Cable U-1000 Rvfv Arvfv Vvfv is a comprehensive multi-specification aluminum-copper composite cable with cross-sections including 4X25mm² and 4X95mm², widely applicable to industrial power distribution, building power transmission, underground laying and other scenarios. Its conductor adopts an aluminum-copper composite structure, with a high-purity aluminum core and an outer layer coated with high-conductivity copper. It not only retains the lightweight advantage of aluminum (about 40% lighter than pure copper cables) but also improves conductivity through the copper layer (conductivity up to 85% IACS or more), effectively reducing transmission losses. The insulation layer is made of XLPE material with a temperature resistance of -40℃ to 105℃. After cross-linking treatment, the insulation resistance is stable above 1000MΩ, with excellent anti-aging performance, capable of resisting erosion from harsh environments such as moisture, acids and alkalis. The armor layer uses 0.3-0.5mm thick hot-dip galvanized steel tape (Sta), forming a tight protective layer through spiral winding technology, with lateral pressure resistance of 10kN/m and impact resistance of 5kN. The outer PVC sheath further enhances weather resistance, able to withstand ultraviolet rays, oil pollution and mechanical wear, suitable for complex environments such as industrial plants, underground direct burial and tunnel projects.​ In specific applications, the 4X25mm² specification has a current-carrying capacity of about 80-100A, suitable for power supply of small and medium-sized industrial equipment (such as injection molding machines, fans) and branch lines of high-rise buildings; the 4X95mm² has a current-carrying capacity of 180-220A, meeting large-capacity transmission needs such as large production lines, substation outgoing lines and urban power grid branches. The packaging uses moisture-proof kraft paper to wrap the cable, wound on a galvanized iron reel and covered with wrapping film to ensure moisture and pressure resistance during transportation and storage; it supports land transportation, sea transportation and less-than-truckload distribution, and can provide 1-10 meters of samples and test reports including voltage withstand and insulation tests on demand; after-sales service provides a 2-year warranty, responds to fault consultations within 72 hours, and a professional team can provide installation guidance and on-site troubleshooting services to fully ensure safe use.
