Bridgold In Aerospace & Aviation

With over 40 years of expertise in copper busbars and braided wires, we possess in-depth knowledge of the challenges unique to aerospace equipment—extreme temperature variations, intense vibration and shock, vacuum environments, and stringent weight reduction requirements. From material selection and structural optimization to thermal cycling and fatigue validation, we offer customized solutions throughout the entire design cycle, strictly complying with aviation industry standards to ensure absolute reliability and long service life under demanding conditions.

Copper busbars deliver three core functions in aerospace power systems:

High-current transmission – connecting generators, power distribution units, and onboard equipment for stable power supply;

Equipotential bonding and grounding – equalizing enclosure and structural potentials for system safety;

Absorbing vibration and thermal stress – preventing rigid connections from fatigue failure due to flight-induced vibration and extreme temperature changes.

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.
