Die meisten röhrenförmigen Aluminium-Sammelschienen von Hochspannungs- und Ultrahochspannungs-Stromverteilungsgeräten verwenden eine herkömmliche 6063-Legierung. Diese Aluminiumlegierung hat ein Medium (σb ≥ 205 MPa) und die elektrischen und physikalischen Eigenschaften können die Verwendungsbedürfnisse erfüllen. 6063 Aluminiumrohrsammelschiene
6063 Aluminiumrohrsammelschiene
Glatte Oberfläche, schönes Aussehen, einheitliche Größe
mainly used in the conductor connection between power grid transmission wires and substation transformers in my country's power construction projects, jumpers in transmission lines, connecting conductors in power equipment, and large current DC ice melting devices as overcurrent conductors. It replaces traditional the new conductors of rectangular, trough-shaped, rod-shaped busbars and flexible wires are one of the key equipment (materials) in the power transmission and transformation system, which is vital to the safe and reliable operation of the transmission and transformation system and power equipment effect.
