HIGH VOLTAGE INSULATOR CLEANING & COATING
USM's methods of cleaning and silicone coating prevent leakage problems without interupting service.
First, we clean insulators by gently blasting with pulverized limestone. This eliminates the need to de-energize and does not damage insulator glazing.
The remaining non-toxic dust is blown away with high pressure air. Depending on the type of contamination, coating insulators with a specially-formulated dielectric silicone elastomer is an option.
Due to it's hydrophobic characteristics and ability to encapsulate contaminants, flash-overs of this nature are prevented. This option also extends the time between cleanings.
