The DC cable of the photovoltaic power generation system is an important component of the solar power station, undertaking the task of transmitting electrical energy from the photovoltaic module to the inverter. This type of cable needs to have excellent weather resistance and be able to withstand ultraviolet radiation, high and low temperature changes for a long time. Cross-linked polyethylene insulation and special elastomer sheath are adopted to ensure stable performance within the temperature range of -40℃ to 120℃. The cable conductor is made of tin-plated copper wire to enhance its corrosion resistance. In addition, photovoltaic cables must also pass strict acid and alkali resistance and salt spray resistance tests to ensure reliable operation in various harsh environments. The latest type of photovoltaic cables also integrate monitoring functions, which can monitor the line temperature and insulation status in real time.
Wind power generation cables are mainly used inside the tower and nacelle of wind turbines and need to withstand continuous alternating stress. This type of cable adopts a special conductor twisting process and an elastomer sheath, capable of withstanding over 10 million torsional cycles. The cable structure design fully considers the requirements of tear resistance and wear resistance. The sheath material is selected from special formula polyurethane or chlorosulfonated polyethylene, which has good mechanical strength and oil resistance. Wind power cables used in cold regions also need to pass a -40℃ low-temperature bending test to ensure flexibility in extreme environments. The new generation of wind power cables has also added flame retardant requirements, meeting the strict safety standards of offshore wind power platforms.
