Product Description

U240B Tempered Glass Insulator

High-performance Insulation for Overhead Transmission Lines
 

Product Description

The U240B is a high-voltage tempered glass insulator designed for reliable electrical insulation and mechanical support in overhead power transmission and distribution networks. Engineered with precision, it ensures long-term performance in harsh environmental conditions, including extreme temperatures, pollution, and humidity.

Key Features

• Material: High-strength tempered glass with exceptional dielectric properties, resistant to UV radiation, chemical corrosion, and thermal shock.
• Design: Streamlined shed profile for optimized pollution resistance and self-cleaning capability.
• Mechanical Strength: Rated mechanical failing load (MFL) of 240 kN, ensuring durability under high tension.
• Electrical Performance:
  • Power frequency wet withstand voltage:   ≥ 70 kV 
  • Lightning impulse withstand voltage:   ≥ 170 kV
• Anti-Fog Design: Multi-shed configuration prevents flashover in humid or contaminated environments.
• Zero Maintenance: Tempered glass is impervious to aging, eliminating the need for periodic hydrophobicity tests.
• Eco-Friendly: Fully recyclable and free of hazardous materials (RoHS compliant).

Application

• Overhead transmission lines (69 kV to 500 kV systems).
• Substations, switchgear, and railway electrification.
• Coastal, industrial, or high-pollution areas.
