1 Solid Core Station Post Insulator PORCELAIN INSULATORS It is an insulator of generally columnar shape, and it consists of one post insulator unit or an assembly of such units and is intended to give rigid support to a live part which is insulated from earth or from another live part. Solid-core station post insulator may be manufactured according to IEC, ANSI, BS and other standards, with cantilever from 4kN to 18kN, which is used on 15kV to 750kV station and substation. There are two types for this series, normal type and anti-pollution type.
