Power Transmission: Photovoltaic cables are key components in solar power systems, connecting solar panels to inverters. Their conductors (typically copper or aluminum) transmit direct current (DC) through the directional movement of electrons, while the insulation layer (such as cross-linked polyethylene) prevents current leakage or short circuits.
Environmental Adaptability: Photovoltaic cables must possess properties such as UV resistance, high-temperature resistance, and corrosion resistance to withstand harsh outdoor environments with long-term exposure. For example, their insulation materials must remain stable within a temperature range of -40℃ to 90℃ to avoid performance degradation due to temperature changes.
Low-Loss Design: To reduce energy loss during power transmission, photovoltaic cables typically employ low-resistance conductors and optimized cross-sectional area designs. For example, for long-distance transmission, the conductor cross-sectional area is increased to reduce resistance, thereby improving the overall system efficiency.
