摘要
通过对比GB/T 19666-2019《阻燃和耐火电线电缆或光缆通则》与GB 31247-2014《电缆及光缆燃烧性能分级》,梳理两种标准下电缆各项燃烧性能的内在联系,并结合GB 51348-2019《民用建筑电气设计标准》中的要求,将此前参考GB/T 19666-2019 标准体系进行线缆选择的规范中的相关场合进行整理,归纳各类场合下对应GB 31247-2014 标准体系对线缆燃烧性能的要求,以及对消防用电设备线缆耐火性能等级的要求,并以表格形式罗列,以便应用于设计实践中.
Abstract
Through the comparison between General Rules for Flame Retardant and Fire Resistant Electric Wires and Cables or Optical Fiber Cables(GB/T 19666-2019)and Classification for Burning Behavior of Electric and Optical Cables(GB 31247-2014),the internal relations between two standards in terms of burning behavior of cables are sorted out and summarized.According to the Standard for Electrical Design of Civil Buildings(GB 51348-2019),the related situations for cable selection specified in the previous standard system GB/T 19666-2019 are sorted out,and the requirements of standard system GB 31247-2014 for burning behavior of cables and for fire resistance grade of cables used for fire-fighting electric equipment in various situations are summarized and listed in a form,in order to apply them to design practice.
