High-Voltage Power Supply Flexible Copper Busbar
High-Voltage Power Supply Flexible Copper Busbar
Material Specifications
■ Base Material: T2 high-purity copper foil (copper content ≥99.95%, conductivity ≥97% IACS), ensuring excellent electrical conductivity and thermal conductivity
■ Copper Foil Thickness: 0.05/0.1/0.2mm (0.1mm as standard), optional according to HV current requirements
■ Number of Layers: 20–100 layers (customized according to rated current, the more layers, the stronger the current-carrying capacity)
■ Cross-Section Dimensions: Width 20–100mm, total thickness 1–10mm, flexible adjustment to fit different installation spaces
■ Standard Length: 50–300mm (customizable, support non-standard length customization according to HV equipment layout)
■ Terminal Dimensions: Customized according to HV power supply equipment interface (aperture φ5–φ12mm, hole spacing accurately matched to avoid installation deviation)
Electrical Performance (HV Adaptation):
▶ Rated Current: 300–1500A (commonly used 600/800/1000A for HV power supply scenarios), suitable for different power levels of HV systems
▶ Contact Resistance: ≤40μΩ (@20℃, silver-plated terminals), ultra-low resistance to reduce energy loss and avoid overheating
▶ Insulation Withstand Voltage: AC 3000V/1min (no breakdown), effectively adapting to HV working environment and ensuring safe insulation
▶ Insulation Resistance: ≥500MΩ, strong insulation performance to prevent HV leakage and short circuit risks
