In the international cable industry, the letter "N" at the beginning of a cable designation carries significant technical and regulatory meaning. However, many engineers encounter confusion when comparing cables marked with N (without brackets) versus (N) (with brackets). This distinction is fundamental to understanding whether a cable is manufactured to German national standards or European harmonised standards. 在国际电缆行业中，电缆型号开头的字母"N"具有重要的技术和法规含义。然而，许多工程师在比较标有N（不带括号）和(N)（带括号）的电缆时会感到困惑。这种区别对于理解电缆是按照德国国家标准还是欧洲协调标准制造的至关重要。

IEC 60502 is an international standard published by the International Electrotechnical Commission (IEC) that sets out the specification for power cables with extruded insulation. The standard covers cables with voltage ratings from 1 kV (Um = 1.2 kV) up to 30 kV (Um = 36 kV), designed for fixed installations such as distribution networks and industrial installations. This widely recognized standard serves as a primary reference for cable manufacturers worldwide and forms the basis for numerous national and regional cable standards.

What is IEC 60502 Cable?

IEC 60502 對導體類型、絕緣材料和護套化合物提供了詳細規格。絕緣材料包括 PVC（最高溫度 70°C）、XLPE、EPR 和 HEPR（均為最高 90°C）。導體類別包括第 1 類（實心）、第 2 類（絞合）和第 5 類（柔性），尺寸範圍從 1.5 mm² 到 1600 mm²。護套化合物包括 PVC、PE 和用於防火敏感區域的無鹵素材料。XLPE 絕緣的標稱厚度從 0.6/1 kV 的 1.0 mm 到 18/30 kV 的 8.0 mm 不等。

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.

What is DIN VDE 0276 Cable?

VDE 0276 電纜的技術規格對於正確選擇和安裝至關重要。XLPE 絕緣電纜允許的連續工作溫度高達 90°C，短路溫度可達 250°C，優於 PVC 絕緣電纜的 70°C 和 160°C。導體採用符合 IEC 60228 第 2 類標準的絞合壓縮圓形銅或鋁導體。導體屏蔽層為擠出的半導電材料，最小厚度 0.3mm，在 90°C 時體積電阻率不超過 500 Ω·m。彎曲半徑要求根據電纜類型不同而變化：無金屬護套電纜為 15 倍外徑，帶鋁護套電纜為 30 倍外徑。
