What are the requirements for photovoltaic cables

Photovoltaic cables are mainly used in solar photovoltaic power plants to connect various components and transmit the electricity generated by photovoltaic power generation systems. In order to ensure the normal operation and long-term reliability of its functions, photovoltaic cables need to meet the following requirements:

1. UV resistance: Photovoltaic cables need to withstand high intensity sunlight radiation, so they require good UV resistance performance.

2. High temperature resistance: Under sunlight, photovoltaic cables can generate high temperatures, so it is necessary to have good high temperature resistance performance to ensure their long-term stable operation.

3. Cold resistance performance: Photovoltaic cables also need to work in extremely cold environments, such as photovoltaic power plants operating in polar regions. At this point, photovoltaic cables are required to have good cold resistance performance.

4. Fire resistance: Due to the potential fire hazards in photovoltaic power plants, photovoltaic cables also need to have certain flame retardant properties.

5. Strength and impedance matching: Photovoltaic cables need to have a certain mechanical strength, and when transmitting electricity, they need to match the impedance of the power generation components and the power grid to ensure efficient transmission of electricity.

6. Product Certification: Photovoltaic cables also need to pass various international standards and certifications, such as IEC, UL, etc., to verify their product quality and reliability.
