Product Description

56-3 Pin Type Insulator 33kv Porcelain Insulator

 

The design of the porcelain insulators distributed by Suntec Power 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,Suntech Power 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.
