Sep 30,2024
Electrical performance: The main electrical performance of insulators is flashover characteristics. In order to avoid breakdown in operation, the breakdown voltage of the insulator is higher than the flashover voltage. Insulators of different voltage levels have different withstand voltage requirements.
The basic properties of insulators include electrical properties, mechanical properties and thermal properties.
Electrical performance: The main electrical performance of insulators is flashover characteristics. In order to avoid breakdown in operation, the breakdown voltage of the insulator is higher than the flashover voltage. Insulators of different voltage levels have different withstand voltage requirements.
Mechanical properties: insulators are often subjected to various mechanical forces in operation, such as the gravity and tension of the wire, wind, and ice weight. Therefore, the insulator needs to have good mechanical strength to withstand these forces.
Thermal performance: outdoor insulators require the ability to withstand temperature changes. For example, porcelain insulators require several hot and cold cycles without cracking.
In addition, the insulator should also have certain environmental resistance and aging resistance to maintain its stability in harsh weather conditions.
