Asnjë informacion i shtuar.

Field of application: AT.1 Notes 1, 2 and 3 are normative in Austria: NOTE 1 The extent of the application of this standard is defined in Austrian „Elektrizitätsverordnung – ETV“. NOTE 2 The construction of lines with covered conductors (KUF) and reduced internal or external clearance is not permitted in Austria. 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 high voltage lines. These regulations are not valid for constructions of conductors or cables with integrated optical fibres independent from their function which do not have simultaneously the function of a conductor or an earth wire. For such constructions the normal additional load as from 4.3.3 and the exceptional additional loads with minimum 12 N/m are to be considered. For such constructions with metallic materials internal clearances as defined in 5.4.2.1 apply.
