Overhead electrical lines exceeding AC 1 kV. National Normative Aspects (NNA) for CZECH REPUBLIC (based on EN 50341-1:2012)

Status : Current   Published : June 2015



1.1 General (ncpt) CZ.1 New overhead line The new overhead line is considered a brand new electric overhead line with nominal voltage exceeding 1 kV AC, between the points A and B. The new branch line of the existing overhead line shall be considered a new overhead line except for a junction support for which the specific requirements shall be defined in the Project Specification. The extent of application of this standard in respect of reconstruction, relaying and extension of existing overhead lines shall be determined in the Project Specification. Simultaneously, the Project Specification shall determine, which of the previous national standards shall be used and to what extent they shall be used for the project in question. 1.2 Field of application (ncpt) CZ.1 Field of application The requirements of this standard shall be adopted, where applicable (e.g. requirements on loads, external clearances, etc.), for telecommunication cables as well. In case of overhead line under the design stage, parties concerned shall agree the extent of the application of this standard. Overhead line under construction may be completed according to standards valid during the design stage of the line. The parties concerned shall agree any possible application of certain clauses of this standard. (ncpt) CZ.2 Installation of telecommunication equipment on supports Provisions of this standard also apply to the telecommunication equipment and devices (aerials, dish antennas, etc.) which are installed on individual supports of overhead power lines, especially in terms of wind and ice loads on such installed equipment. Design and installation has to respect requirements of the utility operating the line in question. The design of such telecommunication equipment has to incorporate such technical solutions and such precautions, which shall allow safe access and maintenance of both a power line and telecommunication equipment, and which shall provide protection of persons performing repairs or maintenance of the power line and/or telecommunication equipment against electric shock and protection of telecommunication equipment and attached installations against the influence of the power line (short-circuits, switching and lightning overvoltages etc.).
