Photovoltaic DC Cable PV1-F/H1Z2Z2K: The "Blood Vessels" of Power in the New Energy Era, Pioneering Industry Standard Upgrades

PV1-F / H1Z2Z2-K photovoltaic DC cable is a special cable specially designed for the DC side of photovoltaic systems. It is a single-core round flexible cable, made of tinned copper conductor, with matte and uniform red/black weather-resistant outer sheath printed with serial numbers and specifications.It features excellent flexibility and easy bending.

  It is widely used for DC power transmission between photovoltaic modules, combiner boxes, inverters and energy storage equipment, suitable for 1000V–1500V DC systems, with an outdoor service life of ≥25 years and certified by TUV, CE and other international authorities.

Below is the detailed description of the photovoltaic DC cable PV1-F/H1Z2Z2-K:

Core Product Structure：

Conductor: 

Made of Category 5 flexible copper, composed of stranded tin-plated annealed copper wires; exhibits excellent electrical conductivity, flexibility, and ease of installation, while also possessing anti-oxidation and acid/alkali resistance properties, making it suitable for long-term operation in complex outdoor environments.

Insulation Layer:

 Made of irradiation-crosslinked polyolefin material, it withstands DC 1500V high voltage, has a temperature resistance rating of 120°C to 125°C, provides corona protection, offers high insulation strength, and exhibits low transmission loss.

External Sheath:

  Made of specialized weather-resistant polyolefin material, it is UV-resistant, withstands extreme temperatures (40°C to120°C), and features low-smoke, halogen-free flame retardancy. With an outdoor service life exceeding 25 years, it aligns perfectly with the lifecycle of photovoltaic modules. 

Comprehensive scenario coverage: from deserts to rooftops, suitable for a wide range of scenarios

Cntralized PV Power Station: Ideal for desert and mountain projects; 1500V high voltage reduces transmission loss and system cost.

Distributed PV System: Perfect for factory rooftops, residential rooftops and agro-PV complementary projects; flexible and easy routing for complex layouts.

Energy Storage Power Station: DC connection inside container units and between battery clusters; low smoke halogen-free & flame retardant, meeting high fire safety standards for energy storage.

Special environments: fishery-photovoltaic integration, coastal saline-alkali soils, and high-altitude regions with intense ultraviolet radiation; featuring weather and corrosion resistance for long-term stable operation.

Common specifications include： 1×4mm², 1×6mm², and 1×10mm², with the 6mm² variant being the most widely adopted standard suitable for most photovoltaic applications.
