COPPER BUSBAR

COPPER BUSBAR
DULICO supplies high-quality copper busbars manufactured from electrolytic tough pitch copper (Cu ≥ 99.90%), ensuring excellent electrical conductivity, flatness, mechanical strength, and a bright, clean surface finish.
Our products are manufactured under ISO 9001, ISO 14001, and ISO 45001 management systems, and are widely used in electrical panels, substations, renewable energy systems, and industrial electromechanical equipment.
KEY FEATURES
- Superior electrical conductivity: Low resistivity ensures efficient current transmission with minimal energy loss.
- Excellent heat resistance & dissipation: Maintains stability under high continuous load.
- High mechanical strength: Resistant to bending or deformation during installation and operation.
- Anti-oxidation & corrosion resistance: Tin, nickel, or silver plating available upon request for enhanced protection.
- Flexible configurations: Available in flat bars, rounded edges, solid round rods, or thin coils, tailored to various connection and fabrication needs.
APPLICATIONS
Thanks to copper’s outstanding electrical and mechanical properties, DULICO busbars are widely applied in:






MANUFACTURING PROCESS
DULICO’s copper busbars are produced through a fully controlled and traceable process:
Raw material selection → Casting → Rolling / Extrusion → Straightening → Surface treatment → Quality inspection → Packing.
Each production stage is monitored under strict standards to ensure dimensional accuracy, conductivity consistency, and surface quality for every batch.

PRODUCT SPECIFICATIONS
DULICO offers a wide range of busbar sizes — from small flat bars to rounded, solid, and custom-machined types according to drawings and customer specifications.
