Porcelain post insulator


The features of Porcelain post insulator
◆ Made from C130 body for improved performance designs
◆ High mechanical strength
◆ Good insulation resistance
◆ Isostatic process for shorter lead-times
◆ Long term life

Porcelain post insulator is designed to comply with the requirements of the level of electrical insulation and mechanical strength, which also used in pollution areas.

The characteristics of Porcelain post insulator
◆ Minimum nominal creepage distance
◆ Color of glaze
◆ Lightning impulse withstand voltage, dry
◆ Power frequency withstand voltage, wet
◆ Mechanical failing load etc.

Porcelain post insulator is one of outdoor insulators, also called solid core insulator and used with external end fittings (for high voltage switchgears).
