33、 relevant subcommittee: Fach(normen)ausschuss L2. The Austrian NC has prepared this Part 3-1 of EN 50341 listing the Austrian nationalnormative aspects, under its sole responsibility, and duly passed it through theCENELEC and CLC/TC11 procedures.NOTE The final draft prEN 50341-3-1:2000 was published

34、 as Entwurf VE/NORMEN 50341-3-1:2000-08 on Austrian national level. At the end of deadline, 2000-09-15, the supposedchanges have been discussed during the 82nd meeting of Fach(normen)ausschuss L“. The agreedchanges are incorporated in this document.3. This EN 50341-3-1 is normative in Austria and in

35、formative for other countries;4. This EN 50341-3-1 has to be read in conjunction with EN 50341-1, hereinafterreferred to as Part 1. All clause numbers used in this Part 3-1 correspond to those ofPart 1. Specific subclauses, which are prefixed AT“, are to be read as amendmentsto the relevant text in

36、Part 1. Any necessary clarification regarding the application ofPart 3-1 in conjunction with Part 1 shall be referred to the Austrian NC who will, incooperation with CLC/TC11 clarify the requirements.When no reference is made in Part 3-1 to a specific subclause, then Part 1 applies.5. In the case of

37、 boxed values“ defined in Part 1, amended values (if any) which aredefined in Part 3-1 shall be taken into account in Austria.However any boxed value, whether in Part 1 or Part 3-1, shall not be amended in thedirection of greater risk in a Project Specification.6. The Austrian NC declares in accorda

38、nce with subclause 3.1 of Part 1 that this Part 3-1follows the Empirical Approach“ (subclause 4.3), and that consequently subclause4.2 General Approach“ is not applicable for Austria.7. The national Austrian standards/regulations related to overhead electrical linesexceeding 1 kV (A.C.) are identifi

39、ed/listed in 2.3.NOTE All national standards referred to in this Part 3-1 will be replaced by the relevant EuropeanStandards as soon as they become available and are declared by the Austrian NC to be applicable andthus reported to the secretary of CLC/TC 11.N 50341-3-1:2001BS E- 4/67 - Austria - 5/5

For KUF-lines the prescriptions for clearances as from 5.4.2.1 apply.NOTE 3 In addition to the text from Part 1 the following applies:These regulations also cover telecommunication lines which are carried on supports of OH

42、high voltagelines. These regulations are not valid for constructions of conductors or cables with integrated optical fibresindependent from their function which do not have simultaneously the function of a conductor or an earthwire. For such constructions the normal additional load as from 4.3.3 and
