Solar DC Cable (H1Z2Z2-K / H1ZZZ-K) is a high-performance photovoltaic cable designed for long-term DC power transmission in demanding outdoor solar environments. It is primarily used to connect solar modules to inverters, junction boxes, and other PV system components in residential, commercial, and utility-scale solar installations. The fine-stranded tinned copper conductor provides low electrical resistance, excellent conductivity, and reliable current flow, ensuring stable energy transmission and minimal power loss over extended periods.
The cable features a dual-layer insulation system, offering exceptional resistance to mechanical stress, UV radiation, moisture, and extreme temperature variations. This robust protection ensures the cable maintains reliable performance under continuous sunlight, temperature cycling, and environmental exposure, extending its service life and reducing maintenance requirements. Its flexible design allows for easy installation along rooftops, cable trays, conduits, or PV arrays with complex routing, simplifying the integration of renewable energy systems.
H1Z2Z2-K / H1ZZZ-K solar cable is manufactured in accordance with IEC 62930 and EN 50618 international standards, meeting global safety, fire performance, and operational reliability requirements. It is ideal for applications where long-term stability, environmental resistance, and compliance with photovoltaic regulations are critical. This cable ensures consistent energy output, protects system components, and supports the efficient operation of solar power installations, making it a reliable and durable choice for modern solar energy projects.
