solar cable source factory
As the "dual carbon" strategy continues to advance, distributed commercial and industrial solar systems, large-scale ground-mounted power plants, and integrated "fishery-solar" and "agriculture-solar" projects are springing up everywhere. While solar modules and inverters garner significant market attention, solar cables—acting as the "energy arteries" of the system—are often underestimated. A substandard solar cable can expose a power plant to risks such as current leakage, overheating, and fire, directly shortening the plant's lifespan and eroding long-term power generation revenue. Today, we take a look at the front lines of solar cable manufacturing to understand the core value that a primary cable factory brings to solar projects.
The DC side of a solar system is subjected to continuous 1500V high-voltage DC, with cables exposed to outdoor environments around the clock. They must withstand multiple harsh conditions, including intense UV radiation, extreme diurnal temperature fluctuations, coastal salt spray, mountainous humidity, and acid-alkali corrosion. Unlike standard indoor power cables, compliant solar cables rely on three critical technical pillars: high-purity tinned copper conductors, irradiation-crosslinked low-smoke zero-halogen (LSZH) insulation and sheathing, and rigorous factory testing. These standards can only be consistently met by primary manufacturers that operate their own production lines.
As a primary manufacturer specializing in cable R&D and production, Yuejiaxin Wire & Cable Company operates standardized workshops equipped with complete extrusion lines and testing laboratories. The company maintains an integrated, closed-loop production process—spanning raw material intake, conductor stranding, insulation extrusion, irradiation modification, finished product testing, and warehousing/shipping—eliminating intermediaries and delivering clear advantages. The factory offers a comprehensive solar cable product line, featuring mainstream models such as PV1-F and H1Z2Z2-K. These products comply with international standards (IEC62930, EN50618) and hold certifications including TÜV, covering common cross-sectional areas ranging from 1.5mm² to 35mm² (1.5, 2.5, 4, 6, 10, 16, 25, and 35mm²).
Our products are widely compatible with residential distributed solar systems, commercial and industrial rooftop solar installations, large-scale ground-mounted PV power plants, and DC connections for energy storage systems. We supply projects for both domestic and overseas markets, meeting the regulatory standards of regions such as Europe, the Americas, Southeast Asia, and the Middle East. Yuejiaxin adheres to a philosophy of avoiding short-term, low-cost, non-standard products; instead, we leverage stable raw material standards, mature irradiation processes, and rigorous quality control systems to provide partners with cost-effective, comprehensive solar cable supply solutions. We welcome domestic EPC contractors, renewable energy O&M companies, and solar cable exporters to visit our factory to inspect our production lines, submit samples for testing, and discuss long-term strategic partnerships.
