Detailed Product Description：	1000 characters JTW-LD3-type line fire detector cable 1. By the thermal cable, junction boxes, terminal components; 2. Sensitive element is a special cable, referred to as thermal cable, cable package with thermal insulation from the two elastic steel wire, general wire and sheathing components with a tight collar; 3. When a certain part of their protection or temperature rises to a point in the rated operating temperature of the thermistor cables, the two wire insulation state has changed and an alarm signal; 4. Project cost, easy installation and flexible, and protection of objects can be directly contacted its protection from the long, wide; 5. From the time of the alarm detector proper, stable and reliable operating temperature; 6. The cable can be long-term use of water under forest conditions, and has good acid, alkali, oil and corrosion resistance, can be applied to dust, smoke, corrosive gas, strong electromagnetic interference, wind speed, air humidity and other harsh environments. JTW-LD3-type switch cable-type line thermal fire detector cable I level II level III level of cable resistance 0.25 ~ 0.35Ω / m Rated operating temperature (± 10%).
