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 stage is tightly controlled to ensure dimensional accuracy, electrical performance, and surface perfection for every batch.
