Modèle: Electric Control System
marque: HTD
Lieu d'origine: CHINE
Positionnement du produit :
La barre omnibus de l'unité de distribution haute tension HTD est le composant conducteur central intégré à l'intérieur de l'unité de distribution d'énergie (PDU/BDU) responsable de la distribution, de la conversion et de la protection de l'énergie électrique. Agissant comme « squelette » et « vaisseaux sanguins » du système de distribution d’énergie, il collecte le courant élevé à partir du circuit principal et, grâce à sa conception multibranches intégrée, distribue l’énergie de manière précise et fiable aux différents sous-circuits. Utilisant des alliages de cuivre/aluminium hautement conducteurs et une technologie de moulage par insert, il atteint l'équilibre parfait entre faible impédance, capacité de transport de courant élevée, sortie multicanal et indice d'isolation élevé dans un espace limité, ce qui en fait un élément clé pour améliorer la densité de puissance, la sécurité et la fiabilité globales du système.
