The 15kv 133% copper tape shielded armoured copper conductor single - core power cable is a high - performance cable specially designed for medium - voltage power transmission scenarios. It integrates a number of advanced technologies and structural designs, and has excellent electrical performance, mechanical protection capabilities and environmental adaptability, playing a key role in the power system.​ In terms of core specifications, "15kv" clearly indicates its rated voltage level, which is suitable for medium - voltage distribution networks and can efficiently realize power transmission between substations and distribution stations, as well as large - scale industrial equipment. The "single - core" structural design enables it to effectively reduce eddy current loss in high - voltage and large - current transmission, and is especially suitable for occasions where each phase conductor needs to be laid separately, such as high - voltage switchgear connections and underground direct - buried transmission lines. At the same time, it is also convenient for flexible installation in narrow spaces.​ The "copper conductor" is the conductive core of the cable, made of high - purity electrolytic copper. It has excellent conductive performance, which can ensure efficient current transmission and reduce line loss. Copper has good ductility and mechanical strength, so that the conductor is not easy to break during processing and laying, ensuring the long - term stable operation of the cable. Compared with aluminum conductors, copper conductors have a larger current - carrying capacity and can carry higher currents under the same cross - sectional area, which is suitable for scenarios with high requirements for transmission efficiency.​ "133% copper tape shielding" is a major highlight of this cable. The main function of the copper tape shielding layer is to evenly distribute the electric field, prevent local discharge caused by the concentration of the internal electric field of the cable, and at the same time can effectively suppress electromagnetic interference, avoid the cable from causing electromagnetic impact on external equipment, and also reduce the interference of external electromagnetic signals on the cable itself. "133%" means that the coverage area or thickness of the shielding layer exceeds the standard requirement by 33%, which further enhances the shielding effect and improves the anti - interference ability of the cable in complex electromagnetic environments, such as near substations and communication base stations.​ The "armoured" structure provides solid mechanical protection for the cable. The armoured layer is usually made of steel tape or steel wire, tightly wrapped around the outer layer of the cable. It can effectively resist external mechanical impacts, extrusion, tensile forces and other forces, preventing the cable from being damaged by external forces during laying, burying or operation. For example, when directly buried, the armoured layer can resist soil pressure, stone impact and gnawing by rodents; when laid through pipes, it can reduce friction and wear with the inner wall of the pipe, extending the service life of the cable.​ In conclusion, the 15kv 133% copper tape shielded armoured copper conductor single - core power cable, with its reasonable structural design, high - quality material selection and enhanced performance characteristics, is widely used in urban medium - voltage distribution network transformation, industrial plant power transmission, large - scale building power access and other scenarios, providing a reliable guarantee for the safe, stable and efficient operation of the power system.
