FAQs
1. What is a single-layer UL 4703 tinned copper PV wire?
This is a high-voltage photovoltaic (PV) wire with a tinned copper conductor and single-layer insulation, certified under UL 4703. It is rated for 2KV DC and used for interconnecting components in solar power systems.
2. What are the benefits of using tinned copper in PV cables?
Tinned copper resists corrosion better than bare copper, especially in humid, salty, or chemically aggressive environments. It also maintains excellent electrical conductivity and extends cable life in outdoor solar applications.
3. What does UL 4703 certification guarantee?
UL 4703 certification ensures the cable meets strict U.S. safety standards for voltage capacity, flame resistance, UV stability, and long-term performance in solar installations.
4. Where is this single-layer PV wire typically used?
It is ideal for interconnections between solar modules, inverters, combiner boxes, and charge controllers in both rooftop and utility-scale photovoltaic systems.
5. Is this cable suitable for outdoor or underground installations?
Yes. The UV-resistant insulation allows for outdoor use, and it is durable enough for conduit and direct burial installations, depending on site requirements.
6. What is the voltage and temperature rating of this cable?
This cable is rated for 2000V DC, with a temperature range of -40°C to +90°C in wet conditions, and up to +150°C in dry conditions, supporting reliable use in harsh environments.
