Station post insulator

Station post insulator is used similarly to most of composite insulators and porcelain insulators consisting of weathersheds, housing and insulator end fittings.

Station post insulator

Polymer station post insulator is designed in cylindrical solid insulating core of fiberglass reinforce which provides mechanical load. The core is protected by outer silicone rubber housing. Polymer Station post insulator can be used for substations, switchgear and electrical apparatus.

Porcelain Station post insulator is designed solid core, which inner is full of cement or other materials, also called solid core insulator and consisting of one or more porcelain units and metal fittings.

The advantages of porcelain Station post insulator
◆ long service time
◆ high mechanical strength
◆ hydrophobic resistance
◆ natural material
◆ not ease to be destroyed by animals

The advantages of polymer Station post insulator have light weight, good transportation and installation, excellent pollution resistance and leakage current control due to hydrophobicity.
