A2XY/2XY series cable is a high-performance single-core cable launched by Chinese electrical power cable suppliers, designed specifically for power transmission systems. Its core advantages lie in flexible conductor material options, stable insulation performance, and a wide range of cross-sectional specifications, which can meet the power transmission needs of various fields such as industry, construction, and municipal engineering. The cross-sectional specifications of this series cover 1x16mm² to 1x150mm², and the conductor materials include copper and aluminum, providing diversified solutions for different budgets and application scenarios, making it an ideal power transmission carrier that balances economy and reliability.​ In terms of structural design, A2XY/2XY cables adopt differentiated conductor configurations: the copper core version uses high-purity electrolytic copper, which has excellent conductivity, low resistance, and low loss, suitable for precision power systems with high requirements for transmission efficiency; the aluminum core version uses high-purity aluminum as the conductor, which is lighter in weight and lower in cost, suitable for long-distance overhead laying or large-scale projects sensitive to cost. Both conductors are wrapped with a polyvinyl chloride (PVC) insulation layer, which has good insulation resistance (not less than 100MΩ·km at room temperature) and voltage resistance (able to withstand 1kV power frequency withstand voltage test without breakdown), effectively preventing current leakage and ensuring electrical safety.​ The polyvinyl chloride material of the insulation layer also endows the cable with excellent environmental adaptability, which can operate stably in the working temperature range of -15℃ to 60℃, and has certain chemical corrosion resistance, able to resist erosion from acid-base mist, grease, etc. in daily environments. In addition, the single-core structure design of the cable simplifies the laying process, especially suitable for scenarios that require separate wiring, such as internal main lines of buildings, outdoor overhead lines, and industrial equipment power supply circuits.​ In terms of performance parameters, the current-carrying capacity of this series of cables varies according to cross-sectional specifications and conductor materials: the 1x16mm² copper core cable has a current-carrying capacity of about 85A when laid in air and 105A when laid underground; the 1x150mm² copper core cable can reach 310A when laid in air and 380A when laid underground; the current-carrying capacity of the aluminum core version is slightly lower than that of the copper core of the same specification, but it can still meet the needs of most industrial and civil scenarios. At the same time, the cable has excellent mechanical properties, with a tensile strength of ≥12MPa and an elongation at break of ≥150%, which can adapt to laying operations such as bending and dragging, and the outer sheath has certain wear resistance, extending the service life.​ In terms of application fields, small-sized (1x16mm² - 1x50mm²) cables are suitable for residential area power distribution, small industrial equipment power supply, and indoor lighting lines; medium and large-sized (1x70mm² - 1x150mm²) cables can meet the needs of medium and high-power scenarios such as main lines of high-rise buildings, power transmission networks in industrial parks, and municipal road lighting systems. The aluminum core version is particularly suitable for outdoor overhead lines, such as rural power grid transformation and farmland irrigation power supply; the copper core version is more suitable for places with strict requirements on power supply stability such as hospitals and data centers.​ As a key product of Chinese electrical power cable suppliers, A2XY/2XY cables strictly comply with national standards such as GB/T 12706, and have passed multiple tests including conductor resistance, insulation thickness, and aging resistance to ensure stable product quality. Its diversified specifications and material options, reliable electrical performance, and wide environmental adaptability make it a preferred solution with both practicality and cost-effectiveness in power engineering.
