26、lectrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fiel
27、ds. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
28、 National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardizati
29、on (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representa
30、tion from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cann
31、ot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publication
32、s. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, acc
33、ess to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including ind
34、ividual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon
35、, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements o
36、f this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61394 has been prepared by IEC technical committee 7: Overhead electrical conductors. This first edition of IEC 61394 cancels and re
37、places the first edition of technical specification IEC/TS 61394 published in 1997. It constitutes a technical revision and now has the status of an International Standard. The text of this standard is based on the following documents: FDIS Report on voting 7/609/FDIS 7/613/RVD Full information on t

43、 conductors. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

45、on system Greases shall be designated 1A2or 1B2where A and B define the type of grease as follows: type A: products generally applied in the cold state, for example greases: semi-solid or solid products consisting essentially of a stabilized mixture of mineral or synthetic oil and thickeners such as
46、 metal soaps or inorganic compounds; type B: products generally applied in the hot state, for example petrolatum: semi-solid, or solid products made up essentially of microcrystalline waxes associated with small quantities of mineral oil and organic additives; 1is the lowest temperature in C below 0
47、 C at which the grease will perform the requirement of protection of the conductor from atmospheric corrosion; 2is the highest temperature, in C, at which the grease will perform to this requirement (achieve specified drop point or high temperature stability). Examples: 20A150 type A grease with a t
48、emperature 1of -20 C and 2of 150 C. 20B110 type B grease with a temperature 1of -20 C and 2of 110 C. The grease supplier shall provide a unique identifier for its grease, and shall retain details of its composition for future reference. The composition shall include manufacturing tolerance and shall remain unchanged while the grease is marketed under this specific identifier.
