Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of EIW/QZYL grade over standard enamel?
A: EIW/QZYL grade Polyesterimide offers significantly higher thermal endurance (Class 200, 200°C), superior chemical resistance, and better dielectric strength, making it suitable for demanding applications like inverter-duty motors and high-temperature environments. -
Q: Can you provide wires to specific international standards (e.g., NEMA, IEC, JIS)?
A: Yes. While our standard production aligns with common specifications like IEC 60317, we can customize wire properties and testing to meet specific international standards upon request. Please provide your detailed requirements. -
Q: What are the packaging options available?
A: We typically supply on wooden or steel spools. Packaging size, spool type, and weight can be customized based on your production needs and shipping preferences. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ varies depending on wire diameter and specific requirements. We strive to be flexible. Contact us directly to discuss your volume needs. -
Q: Do you offer different colors for identification?
A: Yes. While natural is standard, other colors are available optionally to suit customer identification systems. -
Q: What is the typical lead time for orders?
A: Lead time depends on order size, specifications, and current production schedule. We prioritize efficient production and shipping, especially for established partners. Contact us for an accurate estimate. -
Q: How does aluminum wire compare to copper wire in terms of conductivity?
A: Aluminum has approximately 61% of the conductivity of copper for the same cross-section. However, its lighter weight and lower cost often make it an attractive alternative, especially when slightly larger diameters are feasible in the design. Our EIW grade ensures the insulation performs reliably with aluminum. -
Q: Can you provide test reports or samples?
A> Yes. We can provide standard test reports (e.g., dimensional checks, breakdown voltage) with shipments. Sample requests are welcome for evaluation purposes.
