III. Champ d'application<\/strong><\/strong><\/h2>\n\n\n\n

Cette bo\u00eete de contact \u00e0 double passage convient aux \u00e9quipements de distribution d'\u00e9nergie haute tension tels que les appareillages de commutation \u00e0 chariot et les appareillages de commutation moyenne tension de niveau 35KV-40.5KV. On la trouve couramment dans les installations \u00e9lectriques telles que les sous-stations industrielles, les salles de distribution d'\u00e9nergie des grands immeubles de grande hauteur et les centres de d\u00e9p\u00eache d'\u00e9nergie. En tant que composant de transition isolant pour la connexion bidirectionnelle des circuits haute tension, elle assure une connexion fiable et une isolation entre deux circuits \u00e9lectriques.<\/p>\n\n\n\n

IV. Conditions d'utilisation<\/strong><\/strong><\/h2>\n\n\n\n

L'altitude \u00e0 laquelle l'installation est effectu\u00e9e ne doit pas d\u00e9passer 1000 m\u00e8tres.<\/p>\n\n\n\n

2. La temp\u00e9rature de l'air ambiant est de -40\u2103 \u00e0 +70\u2103, et l'humidit\u00e9 relative ne d\u00e9passe pas 95% (\u00e0 25\u2103) ;<\/p>\n\n\n\n

3. Le site d'installation doit \u00eatre exempt de gaz, vapeurs, poussi\u00e8res et autres milieux explosifs et corrosifs susceptibles d'affecter s\u00e9rieusement les performances d'isolation de la bo\u00eete de contact ;<\/p>\n\n\n\n

4. Il doit \u00eatre install\u00e9 dans un endroit exempt de vibrations et de chocs importants afin d'assurer la stabilit\u00e9 structurelle du produit.<\/p>\n\n\n\n

V. Caract\u00e9ristiques du produit<\/strong><\/strong><\/h2>\n\n\n\n

1.<\/strong> Excellente performance d'isolation<\/strong> Il est moul\u00e9 par le proc\u00e9d\u00e9 APG \u00e0 la r\u00e9sine \u00e9poxy, qui offre de bonnes performances d'isolation et d'\u00e9tanch\u00e9it\u00e9, isole efficacement les circuits haute tension, emp\u00eache la poussi\u00e8re et l'humidit\u00e9 ext\u00e9rieures de p\u00e9n\u00e9trer et garantit la fiabilit\u00e9 des connexions \u00e9lectriques.<\/p>\n\n\n\n

2.<\/strong> Conductivit\u00e9 fiable<\/strong> Les bornes sont en alliage de cuivre \u00e9tam\u00e9\/argent\u00e9, tandis que les contacts sont en acier inoxydable ou en cuivre, qui pr\u00e9sentent une excellente conductivit\u00e9, r\u00e9sistance \u00e0 la corrosion et \u00e0 l'usure, garantissant une transmission stable du signal \u00e9lectrique.<\/p>\n\n\n\n

3.<\/strong> Structure stable et durable<\/strong> La structure moul\u00e9e monobloc pr\u00e9sente une r\u00e9sistance m\u00e9canique \u00e9lev\u00e9e, peut supporter les contraintes m\u00e9caniques et \u00e9lectriques \u00e0 l'int\u00e9rieur de l'armoire de commutation, s'adapter aux conditions de fonctionnement complexes des syst\u00e8mes de distribution d'\u00e9nergie haute tension et a une longue dur\u00e9e de vie.<\/p>\n\n\n\n

4.<\/strong> Installation facile<\/strong> Les dimensions d'installation standardis\u00e9es s'adaptent aux exigences d'installation des appareillages de commutation haute tension conventionnels, facilitant l'installation et le remplacement sur site.<\/p>\n\n\n\n

5.<\/strong> Forte adaptabilit\u00e9 environnementale<\/strong> Con\u00e7u pour une large plage de temp\u00e9ratures, il peut s'adapter aux environnements extr\u00eames de froid intense et de haute temp\u00e9rature. Avec un indice de protection IP67, il offre de bonnes performances d'\u00e9tanch\u00e9it\u00e9 \u00e0 la poussi\u00e8re et \u00e0 l'eau.<\/p>\n\n\n\n
