Opportunities to Further Develop Porcelain Insulator Technology in Terms of Performance, Cost & Profitability
The different properties of porcelain, composite and glass materials have caused each technology to have specific market niches related to type of application, service environment and boundary conditions. Porcelain still dominates the HV insulator marketplace in general but this position is being increasingly challenged. This places growing pressure for continued improvements in both performance and cost. Based on investigating porcelain insulator production plants over 30 years, this presentation identifies trends and proposes areas where technical as well as economic improvements still remain possible.
