Barra di distribuzione della batteria in rame per veicoli a nuova energia
√ Facile da installare e integrare nei sistemi di batterie
√ Forte e robusto, capace di resistere alle sollecitazioni meccaniche.
√ Riduce al minimo la perdita di energia e la generazione di calore.
√ Resistente all'ossidazione, garantendo longevità
√ Una buona conduttività termica favorisce un'efficace dissipazione del calore.
As the core conductive element of the battery system, the copper battery bus bar adopts C11000/C10100 high-purity copper (copper content ≥99.9%), forming a low-resistance channel through precision processing. Its conductivity is in line with GB/T 5581.1 standard, hard state (TMY) conductivity ≥ 97% IACS, soft state (TMR) up to 100% IACS, effectively controlling the voltage drop at 0.01724-0.01777Ω-mm²/m, suitable for 30-2000A wide range of current-carrying needs.
