Our bending and extruding coated rigid busbar is a composite power transmission component made of high purity copper, aluminum or aluminum alloy as the core conductor, molded by precision extrusion process and covered with multi-layer protective coatings (e.g. PVF, PVC, etc.). Its structural design provides both rigid support strength and controllable bending characteristics, enabling efficient and stable transmission of high currents (up to 5000A) in complex installation environments. The core application scenarios cover new energy power generation systems (e.g. photovoltaic power stations, wind farms), industrial electrical equipment, intelligent building power distribution networks and other fields to meet the demand for high-strength, high-security power connections.

Production Process of Rigid Busbar:
- Material Preparation: Raw material inspection (copper/aluminum bar) → Cut to standard length → Surface cleaning and pretreatment.
- Extrusion Molding: Heating to 250-350°C → Die extrusion (rectangular/round cross-section) → Cooling and shaping.
- Tegaĵo: Surface coating with PVF or PVC → Curing at high temperature → Multi-layer compounding (fireproof layer, waterproof layer, insulation layer).
- Processing and Inspection: Punching/bending → Tin or silver plating on contact surfaces → Conductivity and mechanical strength testing.
- Pakado kaj Livero: Shock-proof packaging → Qualified marking → Logistics transportation.

FAQ
Q1: How to choose the bending radius?
A: According to the cross-section size and material, flat bending radius ≥ 2 times the thickness, vertical bending radius ≥ 1 times the width, refer to GB/T 5585.1 standard.
Q2：How to repair the coating damage?
A: Re-spray the special coating material after partial grinding and do insulation resistance test.
Q3：Does it support customized size?
A：Support non-standard cross-section and length customization, need to provide application scenarios and electrical parameters.
Q4: What should I pay attention to when installing?
A: Avoid mechanical damage to the coating, and the bolt tightening torque should be in accordance with the specification (e.g. 25N-m for M10 bolts).
Q5: Advantages compared with cables?
A: High current-carrying capacity, less space occupation, long life, low maintenance cost, suitable for fixed installation scenarios.
