Key Features of Double shell PSD-70E 146//280/450 glass insulators

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.


Technical Specifications：
Model: PSD-70E
Mechanical Load Capacity: 70 kN (15,700 lbs)
Creepage Distance: ≥320 mm (varies by design)
Standards Compliance: IEC 60383, ANSI C29.2, and other international certifications.
Weight: ~8–10 kg (lightweight compared to ceramic equivalents).
Advantages Over Ceramic and Composite Insulators
Visibility: Transparent glass allows easy visual inspection for cracks or damage.
Longevity: No aging or surface erosion, ensuring a service life exceeding 50 years.
Cost-Effective: Reduced maintenance and replacement costs over time.


Applications：
The PSD-70E is ideal for:
High-Voltage Transmission Lines (up to 765 kV)
Railway Electrification Systems
Substations and Switchyards
Polluted or Coastal Areas where salt fog or industrial contaminants are present.
