Frequently Asked Questions
What's the difference between T1, T2, and T3 copper grades?
T1 represents the highest purity copper (99.95%+), ideal for applications requiring maximum conductivity. T2 is standard electrical-grade copper (99.90%+), suitable for most industrial uses. T3 contains slightly more impurities but offers excellent performance for cost-sensitive applications while maintaining good conductivity.
Why choose tinned copper over bare copper busbars?
Tin plating provides multiple benefits: it prevents oxidation and corrosion (especially in humid or salty environments), improves solderability for connections, reduces surface oxidation that increases resistance over time, and provides better performance in high-temperature applications.
Can you customize busbar dimensions beyond the standard range?
Yes, as a factory-direct manufacturer, we specialize in custom dimensions. We can produce busbars with thickness from 70mm to 800mm and widths from 20mm to 800mm, with specific length requirements accommodated through our cutting and processing services.
What processing services do you offer?
We provide precision cutting to specified lengths and professional bending services to create custom shapes and angles for complex installation requirements. All processing maintains the integrity of the tin plating and material properties.
What is the lead time for custom orders?
Standard products ship within 7-14 days. Custom specifications typically require 15-30 days depending on complexity and order quantity. We provide detailed production timelines with each quotation.
What packaging do you use for export?
We use standard seaworthy packaging with protective wrapping, wooden crates, or pallets as needed to ensure safe transportation. Custom packaging solutions are available for specific logistic requirements.
