Product Introduction of Distributed Fiber Optic Cable Temperature Measurement System:
Why do cables need to monitor temperature？
During the operation of power cables, the conductor, strato isolante, and metal shielding layer will be damaged, causing the cable to heat up and increasing the working temperature of each part. Excessive temperature can affect the insulation performance of the insulation material, cause insulation aging, shorten the service life of the cable, and in serious cases, lead to fire and power outage accidents. Basato sul principio dell'effetto di diffusione Raman, Fuzhou Yinuo Technology has developed a technology for installing fibra ottica distribuita temperature measurement in power cables, which can achieve full monitoring of cable temperature. It has the ability to resist electromagnetic interference, continuously measure the temperature points of the fiber optic cable along each point, timely detect local temperature anomalies, analyze insulation problems of the line, and prevent cable fires, ensuring the continuous and safe operation of the cable.
Caratteristiche del sistema di misurazione della temperatura distribuito in fibra ottica
Completamente distribuito: DTS distributed fiber optic temperature measurement can detect the complete distributed temperature along the entire fiber optic line in seconds without any omissions.
Long distance monitoring: The distributed optical fiber temperature measurement system of optoelectronics can monitor a distance of up to 30KM, and can customize longer distance temperature measurements.

Temperature sensing fiber optic temperature measurement laying scheme
The laying method of temperature sensing optical fibers in cable interlayer and cable body
Temperature monitoring is required for each cable. The cable is fixed using surface mounted (esterno) cavi ottici. The laying of optical cables is fixed with optical cable fixing parts (insulation ties) to tightly bond the optical cable with the outer surface of the cable.
