Spiral Pipe Armored Temperature Sensing Cable
Spiral pipe armored sensing cable is general sensor cable of DTS(distributed temperature sensing system). This kind of cable is strengthened by both SUS spring tube and SUS braiding and has very good mechanical performance of tensile resistance and pressure resistance. The cable is widely used in fire detecting, building health detecting, temperature detecting, etc.
Cable Structure

|
Package 1 |
Package 2 |
Package 1: usually for indoor cable, light weight cables.
Package 2: usually for outdoor cable, heavy weight cables
Usually for each roll, the cable length is 2km, but we could provide customized package for different cable lengths. |
Mark
Usually we only attach Test Report on the out package of the cable, but we could also mark as your requirements, such as:
1. Company Name
2. Cross /Net weight
3. Drum No: XX
4. Cable Length : XX
