Insulator Cleaning

ESM, Inc., can safely clean insulators while “ENERGIZED” or “DE-ENERGIZED” by use of our proper cleaning procedures. However, we specialize in “ENERGIZED” cleaning of porcelain and polymer insulators. Insulators in service are subject to surface dirt to some degree, in all operating areas. Several types of contaminates can affect insulators performance. Proper maintenance procedures must be strictly followed to prevent damage to equipment.

HV Insulator Coating

ESM, Inc., recommends the application of an insulator coating product to areas where high contamination and/or corrosion will occur to prevent leakage current and flashover to all porcelain insulators.

The following coating products are recommended:

– HV Silicone Grease Compound
– HV RTV Products
– HV CSL Products 
– HV Sylgard (Dow Corning)
