Nos avantages<\/h2>\n

Conception de la bobine en spirale :<\/h3>\n

Nos bobines sont con\u00e7ues avec des conduits d'huile longitudinaux qui assurent une tr\u00e8s bonne dissipation de la chaleur, de faibles fuites magn\u00e9tiques et une grande r\u00e9sistance m\u00e9canique. Cela am\u00e9liore consid\u00e9rablement la capacit\u00e9 de r\u00e9sistance du transformateur aux courts-circuits.<\/p>\n

Noyau \u00e0 haut rendement :<\/h3>\n

Le noyau de fer utilise des t\u00f4les d'acier au silicium empil\u00e9es (moins de 0,35 mm d'\u00e9paisseur) ayant une conductivit\u00e9 magn\u00e9tique \u00e9lev\u00e9e. Cela r\u00e9duit les pertes \u00e0 vide et le courant, am\u00e9liorant ainsi l'efficacit\u00e9.<\/p>\n

Isolation de haute qualit\u00e9 :<\/h3>\n

Nous utilisons des mat\u00e9riaux isolants r\u00e9sistants \u00e0 la chaleur qui peuvent supporter des surtensions et des surintensit\u00e9s pendant le fonctionnement, ce qui garantit des performances durables et s\u00fbres.<\/p>\n

Huile pour transformateurs :<\/h3>\n

Notre huile a une faible viscosit\u00e9, un excellent transfert de chaleur et des propri\u00e9t\u00e9s d'isolation sup\u00e9rieures, prot\u00e9geant le noyau et les enroulements, ralentissant le vieillissement de l'isolation et prolongeant la dur\u00e9e de vie du transformateur.<\/p>\n

R\u00e9servoir d'huile ondul\u00e9 :<\/h3>\n

Fabriqu\u00e9s \u00e0 partir d'acier sup\u00e9rieur lamin\u00e9 \u00e0 froid, nos r\u00e9servoirs ondul\u00e9s sont trait\u00e9s pour durer et recouverts d'une peinture \u00e0 trois \u00e9preuves - r\u00e9sistance \u00e0 la pluie, \u00e0 l'humidit\u00e9 et au brouillard salin - qui accro\u00eet la fiabilit\u00e9 et r\u00e9duit les co\u00fbts d'entretien.<\/p>\n

Des joints fiables :<\/h3>\n

Nous utilisons des joints en caoutchouc de haute qualit\u00e9 pour pr\u00e9venir efficacement les fuites d'huile et emp\u00eacher l'air ext\u00e9rieur de p\u00e9n\u00e9trer, ce qui ralentit le processus de vieillissement et garantit les performances du transformateur.<\/p>\n

Applications des enroulements de transformateurs<\/h2>\n

R\u00e9glage de la tension ou du courant : Les transformateurs peuvent augmenter ou diminuer la tension ou le courant dans un circuit \u00e0 courant alternatif.<\/p>\n

Contr\u00f4le de l'imp\u00e9dance : Permet de r\u00e9gler les valeurs des condensateurs, des inductances ou des r\u00e9sistances dans un circuit \u00e0 courant alternatif.
\nIsolation DC : La tension continue ne peut pas passer d'un circuit \u00e0 l'autre par l'interm\u00e9diaire d'un transformateur.
\nIsolation \u00e9lectrique : Il s\u00e9pare \u00e9lectriquement deux circuits, garantissant ainsi la s\u00e9curit\u00e9 lors de leur utilisation.
