Common questions
What is the minimum order quantity and lead time?
Minimum order quantity is 100 ft (30 m). In stock — typical lead time 7-10 business days. Large-volume and OEM programs may qualify for reduced minimums and blanket order pricing.
What certifications and documentation are provided?
This product carries UL AWM 3135, CSA Certified, RoHS Compliant, CE Marked certifications and complies with UL AWM 3135, IEC 60245. Every shipment includes a Certificate of Compliance. UL yellow cards, RoHS/REACH declarations, production test reports, and full batch traceability are available on request.
Can this cable be used outdoors or in extreme temperatures?
Rated 200°C. For outdoor or UV-exposed installations, specify the UV-resistant formulation. Beyond the rated temperature range, PTFE/FEP fluoropolymer (extreme heat and chemical exposure) or TPE (cold flex) constructions are available — contact us with your environmental parameters.
Do you offer custom lengths, colors, or configurations?
Yes. Custom colors (2,500 ft min), custom print legends, gauge changes, shielding, and multi-conductor assemblies are available. OEM programs with blanket orders can negotiate minimums below the standard threshold. Send requirements to support@shanghaiunicorncable.com.
