H1Z2Z2-K Solar Cable
Farwalk’s H1Z2Z2-K Solar Cables are the ultra-resilient lifeblood of modern photovoltaic systems. Strictly manufactured to the European EN 50618 standard and TÜV certified, these cables are engineered to endure 25+ years of intense solar radiation, extreme temperature fluctuations, and harsh outdoor exposure while maintaining peak 1500V DC power delivery.
Manufactured in accordance with EN 50618. The conductor is high-purity tinned annealed copper (Class 5), ensuring superior conductivity and long-term corrosion resistance. It features a dual-layer insulation and jacket made of cross-linked halogen-free polyolefin (XLPO). This thermoset construction ensures the cable will not melt or crack under extreme thermal load.
The definitive choice for connecting solar panels (PV modules) to inverters and string combiner boxes in residential, commercial, and utility-scale solar farms. Specifically designed for fixed and mobile installations in rooftop and ground-mount PV systems where durability against UV and chemicals is paramount.
