Working Principle: The core of the temperature-sensing cable consists of one (or multiple) pair(s) of mutually insulated conductors. The insulation layer is made of a special thermosensitive material. Under normal temperatures, the conductors remain insulated from each other. When the temperature at any point along the cable rises and reaches the preset alarm threshold, the thermosensitive insulation layer at that location undergoes rapid physical or chemical changes (such as melting or a sudden change in resistance), causing the two conductors to come into direct contact and create a short circuit. The connected signal processor detects this short circuit signal, immediately identifies it as a fire or overheating hazard, and triggers a fire alarm.
 

Environmental Adaptability: Capable of withstanding high temperatures and pollution, ensuring stable operation in harsh industrial environments.

Continuous Monitoring: Functions like a "security perimeter" covering the entire high-risk area, eliminating any blind spots in protection.

Precise Localization: Accurately reports the location of abnormal temperature points, significantly reducing troubleshooting and response time.

Efficient Integration: Deeply interconnects with production equipment and firefighting facilities, enabling automated "detection-alarm-response" processes to minimize losses.

Economic Benefits: A single successful warning can prevent potential equipment damage and production shutdown losses amounting to tens of millions, offering an extremely high return on investment.

This case demonstrates that temperature-sensing cables are not merely simple alarm devices but serve as "proactive safety nerves" deeply embedded in critical industrial processes. They are indispensable technological means for ensuring the continuous and safe operation of modern industries.
