Product Details (Core Functions of Copper Busbars)
Copper busbars deliver three core functions in aerospace power systems:
Leveraging over 40 years of surface treatment expertise, we offer a full range of electroplating options (silver plating, nickel plating, gold plating, etc.) to ensure low contact resistance and excellent corrosion resistance. Additionally, we support custom insulation coatings (polyimide, ETFE, heat-shrink tubing, etc.) to provide reliable insulation protection in vacuum and high-altitude environments, meeting the stringent safety and weight-reduction requirements of aerospace applications.
Laminated Busbars: Low parasitic inductance suppresses transient overvoltage, protecting sensitive avionics; flat profile saves cabin space; custom L/Z shapes available.
Braided Busbars: Ultimate flexibility with an extremely small bending radius, effectively absorbing vibration and thermal expansion displacement; the braided structure distributes stress against high-frequency fatigue; excellent heat dissipation; high tolerance simplifies assembly.
Rigid Busbars: Manufactured from high-purity T2 copper via rolling or extrusion, offering extremely high current-carrying capacity and strong mechanical rigidity; ideal for main-circuit busing and fixed connections with superior reliability.
Frequently Asked Questions (FAQ)
They fulfill three critical roles: high-current transmission between generators and onboard systems, equipotential bonding and grounding for structural safety, and absorption of dynamic vibration and thermal stresses during flight.
Braided busbars provide exceptional flexibility with an ultra-small bending radius. Their multi-wire construction distributes mechanical stress to prevent fatigue failure caused by high-frequency flight vibration and thermal expansion displacement.
Comprehensive electroplating solutions are offered, including silver plating, nickel plating, and gold plating. These coatings reduce contact resistance and provide long-lasting corrosion resistance in harsh operational conditions.
Custom insulation materials such as polyimide, ETFE, and specialized heat-shrink tubing are utilized to deliver dependable electrical insulation in vacuum and high-altitude settings while meeting tight weight restrictions.
Laminated busbars feature low parasitic inductance, effectively suppressing transient overvoltages to protect delicate avionics. Furthermore, their compact flat profile and custom L/Z shapes maximize cabin space utilization.
Rigid busbars are fabricated from high-purity T2 copper using rolling or extrusion processes, ensuring ultra-high current-carrying capacity, structural rigidity, and maximum operational reliability for main-circuit connections.
