Solid core line post insulators can be divided into ANSI types, GB types and other types as the related standards. These porcelain line post insulators can be white/grey/brown.

Solid core line post insulators types:
ANSI types: 57-1, 57-2, 57-3, 57-4, 57-5, 57-11, 57-12, 57-13, 57-14, 57-15, 57-21, 57-22, 57-23, 57-24, 57-25, 57-31, 57-32, 57-33, 57-34, 57-35
GB types: PS-15-300, PS-15-500
Other types: Pin Post, 20kV Line Post Insulators, 24kV Line Post Insulators
Having the porcelain insulators advantages
As a higher voltage level than pin insulators
Playing a more wide role in overhead line applications

Solid core line post insulators are used on distribution and transmission line application for high voltage power system. Solid core line post insulator can be mounted in a vertical or horizontal way, and also can be mounted on the crossarm or wooden poles.
