U240B High-Voltage Suspension Glass Insulator
IEC 60305-Certified Solution for 132kV Transmission Networks
Product Highlights
Industrial-Grade Durability
Engineered with toughened borosilicate glass for extreme weather resistance (-40°C to +80°C)
320mm creepage distance prevents flashover in polluted environments (Salt Deposit Density ≤0.35mg/cm²)
Fail-Safe Performance
70kN minimum failing load (MFL) with zinc-galvanized forged steel caps
100% visible fracture detection - glass shatters completely upon failure
Eco-Smart Design
Anti-aging silicone-coated green surface enhances hydrophobicity (CA≥110°)
40+ year service life with zero scheduled maintenance
Key Advantages
Superior Pollution Resistance
Passed 10,000h salt fog test (5% NaCl solution, 35°C)
≤0.02% annual degradation rate under industrial contamination
Cost-Effective Installation
Pre-assembled drop-forged yoke plates (M16/M20 optional)
Compatible with all major tower types (Lattice, Tubular, Pole)
Smart Grid Ready
Optional RFID tracking and pollution monitoring sensor integration
≤0.5µA leakage current at 132kV nominal voltage
Typical Applications
132kV Overhead Transmission Lines (Coastal/Desert/Industrial Corridors)
Substation Bus Support (Indoor/Outdoor)
HVDC Converter Stations
Renewable Energy Integration (Wind Farm Collector Systems)
Performance Data

FAQ
Q: Why choose glass over composite/polymer insulators?
A: Glass provides:
• Inherent UV resistance (no surface erosion)
• Non-aging material properties (no CCL degradation)
• Instant fault visibility (vs. hidden cracks in composite)
Q: How does the green coating enhance performance?
A: The silicone-based green coating:
Reduces dust adhesion by 40% vs. standard brown
Maintains hydrophobicity transfer up to 15 years
Meets OSHA safety color requirements
Q: What quality guarantees do you provide?
A:100% factory tested: Electro-mechanical, thermal shock
