00e9ristiques de la structure du produit<\/strong><\/p>\n

Type KYN28-24 : appareillage de commutation CA blind\u00e9 amovible \u00e0 enveloppe m\u00e9tallique. Convient aux syst\u00e8mes \u00e9lectriques int\u00e9rieurs triphas\u00e9s 50\/60Hz, tension nominale 24kV. Principalement utilis\u00e9 dans les centrales \u00e9lectriques, les sous-stations, les entreprises industrielles et mini\u00e8res et les immeubles de grande hauteur, pour la r\u00e9ception et la distribution de l'\u00e9lectricit\u00e9, avec des fonctions de contr\u00f4le, de protection et de surveillance.<\/p>\n

Les parties amovibles de l'appareillage de connexion peuvent \u00eatre \u00e9quip\u00e9es de chariots de disjoncteurs \u00e0 vide, de transformateurs de tension, de parafoudres, d'isolateurs, de fusibles, etc.<\/p>\n
