Porcelain Station Post Insulators

 

eister International offers porcelain station post insulators with standard strength, high-strength, and extra high-strength ratings. Stock is maintained in many sizes that are standard in the electric power industry. Porcelain station post insulators’ low maintenance operation and superior electrical and mechanical characteristics make them the ideal choice of porcelain station post insulators for high voltage switch and substation bus support applications. These porcelain station post insulators are installed worldwide and have years of proven reliability.

Meister International maintains an extensive stock of industry-standard porcelain station post insulators that are available for next-day shipping. This helps customers avoid long lead times.   Porcelain station post insulators are available in various electrical and mechanical ratings to allow engineers to specify the proper insulator for their installation.

Strength Ratings:

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 usually installed in the vertical position, but they can also be used horizontally. Note 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.

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.

Purchase station post insulators from Meister International with confidence. You’ll be assured a quality product, quick shipping and quantity discounts.
