The International Electrotechnical Commission’s IEC60228 standard covers the nominal cross-section areas for the conductors of various insulated cables.
IEC60228 covers solid and stranded copper, and aluminium and aluminium alloy conductors in cables for fixed installations and flexible copper conductors。 It also sets out the conductors’ requirements in terms of resistance values。
IEC 60228 covers the following international standard conductor sizes:
|Conductor Cross-Sectional Area Size|
The applicability of IEC60228 to a particular type of cable is as specified in the standard for the type of cable。 This standard does not apply to conductors in telecommunication cables。
