19、 4002:CEI 9 INTRODUCTION IEC 60228 is intended as a fundamental reference standard for IEC Technical Committees and National Committees in drafting standards for electric cables, and to the National Committees in drafting specifications for use in their own countries. These committees should select
20、from the tables of this general standard the conductors appropriate to the particular applications with which they are concerned and either include the applicable details in their cable specifications or make appropriate references to this standard. In preparing this edition the main objects have be
21、en to incorporate IEC 60228A into it and maintain a simplified yet informative standard so far as is compatible with technical and economic considerations. Page 4 EN 60228:2005 82206 4002:CEI 11 CONDUCTORS OF INSULATED CABLES 1 Scope This International Standard specifies the nominal cross-sectional
22、areas, in the range 0,5 mm2 to 2 500 mm2, for conductors in electric power cables and cords of a wide range of types. Requirements for numbers and sizes of wires and resistance values are also included. These conductors include solid and stranded copper, aluminium and aluminium alloy conductors in c
23、ables for fixed installations and flexible copper conductors. The standard does not apply to conductors for telecommunication purposes. The applicability of this standard to a particular type of cable is as specified in the standard for the type of cable. Unless indicated to the contrary in a partic
24、ular clause, this standard relates to the conductors in the finished cable and not to the conductor as made or supplied for inclusion into a cable. Informative annexes are included giving supplementary information covering temperature correction factors for resistance measurement (Annex B) and dimen
