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

1 Scope 1.1 General BE.1 Scope of Part 1 and Part 2-2 (ncpt) Part 1 and the present Part 2-2 are only applicable to completely new or completely replaced overhead lines between two points, A and B, as well as to new supports on new foundations with nominal voltages above AC 50 kV. (A-dev) Overhead lines or supports with nominal voltages exceeding AC 1 kV up to and including AC 50 kV are treated as a high voltage of the first category in the General Regulations of the Electrical Installations (GREI) and follow completely the GREI for their dimensioning. 1.2 Field of application (ncpt) BE.1 Application to telecommunication equipment Part 1 and this NNA apply to telecommunication equipment mounted on the new supports (e.g. dishes, antennas), particularly with respect to wind assumptions.

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

1. del in ta 2-2. del tega standarda se uporabljata samo za povsem nove ali zamenjane nadzemne vode med dvema točkama – A in B – ter za nove nosilce na novih temeljih z nazivno izmenično napetostjo nad 50 kV.
