Overhead electrical lines exceeding AC 1 kV - Part 2-12: National Normative Aspects (NNA) for ICELAND (based on EN 50341-1:2012)

1.1 General 1.1 IS.1 Application to new lines (snc) This Part 2-12 is only applicable to new overhead transmission lines exceeding 1 kV (AC). If deviations and/or extensions to existing transmission lines are planned, the Icelandic NC shall be informed and will decide case by case whether ÍST EN 50341 is applicable or not.

Nadzemni električni vodi za izmenične napetosti nad 1 kV - 2-12. del: Nacionalna normativna določila (NNA) za Islandijo (na podlagi EN 50341-1:2012)

1.1 Splošno
1.1 IS.1 Uporaba za nove vode
(snc) Ta del 2-12 se uporablja samo za nove nadzemne daljnovode, ki presegajo 1 kV (izmenične napetosti). Če so načrtovana odstopanja in/ali podaljšanje obstoječih daljnovodov, je treba obvestiti islandski NC, ki za vsak primer posebej določi, ali se uporabi standard ÍST EN 50341.
