The optical fiber is made of quartz glass and is packaged in various packages to form optical cables with various characteristics. The optical cable of the optical fiber temperature measuring host is not only the signal transmission medium, but also the temperature sensing element. Considering the harsh environment of the site, the temperature detection cable should have good anti-biting and anti-seismic characteristics. Therefore, the linear optical fiber temperature detector should have a strong sheath to provide good protective characteristics, but at the same time, the temperature detection cable should also provide good temperature conductivity to ensure rapid fire detection.

Features:

1. Wireless temperature sensor double armored tube protection, high tensile, compressive, flexible and strong, wiring is very simple;

2.Kevlar aramid wire low density, high strength, good toughness, high temperature resistance, easy processing and molding, is due to the "Kevlar" material tough and wear-resistant, rigid and flexible, with a knife can not enter the special ability, in the military is called "armored guard".

3. Stainless steel spiral hose: enhance mechanical and environmental characteristics, keep the overall soft, flexible, easy to connect after the cable, while avoiding interference from mice and other animals;

4. Stainless steel braided wire: enhance the cable resistance to longitudinal tension and torque.

5. Low smoke halogen-free flame retardant sheath with non-delayed combustion, combustion does not release toxic gas and smoke and other environmental protection characteristics;

6. Small outer diameter, simple structure, fast thermal penetration, short temperature response time;

7. The outer sheath adopts red low-smoke halogen free, good electrical insulation performance;

8. Corning fiber, OVD process to ensure the quality of optical fiber, to ensure the accuracy of optical fiber detection;

9. Excellent heat conduction characteristics, mechanical properties, waterproof properties, rat-bite and corrosion resistance.

   Cable trenches (including cable tunnels) are dedicated passages for laying various cables. Increased impedance at cable joints, cable overload, aging of the insulation skin, or partial discharge in the cable itself cause the cable surface to heat up, making the cable sheath and protective layer burn, accompanied by the generation of heat and flammable gases. As the temperature rises further, smoke forms and the situation develops into a fire. Once a fire breaks out, it is difficult to detect and extinguish in time, resulting in serious losses. In distributed fiber optic temperature sensing, a sinusoidal laying method is adopted: when the temperature-sensing optical fiber and temperature-sensing cable are installed on cable fixing brackets or racks, they are laid in a sine-wave pattern over the protective sheath of all monitored power or control cables, preferably in surface contact. Detectors related to the fiber Bragg grating temperature sensor should be fixed with mounting clamps during installation to prevent equipment damage caused by stress on the detector.
