Bridgold In Chemical & Metallurgical Engineering Equipment

With over 40 years of expertise in copper busbars and braided wires, we possess in-depth knowledge of the challenges posed by high temperature, high humidity, strong corrosion, heavy dust, and continuous high-current operation in chemical and metallurgical plants. From material selection and surface protection design to insulation withstand and temperature-rise validation, we offer customized solutions throughout the entire design cycle, ensuring long service life and high reliability in harsh environments.

Copper busbars deliver three core functions in chemical and metallurgical equipment:

High-current transmission – connecting rectifiers, electrolytic cells, electric furnace transformers, and distribution systems;

Equipotential bonding and grounding – equalizing enclosure and structural potentials for safe protection;

Absorbing vibration and thermal expansion – preventing rigid connections from fatigue failure due to equipment vibration and severe temperature fluctuations.

Leveraging over 40 years of surface treatment expertise, we offer a full range of electroplating options (tin plating, silver plating, nickel plating, etc.) to enhance corrosion resistance and contact performance. Additionally, we support custom insulation coatings (epoxy powder coating, PVC dip molding, heat-shrink tubing, etc.) to meet insulation protection requirements across various voltage levels, delivering comprehensive safety and durability for demanding industrial environments.

Laminated Busbars: Low parasitic inductance suppresses switching overvoltage, protecting power devices; flat profile saves cabinet 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 installation.

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, delivering superior cost-effectiveness for standardized mass production.
