With the implementation of Standard for electrical design of civil buildings (GB31247-2014-2019),New requirements are put forward in terms of cable corrosion,somke density,smoke toxicity,flaming droplet/particle,flame retardance,burning behavior.This paper is based on the level of cable characteristics specified in GB 51348-2019 and current electrical design codes for types of buildings,The similarities and differences are compared and analyzed.The characteristic indexes of flame retardant cables suitable for civil buildings are summarized for the reference of electrical designers.
