U-1000 Series Cables Summary This series of cables includes models such as Ar2V, Axmk, Na2xy, Axv, and Yakxs, with a rated voltage of 1kV. It covers four specifications: 4X25mm², 4X35mm², 4X120mm², and 4X240mm², suitable for low-voltage power distribution scenarios. "4X" represents a four-core structure. The cross-sectional area of a single core increases from 25mm² to 240mm², corresponding to different current-carrying capacity requirements (about 85A for 25mm², 110A for 35mm², 230A for 120mm², and 400A for 240mm² at an ambient temperature of 25℃), which can match equipment of different powers. The 1kV rated voltage complies with low-voltage power grid standards and can be directly connected to 380V/220V systems. The conductors mostly use high-purity electrolytic copper with excellent conductivity; the insulation layer and sheath are made of temperature-resistant and corrosion-resistant materials (such as polyvinyl chloride or cross-linked polyethylene), adapting to various indoor and outdoor environments. The four-core structure is suitable for three-phase four-wire systems and is widely used in industrial equipment, building power distribution, municipal facilities and other scenarios to meet different power transmission needs.
