High quality UL 4703 Photovoltaic PV Cable from SOWELLSOLAR® suppliers is tailored for applications in photovoltaic power generation systems, such as solar panels, and is suitable for both residential and commercial solar installations. With carefully selected insulation materials like cross-linked polyethylene (XLPE), the PV wire ensures electrical insulation and protection against environmental factors, meeting industry standards for safety, reliability, and performance in solar power systems.
Here are some key characteristics and considerations related to UL 4703 Photovoltaic PV Cable:
Single-Core Conductor Design: PV cables meeting the UL 4703 standard are typically single core cables. It’s made of copper, covered by insulation and sheath.
Insulation Material: The insulation of UL 4703 Photovoltaic PV Cable is designed to provide electrical insulation and protection against environmental factors. Common insulation materials include cross-linked polyethylene (XLPE).
Sheath Material: The outer jacket of the UL 4703 Photovoltaic PV Cable is crucial for protecting it from sunlight exposure, temperature variations, moisture, and other environmental conditions. UV-resistant and durable materials are often used for the jacket to ensure the longevity and reliability of the cable.
Temperature Ratings: PV cables must meet specific temperature ratings as per UL 4703. This includes ratings for both the maximum operating temperature of the conductor and the cable as a whole. These temperature ratings ensure that the cable can perform safely under the conditions commonly encountered in solar installations.
Sunlight Resistance: Given the outdoor nature of PV installations, the cable jacket is designed to resist the deteriorating effects of sunlight exposure over time.
Flexibility: While often installed in a fixed position in solar panels, PV cables need to be flexible enough to accommodate installation and potential movement within the system.
Compliance: UL 4703 certification ensures that the PV cable meets specific safety and performance standards. Compliance with UL standards is often a requirement for PV cable use in various solar projects.
