With the first Lapp RG® insulator installation dating back to the 1970s, no other manufacturer matches our level of experience. RG® insulators are designed to prevent contamination-related flashovers. Each insulator, produced at our LeRoy, NY factory, undergoes rigorous 100% testing and can be traced by individual serial number, ensuring unparalleled reliability and performance.
Proven Technology
No other manufacturer comes close to Lapp’s semiconductive glaze experience. Our LeRoy facility has been refining the RG® manufacturing process and rigorously testing this technology for over 50 years with evolving technological improvements.
Lapp’s RG® Resume:
- Over 1,000,000 LeRoy Produced RG® Insulators in service
- First to provide serialized tracking for each semiconductive glaze insulator we produce
- Not a one size fits all solution, we have specific glaze formulations optimized for each RG® insulator design
- Third party testing per IEC 60507 showed Lapp’s RG® TR-287 insulator to greatly outperform other technologies under extreme salt conditions:
- Standard Glaze equivalent station post
- Standard Glaze equivalent high leakage station post
- Other claimed semi-conductive offering
Applications
Lapp’s RG® Insulators were designed to eliminate the need for washing and greatly reduce the risk of contamination related flashovers. Even in areas where contaminants form thick deposits on the insulator surface, our RG® technology will prevent dry band arcing and insulator flashover. Common application areas for these products include:
Coastal Regions
Salt fog and sea salt
Industrial Areas
Coal plants, power generation facilities, cooling towers
Agricultural Areas
Agricultural contaminants, Machinery exhaust
Roadways
Heavily traveled areas, roadway salt
Benefits
The benefits of RG® Insulators are a result of the semi-conducting glaze that is baked onto the porcelain body, becoming an integral and permanent part of the insulator. RG® is available on our station posts, line posts, struts, apparatus porcelain, and long rod insulators.
RG® has more benefits than shown here. For additional information please reference the downloadable materials below or contact your local representative.
