Origin: CHINE
Lieu d'origine: CHINE
Positionnement du produit :
La barre omnibus principale en aluminium CC du conteneur HTD ESS sert d'épine dorsale d'alimentation à haut rendement pour les systèmes de stockage d'énergie à l'échelle des services publics. Conçu à partir d'un alliage d'aluminium de série 6 à haute conductivité (conductivité ≥ 55 % IACS), il garantit une transmission fiable de courant élevé (1 000 A à 12 000 A) entre les groupes de batteries et le PCS. Sa conception tubulaire creuse innovante maximise la dissipation thermique, limitant l'augmentation de la température à ≤40K au courant nominal. Avec une faible impédance nominale de ≤0,035 Ω·mm²/m et un encombrement compact représentant un tiers de la taille des câbles traditionnels, ce jeu de barres améliore la densité de puissance du système tout en garantissant une distribution et une convergence CC robustes.
