1. conductor material:
- Copper purity ≥ 99.95% (e.g. T2 copper or high purity oxygen-free copper), surface silver plating layer thickness is usually 1-5μm.- Conductivity ≥ 97.6% IACS (International Annealed Copper Standard), better than ordinary copper busbar.

2. Electrical performance:
- Carrying capacity increased by more than 30% (due to the silver layer to reduce the contact resistance).- Temperature rise limit: Silver-plated busbar allows temperature rise up to 70K (bare copper is 60K), suitable for high load scenarios.

3. Physical properties:
- Tensile strength ≥15%, can withstand high-frequency vibration and mechanical shock.- Corrosion resistance: passed 1800 hours of salt spray test, suitable for humid, chemical, and other harsh environments.

4. Dimensional specifications:
- Common thickness 1.5-25mm, width 10-250mm, support customized shaped rows (such as C-type female rows).

Silver plated copper bus bar Production process:

1. Raw material processing:

• Copper rods are processed into copper strips by the top-induction method or cold-rolling process, and the surface is milled to remove the oxidized layer.

2. Pre-plating treatment:

•  Alkaline etching: 50-80 ℃ sodium hydroxide solution to clean the oil.
• Acid cleaning activation: dilute sulfuric acid to remove oxides and enhance the adhesion of the plating layer.

3. Silver plating process:

• Pre-silver plating: current density 1-3A/dm², energized for 5-10 seconds to form the bottom layer.
• Main silver plating: current density 0.5-3A/dm², temperature 15-35 ℃, plating 1.5-2.5 hours, and the thickness of the silver layer is uniform.

4. Post-treatment:

• Dip anti-silver discoloration agent (such as benzotriazole) to prevent sulfidation and oxidation.
• Laser marking, automatic inspection, and packaging.

은도금 구리 버스 바 특징:

1. High conductivity: the conductivity of silver (6.3×10⁷ S/m) is higher than that of copper (5.96×10⁷ S/m), which reduces transmission losses.
2. Oxidation resistance: silver layer isolates copper from oxygen, avoiding the generation of copper oxide and keeping low contact resistance.
3. High-frequency adaptability: under skin effect, the silver layer improves the stability of high-frequency signal transmission, suitable for 5G, data center and other scenarios.
4. High Temperature Resistance: Support -65℃ to 250℃ working temperature, short time resistance 300℃, better than tinned copper row.
5. Environmentally friendly: Halogen-free materials, no release of toxic gases in case of fire, passes UL94 flame retardant standard.

버스바에 은도금을 하는 이유는 무엇입니까?

버스바는 종종 여러 가지 이유로 은도금을 합니다.

• Reduced contact resistance: silver conductivity is better than copper and tin; silver plating reduces contact resistance by 30%, improving current-carrying capacity and energy efficiency.
• Resistance to corrosion and oxidation: Silver is less susceptible to corrosion in humid, sulfur/chlorine environments, avoiding performance degradation caused by oxidation of the copper substrate.
• Optimization of high-frequency performance: high-frequency current is concentrated on the surface of the conductor (skin effect), and the silver layer reduces signal attenuation and ensures communication quality.
• Extended service life: the silver plating layer is wear-resistant, suitable for frequent plugging and unplugging scenarios (such as switchgear connectors), reducing maintenance costs.
• Temperature rise control: allows a higher temperature rise (70K vs. 60K for bare copper), adapting to the needs of high-current transmission.
