Meister International has been supplying the industry with porcelain station post insulators since 2003. Standard strength, high-strength, and extra high-strength station post insulators are available from stock or have a very short leadtime. Porcelain station post insulators are preferred by Utilities around the world as they maintenance-free and offer superior electrical and mechanical characteristics. Porcelain Station Post insulators are the ideal choice for high voltage switches and substation bus support applications.
Meister International maintains an extensive stock of industry-standard porcelain station post insulators that are typically available for next-day shipping. This helps customers avoid long lead times.
Standard strength porcelain station post insulators are typically used in all standard high-voltage switch and bus applications. They meet or exceed all ANSI standards in both electrical and mechanical characteristics for their voltage class.
High strength porcelain station post insulators are used when an extra amount of mechanical strength is required for heavy-duty bus and switch projects. High-strength porcelain station post insulators have the same electrical ratings as the standard strength porcelain station post insulators. In applications where there are severe short circuits, high-strength porcelain station post insulators are often used. They meet or exceed all ANSI standards in both electrical and mechanical characteristics for their voltage class.
Extra-High strength porcelain station post insulators are used for projects that involve extremely heavy mechanical loads. They meet or exceed all ANSI standards in both electrical and mechanical characteristics for their voltage class.
Porcelain station post insulators are typically installed in the vertical position, but they can also be used horizontally. When installed horizontally, the working load strength of the station post insulators 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.
For over 80 years, porcelain station post insulators have been the preferred insulator by designers, manufacturers, and packagers of power substations and switchyards for utility and industrial environments. Our porcelain station post insulators’ superior operating characteristics provide the strength and long life needed for reliable substation operation. Porcelain station post insulators from Meister International provide efficient and trouble-free service for operating voltages from 7.5kv to 1100kv.
Maintenance of porcelain station post insulators is really not required because 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 our porcelain station post insulators are hot-dipped galvanized steel that will not deteriorate.
The design of our porcelain 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.
