Application
Copper UL 4703 PV cable is a high-performance single-conductor cable designed to meet the various needs of the solar industry. The cable is widely used in the connection of photovoltaic modules, especially the connection to the module junction box, and the cable routing in the balance of system (BOS) integration. With its excellent weather resistance and electrical performance, UL 4703 PV cable can effectively support the stability and safety of power transmission in solar power generation systems, and is particularly suitable for long-term use outdoors and in harsh environmental conditions. This cable not only meets strict industry standards, but also ensures the efficient operation and reliability of the system.
Feature
UL 4703 PV cable is a high-performance wire specifically designed for use in photovoltaic (solar) power systems, offering versatility and reliability in both AC and DC applications. This wire is available in voltage ratings of 600V, 1000V, or 2000V, making it suitable for a wide range of solar installations. It is designed to withstand extreme environmental conditions, with temperature ratings of 90°C to 150°C for dry environments and 90°C for wet conditions, ensuring robust performance in varying climates.

FAQ
Q: What is UL 4703?
Q: What is the difference between THWN and PV wire?
PV wire has a UV-resistant, weatherproof design that can withstand extreme temperatures, ranging from -40°C to +90°C (-40°F to 194°F), which makes it ideal for solar installations.
It typically has a durable UV-resistant outer jacket that is designed for use in direct sunlight and can withstand prolonged exposure to UV rays without degradation. The insulation in PV wire is typically cross-linked polyethylene (XLPE) or similar material, making it more resistant to environmental factors than THWN.
