❓ Frequently Asked Questions
Q1 What is a copper-aluminum transition busbar and why is it used in UPS systems?
A copper-aluminum transition busbar is a composite conductor that bonds a copper layer (T2, ≥99.9% purity) to an aluminum layer (1070, ≥99.7% purity) through a metallurgical process. It is used in UPS systems to enable reliable electrical connections between copper and aluminum conductors, reducing weight and cost while maintaining high conductivity — ideal for data centers, computer rooms, and industrial power systems.
Q2 What sizes and dimensions can be customized for the copper-aluminum transition busbar?
We offer fully customizable dimensions: thickness from 3mm to 16mm, width from 15mm to 200mm (up to 500mm for certain configurations), and any length based on your equipment structure. Special-shaped sizes, bending angles (45°, 90°, multi-angle), drilling patterns, and milling requirements are all supported based on customer drawings or samples.
Q3 What surface treatment options are available for the busbar?
For the copper end, we offer tin-plating, nickel-plating, silver-plating, and zinc-plating. For the aluminum end, options include anodizing, powder coating, or natural finish. An overall insulation coating is also available as an optional upgrade, suitable for environments with higher protection requirements such as humid computer rooms.
Q4 What is the minimum order quantity, and do you support sample orders?
Yes, we fully support sample orders and small-batch trial production with no strict minimum order quantity requirement. This allows customers to verify fit, dimensions, and performance before committing to mass production. Delivery time is negotiable based on the quantity and complexity of processing required.
Q5 What quality standards does the copper-aluminum transition busbar comply with?
All our copper-aluminum transition busbars are manufactured in compliance with GB/T30586-2014, the Chinese national industry standard for copper-clad aluminum busbars. Each product undergoes strict pre-delivery inspection including electrical resistance testing, tensile strength testing, dimensional verification, and appearance inspection. Test reports can be provided upon request.
Q6 Is OEM/ODM service available for different UPS brands and equipment models?
Yes, we fully support OEM and ODM services. Our copper-aluminum transition busbars are compatible with various brands of UPS equipment including online UPS, rack-mounted UPS, modular UPS, EPS emergency power supplies, and high-frequency switching power supplies. Customers can provide CAD drawings, PDF files, physical samples, or equipment model numbers for us to develop a tailored solution.
