Overhead electrical lines exceeding AC 1 kV-National Normative Aspects (NNA) for ESTONIA (based on EN 50341-1:2012) 超过交流1 kV的架空电线
发布日期: 2019-01-25
BS EN 50341-2-20:2018适用于所有具有标称系统电压的新架空电线 超过交流1 kV,也适用于低压(交流1 kV以下)架空线路 通过空中电缆。结构设计的要求也适用于DC 项目规范中给出了电气要求的架空线路。交叉引用:EVS 814:2003EVS 843:2016EVS-EN 1991-1-4/NA:2007EVS 884:2017EVS-EN 1991-1-4/A1:2010/NA:2010EVS-EN 1993-3-1/NA:2009购买本文件时可用的所有当前修改件均包含在购买本文件中。
BS EN 50341-2-20:2018 applies to all new overhead electric lines with nominal system voltages exceeding AC 1 kV and also for low voltage (below 1 kV AC) overhead lines performed by aerial cables. The requirements of the structural design are applicable also for DC overhead lines, where the electrical requirements are given in the Project Specification.Cross References:EVS 814:2003EVS 843:2016EVS-EN 1991-1-4/NA:2007EVS 884:2017EVS-EN 1991-1-4/A1:2010/NA:2010EVS-EN 1993-3-1/NA:2009All current amendments available at time of purchase are included with the purchase of this document.
