Application of Thermal Camera – Testing of Cable Encapsulating

To ensure stable production and consistent product quality in cable manufacturing, an industrial thermal camera is installed at the top of the workshop using a fixed bracket, with its lens precisely aimed at critical high-temperature zones—specifically above the preheating and vertical curing furnaces. This setup enables comprehensive monitoring of the entire cable encapsulation process, covering all essential equipment and temperature-sensitive areas on the production line.

Accurate Monitoring of Furnace Temperatures

The thermal camera continuously measures the temperatures of the preheating and vertical furnaces, ensuring the rubber insulation material reaches and maintains a fully molten state throughout the process. Proper melting is essential for the rubber to flow and bond correctly to the cable core, ensuring a uniform and secure insulation layer.

Real-Time Surface Temperature Detection
In addition to furnace monitoring, the system captures the surface temperature of the cable in real time as it moves along the production line. This allows operators to track the thermal condition of the rubber layer—both on the surface and within the molten material—with high accuracy. Any temperature anomalies or uneven heating can be detected early, helping to prevent defects in the encapsulation quality.

Enhanced Process Visibility and Quality Control

Integrating thermal imaging technology gives manufacturers a powerful tool for real-time process visibility and precise thermal management. Early issue detection reduces scrap rates, improves process parameters, and ensures consistent product quality. This results in higher reliability and performance of the final cable products, meeting strict industry standards for insulation and safety.
