Classification and Development Trends of Insulating Materials
2025-09-24
Insulating materials are categorized into three main types based on their physical form: gases (such as SF₆ and C4F7N), liquids (like transformer oil), and solids (including XLPE, epoxy resin, and mica). These materials are classified under heat resistance grades ranging from Y to 250. Current trends in the industry include the use of environmentally friendly alternative gases, the application of high-performance composite materials, and nanotechnology-based modifications—all aimed at enhancing insulation strength, improving resistance to aging, and boosting eco-friendly properties.
