We are finishing our journey through our insulator RTV silicone coated glass story by presenting the under coating alternative.
Our technical assistance team is available to help you to choose the best solution for your application.
In the meantime, to clearly understand the difference between the two technologies we are presenting the under coating option and its benefits in this article.
Benefits of glass insulators with silicone under coating
Silicone coated toughened glass insulators
- Hydrophobicity assured in the protected creepage distance
- No washing – No flashover due to pollution
- Glass insulators long-term reliability
Additional characteristics of under coating
- Insulator strings less sensitive to damage during installation
- Handling like regular glass units
- Pollution flashover voltage higher than naked glass insulators and similar to fully coated insulators
- Same packaging as regular glass insulators
When to use Fully coated vs under coated units?
Insulator strings in very heavy (IEC) pollution classes will generally require fully coated insulators, while under coated insulators are suitable for Medium and Heavy pollution areas (IEC)
Under coating, for most cases, offers an optimized solution since it ensures a performance close to a fully coated insulator, with the benefit of packing and handling conditions similar to non-coated insulators.
Under Coated insulators: benefits in packaging and handling
Similar packaging as naked glass insulators
