FAQs

Q1: Why is the adjacent wall thickness intentionally unequal?

The unequal wall design allows engineers to direct more coolant flow to specific areas of the conductor that experience higher thermal loads, or to accommodate asymmetric slot geometries in the rotor. This ensures uniform cooling efficiency across the entire winding.

Q2: What does "deviation of more than 2mm" mean in practice?

It means the difference in wall thickness between two adjacent sides of the hollow profile can exceed 2 mm. For example, one wall may be 4 mm thick while the adjacent wall is 6.5 mm thick. This asymmetry is precisely controlled to meet customer specifications.

Q3: How do you maintain high accuracy on OD and ID with such complex asymmetry?

We utilize multi‑axis laser measurement systems (ODAC/UMAC) and custom‑designed drawing tooling. Real‑time feedback adjusts die position during processing to ensure both outer geometry and inner hole dimensions remain within specified tolerances.

Q4: What is the maximum single wire length available?

The standard maximum single wire length is 10 meters. Longer lengths may be available depending on the specific cross‑sectional dimensions and wall thickness configuration. Please inquire with your requirements.

Q5: Can this product be bent or formed for coil winding?

Yes. Despite the asymmetric wall thickness, the silver‑bearing copper material offers excellent ductility and can be bent and formed using standard winding equipment without cracking or deformation of the internal channel.
