    The Application For Cu Clad Al Busbar

    1. Connection between busbars and branch cables

    The main busbars of the distribution cabinets are mostly made of copper strips, while the branch cables connected externally or led out internally are usually aluminum-core cables. The copper-aluminum transition strips serve as intermediate connectors to achieve stable conductivity and prevent electrochemical corrosion.

    2. Connection between components and busbars

    Connection terminals of core components like circuit breakers, contactors, and transformers are mostly made of copper. If internal branch lines use aluminum busbars or cables, transition busbars prevent direct copper-aluminum contact, ensuring stable resistance and lower overheating risk.

    3. Connection of different material busbars

    For balancing cost and performance, some large distribution cabinets use copper busbars for the main circuit and aluminum busbars for branch circuits. The transition busbar achieves a seamless, safe, and continuous current transmission between these sections.

    Frequently Asked Questions

    What is the composition and electrical conductivity of the Cu Clad Al Busbar?
    Our Cu Clad Al Busbar is composed of T2 Copper + 1060 Aluminum. It features an electrical conductivity of ≥80% IACS (at 20℃), ensuring high efficiency and reliable power transmission.
    Why is a copper-aluminum transition busbar necessary in distribution cabinets?
    Directly connecting copper and aluminum components can lead to electrochemical corrosion, high resistance, and thermal failure. Transition busbars act as safe connectors that eliminate direct contact risk, stabilizing circuit resistance.
    What are the working temperature and tensile strength limits of your busbars?
    The technical specifications include a tensile strength of ≥120MPa and a broad working temperature range of -40℃ to 150℃, making it suitable for demanding industrial applications.
    Do you support custom OEM/ODM designs and small sample orders?
    Yes, we fully support both OEM and ODM services. We also welcome small sample orders to help you verify the quality and specifications before placing bulk orders.
    What shipping methods and payment terms do you offer?
    We accept multiple payment methods including T/T, L/C, Western Union (WU), and PayPal. For shipping, we support Sea Freight, Air Freight, and various express services to ensure global delivery.
