COPPER BUSBARS
COPPER BUSBARS
DULICO provides copper busbars manufactured from electrolytic copper with high copper content, Cu ≥ 99.90%. The products feature a bright and flat surface, stable electrical conductivity, and mechanical strength suitable for applications in industrial electrical systems, electrical cabinets, switchgear, and power distribution systems.
Our products comply with ISO 9001, ISO 14001, and ISO 45001, and are widely used in switchboards, substations, renewable-energy systems, and industrial electromechanical equipment.
Key Characteristics
Một số đặc tính quan trọng của đồng thanh cái có thể kể đến như:
- Superior electrical conductivity: Low resistivity enables high-current transmission with minimal energy loss.
- Thermal stability & heat dissipation: Ensures reliable performance under continuous high-load operation.
- High mechanical integrity: Resistant to bending, distortion, and mechanical stress during installation and operation.
- Corrosion & oxidation resistance: Surface can be tin-plated, nickel-plated, or silver-plated depending on application requirements.
- Wide dimensional range: Available in flat bars, rounded-edge bars, solid round bars, and thin coils to support diverse assembly and connection needs.
Applications
Copper busbars are widely used in sectors requiring high electrical performance and long-term reliability, including:
Manufacturing Process
DULICO copper busbars are produced through a fully integrated, closed-loop manufacturing process:
Raw material selection → Casting → Rolling / Friction extrusion → Straightening → Surface treatment → Quality inspection → Packaging
Each production stage is closely monitored to ensure dimensional accuracy, electrical conductivity, and surface quality for every batch.
