New generation of insulator coating
Dow Corning Corp., USA, a global leader in silicon-based technology and innovation, has introduced its Sylgard® brand high-voltage insulator coating plus (HVIC+), a new generation of high-voltage insulator coating that will offer protections against power distribution interruptions due to arcing and flashover from salt spray, industrial pollutants, and even desert sand. Sylgard HVIC+ improves on the original RTV coating to provide the best combination of wet electrical performance, tracking resistance, and durability that will assure utility engineers years of reliable operation. Improvements in the wet product also make application easier and faster, reducing labour cost and downtime.
The new Sylgard HVIC+ offers long-term water repellency/hydrophobicity. This is invaluable to high-voltage applications because without it contaminants on the surface of the insulators become wet and produce a conductive layer, which contributes to an increase in leakage currents, dryband arcing, and ultimately flashover. The new coating also offers resistance to atmospheric and chemical degradation (the coated insulators remain unaffected by salt air, airborne pollutants, rain or humidity). Sylgard HVIC+ also exhibits high-tracking resistance to reduce damage during salt storms or other severe contamination events. It can be used in applications including: glass, porcelain and composite insulators where improved surface dielectric properties are needed, line and station insulators, as well as bushings, instrument transformers and related devices, as well as other applications requiring arc resistance. 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.
For more than 50 years, Dow Corning has provided the electrical industry with a complete range of silicone-based materials, including high-voltage insulator coatings, silicone rubber for composite insulators, cable enhancement fluids, resins and varnishes, and high-performance transformer fluids. In addition to high-quality, innovative products, Dow Corning’s total solutions offering includes global manufacturing, distribution, and customer service resources to tailor solutions to meet customer needs exactly.
