Insulators for overhead lines with a nominal voltage above 1 kV - Ceramic insulators for a.c. systems - Characteristics of insulator units of the long rod type

Prescribes specified values for the electrical and mechanical characteristics and for the principal dimensions of string insulator units of the long rod type with insulating parts of ceramic material intended for a.c. overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It is also applicable to insulators of similar design, used in substations. Applies also to string insulator units: -of the long rod type either with a clevis at both ends for coupling with a tongue, or with a socket at both ends for coupling with a pin ball -with external metal fittings -for use on overhead lines situated in slightly polluted areas, and the creepage distances given in Tables I and II have been established accordingly -and insulators of similar design, used in substations. This standard may be regarded as a provisional standard for insulators for d.c. overhead lines. Note -For general definitions and methods of tests see EN 60383. -For dimensions of clevis and tongue couplings of string insulator units, see IEC 60471. -For dimensions of ball and socket couplings of string insulator units, see EN 60120.

Isolateurs pour lignes aériennes de tension nominale supérieure à 1 kV - Isolateurs céramiques pour systèmes à courant alternatif - Caractéristiques des éléments de chaînes d'isolateurs à fût long

Définit des valeurs spécifiées pour les caractéristiques mécaniques et électriques ainsi que pour les dimensions principales des éléments de chaînes d'isolateurs du type fût long ayant une partie isolante en céramique et destinés aux lignes aériennes fonctionnant en courant alternatif à une tension nominale supérieure à 1 000 V et à une fréquence au plus égale à 100 Hz. Elle est également applicable aux isolateurs du même type utilisés dans les sous-stations. S'applique aussi aux éléments des chaînes d'isolateurs: - du type fût long ayant à chaque extrémité soit une chape destinée à recevoir un tenon, soit un logement de rotule pour assemblage avec une rotule; - à armature métallique externe; - pour utilisation sur les lignes aériennes situées dans des régions à atmosphère peu polluée, les longueurs des lignes de fuite des tableaux I et II ayant été établies en conséquence; - et aux isolateurs du même type utilisés dans les sous-stations. Cette norme peut être considérée comme norme provisoire pour les isolateurs destinés aux lignes aériennes en courant continu. Note: - Pour les définitions générales et les méthodes d'essai, voir la EN 60383. - Pour les dimensions des assemblages à chape et tenon des éléments de chaînes d'isolateurs, voir la CEI 60471. - Pour les dimensions des assemblages à rotule et logement de rotule des éléments de chaîne d'isolateurs, voir EN 60120.

60433 © IEC:1998– 3 –INTERNATIONAL ELECTROTECHNICAL COMMISSION____________INSULATORS FOR OVERHEAD LINESWITH A NOMINAL VOLTAGE ABOVE 1000 V –Ceramic insulators for a.c. systems –Characteristics of insulator units of the long rod typeFOREWORD1)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 isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith 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 technical 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 60433 has been prepared by subcommittee 36B: Insulators foroverhead lines, of IEC technical committee 36: Insulators.This third edition cancels and replaces the second edition published in 1980 and constitutes atechnical revision.The text of this standard is based on the following documents:FDISReport on voting36B/180/FDIS36B/184/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.SIST EN 60433:2000

ScopeThis International Standard is applicable to string insulator units of the long rod type withinsulating parts of ceramic material intended for use in a.c. overhead power lines with anominal voltage greater than 1000 V and a frequency not greater than 100 Hz. It is alsoapplicable to insulators of similar design, used in substations.This standard is applicable to ceramic string insulator units of the long rod type, either with aclevis end fitting at both ends for coupling with a tongue, or with a socket end fitting at bothends for coupling with a pin ball.The object of this standard is to prescribe specified values for electrical and mechanicalcharacteristics, and for the principal dimensions of ceramic string insulator units of the longrod type.This standard is applicable to string insulator units for use on overhead lines situated in lightlypolluted areas, and the creepage distances given in table 1 have been established accordingly,using the IEC 60815 recommendation of 16 mm/kV for pollution level I. However, shortercreepage distances may be used in some non-polluted areas. If specific operating conditionsrequire or allow non-standard (longer or shorter) creepage distances, the mechanicalcharacteristics as well as the lengths L (see clause 4) of this standard should be used unlessthe need for exceptionally long creepage distances requires values of L greater than thosegiven in table 1. In the case of special requirements, e.g. very heavy polluted areas and forother particular or extreme environmental conditions, it may be necessary for certaindimensions to be changed.NOTES1
