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.
