concentric conductor cable

Medium voltage reeling cables conforming to DIN VDE 0250-813 employ a systematic letter coding system that communicates precise information about cable construction, materials, and performance characteristics. Within this nomenclature, each letter position corresponds to a specific structural element or material property, enabling engineers to identify critical design features at a glance.[1][2] 符合DIN VDE 0250-813标准的中压卷筒电缆采用系统性的字母编码系统,传达电缆结构、材料和性能特性的精确信息。在该命名法中,每个字母位置对应特定的结构元素或材料属性,使工程师能够一目了然地识别关键设计特征。

DIN VDE 0276 is the widely used German standard for cables with extruded insulation used in power distribution systems. Developed by the VDE (Verband der Elektrotechnik, Elektronik und Informationstechnik e.V.), this comprehensive standard covers a significant percentage of power cables used across the European continent, establishing construction requirements, dimensional specifications, and test methods for both low voltage (0.6/1 kV) and medium voltage (up to 18/30 kV) power cables.
