1.1 General
(ncpt) CZ.1 Definition of new overhead lines New overhead lines are defined as entirely new electrical overhead lines with a nominal voltage exceeding AC 1 kV between points A and B.
A new branch from an existing overhead line shall be considered a new line, with the exception of the branch support, for which the specific requirements shall be defined in the Project Specification.
For reconstructions, modernizations, upratings, rerouting and extensions of existing lines, the field of application of this standard shall be defined in the Project Specification. The Project Specification shall also specify which of the previous national standards are to be applied in the project and to what extent.
1.2 Field of application
(ncpt) CZ.1 Field of application
The requirements of this standard shall also be applied to telecommunication cables wherever feasible (e.g. load requirements).
For overhead lines in the design phase, the field of application of this standard shall be agreed upon by the involved parties.
Overhead lines under construction may be completed in accordance with the standards valid at the time of their design. Any potential application of specific provisions of this standard shall be agreed upon by the involved parties.
(ncpt) CZ.2 Mounting of telecommunication equipment on supports
The provisions of this standard shall also apply to telecommunication equipment (e.g. antennas, satellite dishes) installed on individual line supports, particularly with regard to wind and ice loads acting on such components.
The design and installation shall comply with the requirements of the line owner. During the design phase of such telecommunication equipment, appropriate technical solutions and protective measures shall be implemented to ensure safe access and maintenance of both the power line and the telecommunication equipment. These measures shall ensure the protection of personnel performing repairs or maintenance on either the power line or the telecommunication equipment against electric shock, as well as the protection of the telecommunication equipment and associated installations from adverse effects of the power line (e.g. short circuits, switching and lightning overvoltages).
