Fire Detection Armored FO Sensing Cable is a sensor cable of DTS (distributed temperature sensing system). This kind of cable is strengthened by SUS spring tube and SUS braiding and has very good mechanical performance of tensile resistance and pressure resistance. The cable is widely used in tunnel、building、oil and chemical factory area.
