| Sylgard high voltage insulator coating Sylgard HVIC+, Dow Corning's new one-part silicone high voltage insulator coating for electrical system maintenance, provides long-term water repellency to protect against power distribution interruptions due to arcing and flashover from salt spray, industrial pollutants and desert sand. Sylgard HVIC+ offers long-term water repellency/hydrophobicity, which prevents contaminants on the surface of the insulators from becoming wet and producing a conductive layer, which contributes to an increase in leakage currents, dryband arcing, and ultimately flashover. It also is unaffected by salt air, airborne pollutants, rain and humidity. The coating can be used in line and station insulators, bushings, instrument transformers and for surface resistance on bucket truck booms. It is also useful on glass, porcelain and composite insulators where improved surface dielectric properties are needed. It is particularly well-suited for applications requiring arc resistance, such as barrier boards used in switch gear and in large motors. Sylgard HVIC+ requires only one application, eliminating the need for repeated water washing or greasing, which results in significant savings in maintenance and replacement costs. write your comments about the article :: © 2006 Construction News :: home page |
