Modelo: Power Control & Distribution System-Rigid Copper Busbar
Marca: htd
Origin: PORCELANA
Lugar de origen: PORCELANA
Posicionamiento del producto:
La barra colectora de salida trifásica del motor HTD es un componente conductor central en el sistema de propulsión eléctrica de vehículos de nueva energía, responsable de la transmisión eficiente de energía CA trifásica U/V/W entre el controlador del motor y el motor de propulsión. Utilizando cobre T2 de alta conductividad (pureza ≥99,9%) o una estructura compuesta de cobre y aluminio, logra una solución de conexión compacta con baja inductancia (≤12nH) y alta capacidad de transporte de corriente (corriente continua 200A-3000A) a través de un diseño laminado multicapa y tecnología de integración de aislamiento. El producto admite un funcionamiento estable a largo plazo de -40 °C a 105 °C, con una temperatura máxima soportada de 180 °C y un aumento de temperatura de ≤35 K a la corriente nominal. Su diseño de blindaje electromagnético y protección contra vibraciones mejora significativamente el rendimiento EMC y la confiabilidad del sistema de accionamiento eléctrico, lo que lo convierte en un componente clave que garantiza una salida eficiente del motor.
