PSD-70E Double Shed Toughened Glass Insulator 146//280/450 : A Comprehensive Guide
The
PSD-70E(146/280/450 Double shell two winged) Double Shed Toughened Glass Insulator is a high-performance electrical insulator designed for reliability and durability in demanding environments. Engineered for high-voltage transmission and distribution systems, this insulator combines advanced materials and innovative design to ensure optimal performance. Below, we explore its features, benefits, technical specifications, and applications, making it a top choice for modern power infrastructure.
Key Features of the PSD-70E Insulator
Toughened Glass Construction:
Made from chemically tempered glass, the PSD-70E offers exceptional mechanical strength (70kN mechanical load rating) and resistance to thermal shock, corrosion, and UV degradation.
Shatters into harmless granular pieces upon failure, enhancing safety and simplifying inspections.
Double Shed Design:
Two strategically placed sheds increase creepage distance, reducing the risk of electrical arcing and flashovers in polluted, humid, or coastal environments.
Optimized for performance in extreme weather, including heavy rain, ice, or salt-laden atmospheres.
Zero Maintenance:
Unlike ceramic or
composite insulators, toughened glass does not degrade over time. Its non-porous surface resists dirt accumulation, ensuring consistent insulation properties without cleaning.
Environmental Resistance:
Withstands temperature ranges from -40°C to +80°C, making it suitable for global deployment.
Immune to chemical corrosion from industrial pollutants or saline environments.
Eco-Friendly:
Fully recyclable, contributing to sustainable energy infrastructure.
