FIELD: electricity.
SUBSTANCE: invention relates to electric engineering and relates to support, pin and suspended polymer insulators for high-voltage substations and power transmission lines. Proposed polymer insulator comprises the following: electric insulated bearing body, metal reinforcement and control element made of tempered electrotechnical glass. Control element is damaged in process of operation with reduction of electric insulated properties of bearing body.
EFFECT: increased reliability of power supply due to high fitness of insulators for monitoring of internal condition in process of operation.
