Main Benefits
For solar system designers, EPC contractors, distributors, and professional installers, the Solar DC Cable 1500V 4mm and 6mm offers measurable advantages across every phase of the project. Engineers benefit from clearly marked twin-core designs that simplify layout planning and documentation, while the use of cross-linked polyolefin sheathing offers added reliability in heat-prone areas.
EPC contractors reduce installation time with the cable’s flexibility and easy stripping performance, while the wide temperature range ensures operational stability across harsh climates. For distributors and resellers, the cable represents a trusted product from a certified brand with demand in residential and utility-scale solar projects.
Industrial and commercial users find the 6mm version particularly useful for long cable runs, as it minimizes voltage losses and heat buildup. In contrast, residential installers benefit from the lighter 4mm version for compact rooftop setups, ensuring both safety and neat cable routing with minimal effort.
These solar cables also support better cable management by reducing clutter and offering high abrasion resistance in densely packed installations. Whether routed through conduit, cable trays, or exposed to open sunlight, they retain integrity for decades.

Shanghai Kuka Special Cable Co., Ltd.
Shanghai Kuka is a leading Chinese manufacturer of specialized solar cables with a strong global footprint. With a focus on renewable energy, Kuka cables meet stringent certification standards and are tested to endure high temperatures, UV exposure, flame risks, and mechanical stress. Their commitment to innovation ensures installers receive products optimized for real-world challenges across all scales of PV deployment.
The 4mm cable supports up to 55A and is ideal for rooftop solar setups or short cable runs, while the 6mm cable supports up to 70A, making it better for commercial systems or installations requiring longer distances where voltage drop must be minimized.
Yes. Both 4mm and 6mm solar cable types are built with enhanced mechanical durability and insulation to support underground runs or enclosed conduit-based wiring in harsh environments.
Absolutely. The sheath is made from UV-resistant, cross-linked polyolefin, allowing the cable to perform reliably in long-term sunlight exposure.
Selection depends on system current, cable run length, and project scale. For residential systems with short connections, 4mm is often sufficient. For higher loads and long distances, the 6mm cable ensures safer current transmission and reduced voltage loss.
Both cables conform to TUV 2PfG/2642 and meet IEC 60332-1 flame resistance standards, ensuring they’re safe and compliant with global solar installation practices.
Twin-core cables simplify routing and reduce installation time, particularly in residential or small commercial projects. They also provide neater cable management, which is beneficial for system maintenance and fault detection.
