Frequently Asked Questions
1. Why are specialized cable assemblies necessary for solar installations?
Solar environments are unique due to constant UV radiation, extreme temperature fluctuations, and moisture. Standard wiring will degrade quickly. LEX uses TUV/UL certified XLPO insulation and tinned copper conductors, ensuring our solar cable assemblies maintain high conductivity and structural integrity for the entire lifespan of the PV system.
2. How does LEX guarantee the 25-year service life of PV harnesses?
Durability is engineered into every step. We utilize IATF 16949 quality protocols and conduct rigorous environmental stress tests, including UV aging and thermal cycling. By using specialized anti-corrosion materials and IP68-rated sealing technology, we ensure our interconnects resist ozone, acids, and alkalis found in industrial or coastal environments.
3. Does LEX support high-voltage (1500V) DC solar systems?
Yes. As solar technology shifts toward higher voltages to reduce LCOE, LEX provides 1500V DC rated cable assemblies that comply with the latest safety standards. Our manufacturing process ensures low contact resistance and high dielectric strength, preventing arcing and energy loss in high-voltage utility projects.
4. Can LEX provide custom DFM support for unique solar projects?
Absolutely. As a National High-Tech enterprise, we offer Design for Manufacturing (DFM) support. Our engineers collaborate with your team to optimize cable lengths, connector selection, and branching logic, reducing material waste and simplifying on-site installation for complex floating solar or tracker systems.
5. What are the benefits of LEX’s Texas-based support for solar OEMs?
For our North American partners, our sales office in Texas, USA provides real-time technical consultation and localized project management. This bridges the gap between our high-efficiency manufacturing in Xiamen and your project site, ensuring seamless communication and on-time delivery for critical energy infrastructure.
