This article involves multiple cables of 0.6/1kV voltage level, with specific specifications and related information as follows:​ In terms of specifications: They include 4×25mm², 4×35mm, 4×150mm, etc. The 4×25mm² cable has a small cross - section and is suitable for small and medium - power scenarios, such as distribution branch lines of small buildings. The 4×35mm cable has an improved current - carrying capacity and can be used for power supply of medium - sized equipment or building trunk lines. The 4×150mm cable has a relatively large cross - section and is suitable for high - power transmission, such as main lines of industrial workshops.​ Model identification: U - 1000, Ar2V, Axmk, Na2xy, Na2xh, Na2xh - J, Axv, Yakxs, etc. may be brand, insulation or structure identifiers, implying different performances. For example, some models may have weather resistance and flame - retardant properties, suitable for outdoor or special environments.​ Common features: All meet the 0.6/1kV voltage requirement, and most are of 4 - core design, which can transmit electricity and ensure safety at the same time. In terms of materials, they are likely to use copper or aluminum conductors with corresponding insulation layers, taking into account both conductivity and insulation performance, and are widely used in power distribution fields such as construction, industry and outdoor.
