Xi’an city, Shaanxi Province, China – August 26, 2026 – <\/strong>Xi’an Zipeng Technology product offerings as discussed below.<\/p>\n

Rigid Copper Busbar<\/p>\n

Advantages<\/p>\n

    \n
  1. Solid integrated structure ensures stable conductivity, low DC resistance and excellent heat dissipation, resulting in lower heat generation under high\u2011current working conditions.<\/li>\n
  2. High dimensional accuracy and neat appearance, suitable for cabinet layout with little deformation after installation.<\/li>\n
  3. Simple processing procedures. Lower material and processing costs for the same cross\u2011sectional area, ideal for mass production.<\/li>\n
  4. Multiple surface treatments are available, including tin\u2011plating, nickel\u2011plating, silver\u2011plating and insulation coating, for long service life.<\/li>\n<\/ol>\n

    Disadvantages<\/p>\n

      \n
    1. High rigidity and cannot be bent freely; no deformation\u2011buffering capacity.<\/li>\n
    2. Unable to compensate for assembly tolerances. Stress caused by equipment vibration and thermal expansion & contraction transfers directly to connecting bolts, which may lead to loose bolts, terminal overheating and even cracking in severe cases.<\/li>\n
    3. Difficult to assemble when misalignment occurs between two devices, not suitable for floating connection applications.<\/li>\n<\/ol>\n

      Flexible Copper\u2011Foil Busbar (Mainstream for energy\u2011storage industry)<\/p>\n

      Advantages<\/p>\n

        \n
      1. Bendable intermediate copper\u2011foil layers offer good flexibility, compensate for assembly misalignment and adapt to narrow and complex installation spaces.<\/li>\n
      2. Absorbs equipment vibration and relieves mechanical stress from thermal expansion & contraction, protecting bolts and device terminals against stress\u2011induced damage.<\/li>\n
      3. Convenient for transition connection between equipment with high assembly tolerance, widely used in PCS, battery modules and charging piles.<\/li>\n
      4. Flexible insulation protection options such as heat\u2011shrink tubes and insulation wrapping.<\/li>\n<\/ol>\n

        Disadvantages<\/p>\n

          \n
        1. Contact thermal resistance exists between stacked copper\u2011foil layers. Heat dissipation is slightly poorer than solid rigid copper busbar at the same cross\u2011sectional area.<\/li>\n
        2. Polymer diffusion welding is required. More production steps lead to higher overall cost compared with rigid copper busbar.<\/li>\n
        3. Welded terminals are critical weak points. Poor welding quality may cause cold solder joints and overheating issues.<\/li>\n
        4. Not resistant to excessive pulling force; repeated heavy bending may break copper foils.<\/li>\n<\/ol>\n

          Supplementary note: Braided copper busbar Advantages: Bendable in all directions, mainly used for earthing and vibration absorption. Disadvantages: Low current\u2011carrying capacity, rarely adopted in high\u2011current main circuits.<\/p>\n

          Selection Summary<\/p>\n

          \u2011 For fixed cabinet\u2011internal installation without vibration and cost\u2011effective requirement → Rigid copper busbar \u2011 For inter\u2011device connection with vibration and assembly\u2011tolerance compensation requirement → Copper\u2011foil flexible busbar<\/p>\n
