Solid core station post insulators can be divided into porcelain post insulator and porcelain station post insulator used for substations, electrical equipment and electrical devices.

According to insulator material, Solid core station post insulators can be divided into
◆ Polymer insulators made by silicone rubber
◆ Porcelain station post insulator made by ceramic material

According to insulator usage, Solid core station post insulators can be divided into
◆ Substation insulator
◆ Apparatus insulator

According to insulator voltage, Solid core station post insulators are normally divided into
◆ High voltage post insulator: such as 500kv post insulators
◆ Extra high voltage post insulators: such as 1150kv post insulator
◆ Medium voltage post insulator: 66kv to 132kv
◆ Low voltage post insulator: upto 36kv

Solid core station post insulators are used station or substations and are manufactured from non-porous electrical polymer and tested as per ANSI, IEEE, IEC and AS standards etc.
