Station post insulators are the preferred insulator by designers, manufacturers, and packagers of power substations and switchyards for Utility and Industrial environments. Substations are relied on to provide power to literally millions of people so downtime must be avoided.
For applications where seismic requirements apply, Meister International also offers high-strength and extra high-strength station post insulators.
Typically station post insulators are installed in the vertical position but they can also be used horizontally. Note though that when using them in horizontal applications, the working load strength must be de-rated for 50% of the net weight of the unit. In other words, if you have a station post rated at 2,500 lbs. cantilever, the maximum recommended working load is 1,000 lbs.
Maintenance of station post insulators is really not required as the glaze coating on the exterior of the insulator keeps dirt and pollutants from adhering to the insulator. The metal fittings on the ends of the station post insulators is hot-dipped galvanized steel that will not deteriorate.
The design of station post insulators takes into account both the mechanical and electrical requirements of IEEE, IEC, NEMA and ANSI Standards. Testing is also performed in accordance with the applicable industry standards.
While it does take time and energy to manufacture porcelain station post insulators, Meister International helps customers avoid long leadtimes by stocking industry standard station post insulators for quick delivery.
