Foreword
GB/T 34130 "Power Bus System" is divided into the following parts.
--- Part 1. General requirements;
--- Part 21. Particular requirements for power bus systems for wall and ceiling installations;
--- Part 22. Particular requirements for power bus systems for ground and underground installations.
This part is the 21st part of GB/T 34130.
This part is drafted in accordance with the rules given in GB/T 1.1-2009.
This section uses the redrafting method to modify the use of IEC 61534-21.2014 "Power Busbar System Part 21. for walls and ceilings
Special requirements for board-mounted power busbar systems.
The technical differences between this part and IEC 61534-21.2014 and their reasons are as follows.
---About the normative reference documents, this part has made technical adjustments to adapt to China's technical conditions, adjustments
The situation is reflected in Chapter 2, “Regulatory Citations”, and the specific adjustments are as follows.
● Use GB/T 34130.1-2017 power bus system part 1 general requirements (IEC 61534-1.2014,
MOD) replaces IEC 61534-1.2011.
This section has made the following editorial changes.
--- Removed notes from IEC 61534-21.2014 that apply to other countries and regions, such as the note to 14.2.102;
--- Because China has not adopted the standard IEC 61534-21.2006, so the Appendix AA has been deleted. PT has been complied with IEC 61534-21.2006.
