kV)FOREWORD1)The IEC(International Electrotechnical Commission)is a worldwide organization for standardization comprisingall national electrotechnical committees(IEC National Committees).The object of the IEC is to promoteinternational co-operation on all questions concerning standardization In the electrical and electronic fields.Tothis end and in addition to other activities,the IEC publishes International Standards.Their preparation iscntrusted to technical committees;any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work.International,governmental and non-governmental organizations lialsingwith the IEC also participate in this preparation.The IEC collaborates closely with the International Organizationfor Standardization(ISO)in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on tochnical matters express,as nearly as possible,aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards,technical reports or guides and they are accepted by the National Committees in that sense.4)in order to promote international unification,IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards.Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights.The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60502-1 has been prepared by subcommittee 20A:High-voltagecables,of IEC technical committee 20:Electric cables.This consolidated version of IEC 60502-1 is based on the first edition(1997)(documents20A/318/FDIS and 20A/347/RVD and its amendment 1(1998)documents 20A/382/FDIS and20A/384/RVD.It bears the edition number 1.1.A vertical line in the margin shows where the base publication has been modified byamendment 1.IEC 60502 consists of the following parts,under the general title:Power cables with extrudedinsulation and their accessories for rated voltages from 1 kV(Um=1,2 kV)up to 30 kV(Um=36 kV):-Part 1:Cables for rated voltages of 1 kV(Um=1,2 kV)and 3 kV(Um-3,6 kV);-Part 2:Cables for rated voltages from 6 kV(Um=7.2 kV)up to 30 kV(Um=36 kV);-Part 3:Reserved;-Part 4:Test requirements on accessories for cables with rated voltages from 6 kV(Um=7,2 kV)up to 30 kV(Um=36 kV).Annexes A,B and C form an integral part of this standard.Copyright por International Electrotechnical Commissionhu Sep 11 15:20:31

1:Cables for rated voltages of 1 kV(Um 1,2 kV)and 3 kV(Um 3,6 kV)1 ScopeThis part of IEC 60502 specifies the construction,dimensions and test requirements of powercables with extruded solid insulation of rated voltages 1 kV and 3 kV for fixed installations suchas distribution networks or industrial installations.Cables for special installation and service conditions are not included,for example cables foroverhead networks,the mining industry.nuclear power plants(in and around the containmentarea),submarine use or shipboard application.2 Normative referencesThe following normative documents
