Flame Retardant Cable Class B1 is mainly suitable for rated voltage 450/750V and below Power plants, small power tools, instrumentation, power lighting lines, and other applications.
It can be widely used in places with relatively dense populations and high flame retardant combustion levels requirements, such as subways, airports, hospitals, super high-rise buildings, large shopping malls, hotels, museums, exhibition centers, and transportation hubs, and other places.
