    Mechanical properties: insulators are often subjected to the action of gravity and tension of the wire, wind force, ice weight, insulator dead weight, wire vibration, mechanical force of equipment operation, short-circuit electric force, earthquake and other mechanical forces during operation. The relevant standards have strict requirements for mechanical properties.
    Thermal performance: outdoor insulators require the ability to withstand sudden changes in temperature. Porcelain insulators, for example, require several hot and cold cycles without cracking. Due to the current passing through the insulating sleeve, the temperature rise of its parts and insulating parts and the allowable short-time current value must meet the requirements of the relevant standards.
