针对现行在照明配电设计中末端照明分支回路导体截面普遍选择过大的问题,综合各个有关规范标准,从导体选择的各个方面进行分析,提出在绝大多数情况下,将末端照明配电分支回路绝缘铜导体截面从2.5mm2改为1.5mm2,可以节约大量的铜材,是符合节能减排原则的举措,利国利民,应引起重视。 Aiming at the current problem that the cross-section of the branch circuit of the terminal lighting branch is too large in the lighting power distribution design, the author analyzes all aspects of the conductor selection based on the relevant standards, and proposes that in most cases, Loop insulated copper conductor cross section from 2.5mm2 to 1.5mm2, can save a lot of copper, is in line with the principle of energy-saving emission reduction initiatives, the benefit the country, should be taken seriously.
