Fire wire and cable series will be introduced through standard, use occasions, produce name, type and use, Flame-retardant performance and Fire resistance level technical requirements.
Fire wire and cable standard:
Electrical performance products, like ordinary wire and cable, flame retardant, fire resistance in line with national standards GB/T18380-2001 (1EC60332: 1993), GB/T12666-1990 or national public safety industry standard GA306-2001 the requirements.
Fire wire and cable use occasions:
For a flame retardant, fire resistance, low smoke low halogen, low smoke zero halogen fire safety requirements, which are occasions, such as large-capacity power plants, nuclear power plants, subway, high-rise buildings, lots, and so densely populated.
