Overhead electrical lines exceeding AC 1 kV - Part 2-23: National Normative Aspects (NNA) for SLOVAKIA (based on EN 50341-1:2012)

General SK.1 New overhead line As a 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 as 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 SK.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. SK.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.).

Nadzemni električni vodi za izmenične napetosti nad 1 kV - 2-23. del: Nacionalna normativna določila (NNA) za Slovaško (na podlagi EN 50341-1:2012)

Splošno
(ncpt) SK.1 Novi nadzemni vod
Kot novi nadzemni vod se obravnava povsem nov nadzemni električni vod z nazivno napetostjo, ki med točko A in B presega 1 kV pri izmeničnem toku.
Novi odcepni vod obstoječega nadzemnega voda je treba obravnavati kot nov nadzemni vod, z izjemo podpore za spoj, za katero je treba v projektni specifikaciji določiti specifične zahteve.
Obseg uporabe tega standarda glede obnavljanja, ponovne napeljave in podaljševanja obstoječih nadzemnih vodov je treba določiti v projektni specifikaciji. Poleg tega je v projektni specifikaciji treba določiti, katere od prejšnjih nacionalnih standardov je treba uporabljati in v kolikšnem obsegu jih je treba uporabljati za zadevni projekt.
1.2 Področje uporabe
(ncpt) SK.1 Področje uporabe
Zahteve tega standarda je treba sprejeti, če je to primerno (npr. zahteve za obremenitve, zunanje razdalje itd.), tudi za telekomunikacijske kable.
V primeru nadzemnega voda, ki je v fazi načrtovanja, se morajo zadevne stranke dogovoriti o obsegu uporabe tega standarda.
Nadzemni vod v fazi izgradnje je lahko dokončan v skladu s standardi, ki se uporabljajo med fazo načrtovanja voda. Zadevne stranke se morajo dogovoriti o kakršni koli možni uporabi določenih točk tega standarda.
(ncpt) SK.2 Montaža telekomunikacijske opreme na nosilce
Določila tega standarda veljajo tudi za telekomunikacijsko opremo in naprave (antene, antenski krožniki itd.), ki so montirane na posamezne nosilce nadzemnih električnih vodov, zlasti glede obremenitev vetra in ledu na tako montirani opremi. Pri obliki in montaži je treba upoštevati zahteve omrežja, na katerega je priključen zadevni vod. Oblika takšne telekomunikacijske opreme mora vključevati tehnične rešitve in previdnostne ukrepe, ki omogočajo varen dostop do električnega voda in telekomunikacijske opreme in njihovo vzdrževanje ter omogočajo zaščito pred električnim udarom za osebe, ki izvajajo popravila ali vzdrževanje električnega voda in/ali telekomunikacijske opreme, ter zaščito telekomunikacijske opreme in pritrjenih elementov pred vplivi električnega voda (kratki stiki, stikalne in atmosferske prenapetosti
itd.).
