Fire Resisting Cable

Fire Resisting Cables

Fire Resistant RS 485 Databus Cables

APPLICATION

The cables are designed for RS 485 data connections where continued functionality is required during a fire

situation. This cable combines low capacitance insulation with one of the highest levels of screening to provide

high speed, interference free, data transmission where continued functionality is required during a fire situation.
