Environmental Challenges Facing Pre-insulated Bushings

The performance requirements for pre insulated sleeve are extremely stringent in various home appliance applications. For example, the long-term high temperatures of electric kettles (100°C boiling water and steam), the strong winds and high temperatures of hair dryers (above 180°C), and the humid environments of yogurt makers (40°C and high humidity) require pre insulated junction sleeve to be heat-resistant, age-resistant, and moisture-resistant. In other words, high-quality insulated joint sleeve must possess these characteristics, including high-temperature resistance, ageing resistance, moisture resistance, and stable insulation performance, to meet the safety and reliability requirements of the home appliance industry during long-term operation.
