In photovoltaic systems, cables are important components that connect photovoltaic modules with inverters, combiner boxes and other equipment, and they undertake the key task of power transmission. Photovoltaic cables need to maintain stable performance under various harsh environmental conditions, including resistance to UV rays, ozone, chemical corrosion, heat and cold.
