Product Definition

Glass insulators an insulator made of tempered glass. Its surface is in the state of compression prestress, such as crack and electrical breakdown, glass insulator will break into small pieces, commonly known as “self-explosion”. This feature eliminates the need for “zero value” detection of glass insulators during operation.
The glass insulator is the crystallization of the combination of glass and insulator. Because of the characteristics of glass compared with electric porcelain, glass insulators have better stability in electrical and mechanical characteristics, and their transparency makes it easy to check the damage during operation, so that the regular electrified preventive test for insulators is cancelled. The electrical strength of glass generally remains the same throughout its operation, and its aging process is much slower than that of porcelain. Therefore, glass insulators are mainly abandoned due to self-damage, which occurs within the first year of operation, whereas the defects of porcelain insulators begin to be discovered only after several years of operation.

This standard specifies the general technical requirements, selection principles, inspection rules, acceptance, packaging and transportation, installation and operational maintenance, and operational performance testing for ac overhead line insulators with nominal voltages above 1000V.

This standard is applicable to disk-type suspended porcelain and glass insulators (insulators for short) used in ac overhead power lines, power plants and substations with nominal voltage above 1000Y and frequency 50Hz. The altitude of the installation site must be lower than 1000m, and the ambient temperature must range from -40 ° c to +40 ° c. 2 Normative reference files
