Brief Analysis of the Summary and Selection of Burning Behavior of Cables
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.
