Porcelain A20 Insulators

Meister International supplies the highest-quality porcelain A20 bus insulators. Porcelain A20 bus insulators are used by switchgear, power transformer and bus duct manufacturers where reliability and ‘uptime’ is paramount. Porcelain A20 bus insulators typically have high mechanical stresses placed on them, and our A20 bus insulators meet all industry standards.

Manufacturers, packagers, and distributors of switchgear, power transformers, generators and bus-duct consistently choose porcelain insulators over epoxy and silicone designs due to their durability. If you have ever experienced downtime due to a field failure of an ‘epoxy insulator’, the outrageously high cost of downtime could have been avoided by using porcelain insulators. Utility engineers and consultants continue to specify porcelain insulators for their key switchyard projects because of their superior reliability.

The design of the porcelain insulators distributed by Meister International comply with the mechanical and electrical requirements of IEEE, IEC, NEMA and ANSI Standards. Testing is also performed in accordance with the applicable industry standards. Custom porcelain insulators can also designed and manufactured for customer specific applications and requirements.

Maintenance of porcelain insulators is really not required as the glaze coating on the exterior of the insulator keeps dirt and pollutants from adhering to the porcelain insulator. The metal fittings used in the manufacture of the porcelain insulators distributed by Meister International are made from metals that will not deteriorate and are ideal for supporting copper and aluminum busbars.

While the manufacturing of porcelain insulators does take time, Meister International helps customers avoid long lead times by stocking industry standard porcelain insulators. Stocking agreements are offered so that your production process can run without interruption. We put our customers first and always work to exceed our customers’ expectations.
