Porcelain Disc Insulator

 

 

Porcelain disc insulators are typically used in power transmission line. Porcelain is the most commonly used insulating material until now. Not only any voltage but also any contamination level can be done by changing number of insulators. TCI porcelain disc insulators have been one of best choice for world’s transmission projects.

Porcelain disc insulator with RTV coating type

Pollution is becoming more and more serious in many areas. So disc insulators with RTV coating are increasingly popular. It has unique characteristics:

• Resistance to tracking and erosion

• Resistance to weathering & UV

• Resistance to chemical & physical degradation by water

• Volume resistivity

• Resistance to corona & ozone

• Application onto glass or porcelain surfaces, especially when done in the field

 

 

Note: ANSI 52-1, 52-2, 52-3, 52-4, 52-5,52-8 and 52-10 are available too.

Glaze color: grey, brown
