NGK line post insulator

Structure of a NGK line post insulator consists mainly of an FRP Core, a Silicone Rubber Housing and Metal End Fittings. In many cases, Composite line post insulator horizontal is mounted to a supporting structure (wooden or steel pole, tower, etc.) through an additional base.

Structure of a NGK line post insulator that is one main of composite insulators
The FRP Core is the internal insulating member designed to ensure the mechanical characteristics. The Silicone Rubber

Housing is the external insulation, which provides the necessary leakage distance and protects the core from the weather.

Metal End Fittings are assembled to the both ends of the core for the purpose of transmitting mechanical loads to the core. A base adapts the end fitting for mounting to a supporting structure.
