Qingzhou floating solar cable is a highly flexible AD7-rated waterproof cable specifically engineered for floating photovoltaic power stations. It is compatible with all major solar connectors and has obtained multiple international certifications, including TÜV’s latest 2PfG 2750/09.20, UL, IEC, CE, and RETIE. The cable also complies with UL4703, IEC62930, and EN50618 standards, ensuring reliable performance in floating PV applications.
Designed as a versatile single-core PV cable, it meets a wide range of requirements in the solar industry. It operates safely and stably in harsh outdoor environments—such as lakes, coastal areas, and mountainous regions—where high temperature, high humidity, and strong salt corrosion are common.
As a critical component of any photovoltaic system, high-quality cabling ensures long-term, efficient, and safe operation. Superior connectivity reduces failure rates and helps lower maintenance and operational costs throughout the system’s service life.
