is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the nominal cross-sectional areas, in the range 0.5 mm² to 2 500 mm², for conductors in electric cables and flexible cords [1].
This is the core requirement. For instance, a 10 mm² Class 2 copper conductor must not exceed a resistance of 1.83 Ω/km . iec 60228 pdf free download
Permitted for fixed installations (Classes 1 and 2). Aluminum is lighter and more cost-effective than copper but requires larger cross-sectional areas to achieve the same current-carrying capacity. Understanding Conductor Resistance
The core value of IEC 60228 lies in its precise technical tables. Instead of focusing solely on the physical diameter of a wire, the standard prioritizes . 1. Nominal Cross-Sectional Area The standard lists standard sizes in square millimeters ( mm2m m squared ), such as 1.5 mm2m m squared mm2m m squared mm2m m squared mm2m m squared , up to 1000 mm2m m squared and beyond. 2. Maximum Electrical Resistance This public link is valid for 7 days
Stranded copper conductors (Class 2) for fixed installations.
Flexible copper conductors for cords and cables, suited for applications requiring moderate flexibility. Can’t copy the link right now
The international standard is the foundational document governing the cross-sectional areas, material requirements, and resistance values for conductors in insulated electrical cables. Whether you are an electrical engineer, a cable manufacturer, or a procurement specialist, understanding this standard is critical for ensuring electrical safety, system efficiency, and regulatory compliance.
To ensure the use of accurate, up-to-date, and non-corrupted technical data, it is important to access the standard through recognized and official channels. 1. Official IEC Webstore
