The 2, 3, 4-Core Armoured AC Copper Power Cable with XLPE insulation is a reliable power transmission cable, available in sizes 4mm², 6mm², 10mm², 16mm², 25mm², and 35mm², performing excellently in various power transmission scenarios such as industrial, construction, and municipal fields.​ This cable uses 99.9% high-purity electrolytic copper as the conductor, with excellent conductivity and a low resistance value of 0.0172Ω/mm²·m, effectively reducing transmission losses and ensuring efficient power transmission. The insulation layer is made of cross-linked polyethylene (XLPE), which, after special cross-linking treatment, has a wide temperature resistance range (-40℃ to 105℃), and strong aging resistance and chemical corrosion resistance. Even in humid, acid-base environments, it can maintain good insulation effect with an insulation resistance stably above 1000MΩ, greatly reducing the risk of electric leakage. The armored layer is made of 0.3-0.5mm thick hot-dip galvanized steel strip, tightly wrapped by spiral winding technology, enhancing the cable's mechanical strength and corrosion resistance. It can withstand a lateral pressure of 10kN/m and an impact force of 5kN, suitable for underground direct burial, tunnel laying, industrial plants, construction projects, and other places with cable protection requirements. For example, a car manufacturing plant's workshop power lines use 25mm² 4-core cables, which can resist equipment vibration and oil pollution erosion.​ 2-core cables are mostly used in single-phase circuits, such as household electricity branches and small household appliance power supply; 3-core cables are applicable to three-phase power equipment like water pumps and fans; 4-core cables, including a neutral wire, are more suitable for three-phase distribution systems needing a neutral wire, such as the central air-conditioning distribution in office buildings. Different cross-sectional specifications meet different power requirements: 4mm² to 10mm² are suitable for medium and low-power equipment and indoor wiring, such as residential indoor lighting and socket lines; 16mm² to 35mm² can be used for power supply of high-power industrial equipment and main line transmission, such as power supply for large injection molding machines and community distribution trunks.​ In terms of packaging, it uses a combination of moisture-proof kraft paper and galvanized iron reels, with a wrapping film on the outer layer, protecting the cable from moisture and deformation during transportation and storage; various transportation methods such as land and sea transportation are supported, and the distribution plan is optimized according to the order quantity to ensure timely delivery; 1-10 meter samples and detailed test reports can be provided for customers to test; a professional technical team responds within 72 hours for after-sales service, offering installation guidance and fault troubleshooting to ensure trouble-free use.​
