ПСД-70Е (PSD-70E) glass suspension insulator is specifically designed for use in areas with high levels of atmospheric pollution, such as coastal regions, mining zones, and industrial areas. With an extended creepage distance, it serves as an upgraded replacement for standard profile glass insulators like the ПС-70Е (PS-70E), which are intended for normal pollution conditions.
ПСД-70Е (PSD-70E) glass suspension insulator provides both mechanical support and electrical insulation for high-voltage transmission and distribution lines. When used in suspension strings, the insulators are assembled in series and secured using either V-clips or W-clips, depending on the specific application or customer preference.
Currently, the main markets for the ПСД-70Е (PSD-70E) glass suspension insulator are Russia, Ukraine, and countries in Central Asia.
The ПСД-70Е (PSD-70E) is manufactured in compliance with IEC standards, ensuring both mechanical strength and long-term reliability. It offers a minimum mechanical failing load of 70kN, a shed diameter of 280mm, and is available in two height options: 127mm and 146mm. The creepage distance is 411mm, making it suitable for polluted environments where high insulation performance is essential.
