Solid core station post insulators are one main kind f solid core insulators, which can be made from porcelain and polymer materials and generally used with break switch.
If Solid core station post insulators are used with aluminum double side break switch, the application of Solid core station post insulators
◆ it can be used for line sectionalizing, by-passing circuit breakers
◆ opening magnetizing current of transformer primary connections
◆ Without arcing horns, it can be used for isolating breakers or as a disconnecting switch
The features of Solid core station post insulators
◆ High strength
◆ High conductivity aluminum made for insulator end fittings
◆ High temperature resistant
◆ Used in limit temperature rise to 30℃ over an ambient of 40℃
Solid core station post insulators can be divided into porcelain post insulator and polymer post insulator with excellent electrical and mechanical properties.
