Caledonian Flame Retardant RS485 Databus Cables

Transcription

1 Flame Retardant RS485 Databus Cables Copper Wire Braid(optional) Individual AL/Polyester Tape(optional) Foam PE/Foam skin PE. Stranded Tinned Copper AL/Polyester Tape With Tinned Copper Drain Wire PVC Outer APPLICATION The cables are designed for RS485 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.
