Frequently Asked Questions (FAQ):
What materials are used in the transition busbar?
We use high-purity T2 Copper (≥99.9%) and 1070 Aluminum (≥99.7%) to ensure excellent electrical conductivity, mechanical stability, and long-term reliability for UPS systems.
Can I customize the sizes and bending configurations?
Yes, we offer fully customizable sizes with thicknesses ranging from 3mm to 16mm and widths from 15mm to 200mm. We also support custom bending angles (45°, 90°, and multi-angle special shapes) and specific drilling options.
What surface treatments are available for the copper and aluminum ends?
The copper end can be tin-plated, nickel-plated, or silver-plated. The aluminum end can be anodized, powder-coated, or left in its natural color. An overall insulation coating is also available as an option.
What is the standard copper-to-aluminum ratio for the composite?
The industry standard ratio is 20%:80% by volume (45%:55% by mass), which optimizes both conductivity and cost-effectiveness. Special ratios can be customized upon request.
Do your transition busbars comply with international quality standards?
Yes, all our customized products comply with the GB/T30586-2014 implementation standard. We maintain strict quality control and can provide traceable test reports upon delivery.
