High-voltage cable temperature measurement paper

High-voltage cable temperature measurement paper operates based on the thermochromic principle. When the temperature of a cable joint exceeds a set threshold, the paper undergoes reversible or irreversible color changes. It is used in power system inspections to quickly identify overheating spots in cables, preventing faults caused by poor contact.
Selection
When selecting, ensure the temperature response range covers the operating temperature of the cable, and the color change contrast should be clear and easily identifiable. Consider the impact of humidity and oil contamination in the usage environment, and industrial-grade products must possess anti-interference characteristics. The attachment method should accommodate the curved structure of the cable, and outdoor models require weather-resistant protection.
