Photovoltaic

With the continuous growth of global energy consumption, the supply and environmental issues of traditional energy sources have become increasingly prominent, particularly the severe pollution caused by fossil fuel consumption. As a result, countries worldwide are actively developing renewable energy to replace conventional energy sources and achieve sustainable development. Solar photovoltaic (PV) power generation systems, as a clean and renewable energy solution, have garnered widespread attention and application. Photovoltaic cables, serving as a critical component in these systems, have also experienced rapid development and adoption.

Photovoltaic cables are primarily used to connect solar panels, inverters, and other system components. They play a vital role in solar PV power generation systems, ensuring the safe and efficient transmission of electricity from solar panels to the grid or end-users.

Photovoltaic cables must meet stringent requirements for weather resistance, temperature range, mechanical strength, electrical performance, flame retardancy, and ease of installation.

• Weather Resistance: Photovoltaic cables are typically made of high-quality materials that can withstand UV radiation, ozone, moisture, and other environmental factors, ensuring long-term durability and reliability even when exposed to outdoor conditions.
• Wide Temperature Range: Since solar panels may be installed in locations with extreme temperature variations, photovoltaic cables are designed to operate across a broad temperature range (e.g., -40°C to +90°C or higher), making them suitable for diverse climatic conditions.
• High Mechanical Strength: To endure stresses such as stretching and bending during installation, as well as mechanical wear during daily use, photovoltaic cables feature reinforced structures and abrasion-resistant outer sheaths, enhancing their tear and compression resistance.
• Stable Electrical Performance: Photovoltaic cables exhibit excellent conductivity and low resistivity, minimizing energy loss. They also maintain superior insulation properties, ensuring stable electrical performance even in humid environments.
• Flame Retardancy: For safety considerations, many photovoltaic cables are treated with flame retardants, making them resistant to ignition and capable of self-extinguishing in case of fire, thereby reducing the risk of fire spread.
• Ease of Installation: Photovoltaic cables are designed with installation convenience in mind, such as pre-terminated configurations or flexible constructions, enabling quick and accurate connections during on-site installation.
