This product is a 4-core aluminum-copper composite power cable with XLPE/PVC insulation, available in various sizes (10mm² to 300mm²) and rated currents (16A-30A), combining the cost-effectiveness of aluminum with the reliability of copper, suitable for medium-low voltage distribution systems.

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.

This product is a 600V Aluminum Copper Service Ser Cable, available in three specifications: 2AWG, 1/0AWG, and 2/0AWG, suitable for power transmission and distribution in low-voltage power distribution systems.​ The cable adopts an aluminum-copper composite conductor design, combining the lightweight and cost-effectiveness of aluminum with the high conductivity of copper. It can operate stably at the 600V voltage level to meet different power requirements. The 2AWG specification has a moderate conductor cross-sectional area, suitable for power supply of branch circuits in small and medium-sized equipment, residential and commercial buildings; the 1/0AWG specification has a higher current-carrying capacity, which can be used for medium-sized distribution trunks, such as small industrial machinery and main circuits of multi-storey buildings; the 2/0AWG specification has stronger current-carrying capacity, suitable for high-load scenarios, such as industrial equipment clusters and incoming cables of large electrical facilities.​ The cable insulation layer is made of materials with excellent aging resistance and temperature resistance, complying with relevant safety standards, and can resist mechanical wear and environmental erosion in daily use. Its compact structure is convenient for laying and installation, and it is widely used in indoor and outdoor fixed wiring, building power distribution, industrial auxiliary circuits and other fields, providing an efficient and economical transmission solution for power systems.

3X25mm², 4X25mm², 5X25mm² aluminum or copper power cables are commonly used power transmission products in low-voltage distribution systems. With flexible core configurations and stable performance, they are widely applied in industrial plants, commercial buildings, residential quarters, municipal engineering and other fields. Their rated voltage is mostly 0.6/1kV, suitable for AC 50/60Hz power grids, and can meet the power transmission needs of medium and low-power equipment clusters and branch lines.​ In terms of conductor materials, copper core cables are made of high-purity electrolytic copper (purity ≥99.95%) through compact stranding process. The DC resistance at 20℃ is ≤0.727Ω/km, which has excellent conductivity, low power transmission loss, and is suitable for scenarios with high requirements for conduction efficiency. Aluminum core cables are made of high-purity aluminum (purity ≥99.5%), also processed by compact stranding process. The DC resistance at 20℃ is ≤1.208Ω/km, with relatively low cost and light weight, which is more advantageous in long-distance laying and cost-sensitive projects.​ The insulation layer usually adopts cross-linked polyethylene (XLPE) or polyvinyl chloride (PVC) materials. The XLPE insulation layer can withstand a temperature of up to 90℃, with a volume resistivity of ≥1×10¹⁴Ω·cm, excellent insulation performance, and can withstand an ambient temperature difference of -40℃ to 90℃, suitable for complex environments such as high temperature and humidity; The PVC insulation layer can withstand a temperature of 70℃, has good flame retardancy and mechanical properties, low cost, and is suitable for general dry environments. The insulation layer has uniform thickness, eccentricity ≤15%, and partial discharge ≤10pC, ensuring the safety of power transmission.​ In terms of core configuration, 3X25mm² cables are composed of 3 conductors of 25mm², mostly used in three-phase power lines to supply power to three-phase equipment such as motors and water pumps; 4X25mm² cables include 3 phase lines and 1 neutral line, suitable for distribution scenarios with both three-phase and single-phase equipment, such as central air conditioners and lighting systems in shopping malls; 5X25mm² cables add 1 grounding line on the basis of 4 cores, which can better ensure electrical safety, and are often used in places with high safety requirements, such as branch lines in hospitals and data centers.​ The current-carrying capacity of this series of cables varies depending on the material and laying method. When laid in air, the current-carrying capacity of 25mm² copper core cable is about 85A, and that of aluminum core cable is about 65A; When laid underground, the current-carrying capacity of copper core cable is about 70A, and that of aluminum core cable is about 55A. Such current-carrying capacity can meet the power needs of various equipment. For example, 3X25mm² copper core cable can supply power to three-phase motors of about 30kW, and 4X25mm² cable can support the operation of multiple single-phase equipment of 2-3kW at the same time.​ During the production process, both copper core and aluminum core cables undergo strict quality control. The conductor stranding accurately controls the pitch and pressure to ensure a tight structure; The insulation layer extrusion uses advanced extrusion equipment to ensure uniform thickness and no defects such as bubbles and cracks. Finished cables must pass multiple tests such as power frequency withstand voltage (3kV/5min without breakdown), insulation resistance test, mechanical performance test, etc. Each batch of products is accompanied by a detailed test report to ensure that the quality meets relevant standards.
