Insulator cleaning, insulator coating and flashover protection specialists.

USM's two step process of cleaning and silicone coating helps prevent flashovers without interrupting service.
Step #1	USM cleans insulators by gently blasting with a very soft, finely powdered limestone compound. This eliminates the need for outages and will not damage the insulator's glazing. The light dust film is non-toxic and is safely blown away with high-pressure dry air. No mess is left in the substation yard.
Step #2	For longer term flashover protection, USM coats the insulators with a specially-formulated dielectric silicone grease or silicone elastomer coating. Protective silicone coatings greatly reduce the frequency of cleaning.
