Power transformer temperature color labels

Temperature color labels for power transformers utilize thermochromic materials that change color in response to temperature variations. They are attached to the transformer casing to monitor operating temperatures. These labels are used to visually indicate localized overheating in equipment, preventing insulation aging failures, and are commonly employed during routine inspections of distribution equipment.
Selection
When selecting, consider the transformer's rated temperature range, and ensure the temperature measurement range of the color-changing labels covers the equipment's operating temperature. The observation distance determines the size of the color-changing labels; choose waterproof types for outdoor environments. Pay attention to the temperature resistance rating of the adhesive to match the transformer's surface material, and regularly replace any failed color-changing labels.
