Looking for a reliable, long-lasting solution for high-voltage insulation? Our toughened glass insulators are designed for superior performance in transmission lines and substation applications from 35kV up to 1000kV. Manufactured from high-quality tempered glass, these insulators deliver excellent mechanical strength, electrical reliability, and self-cleaning performance—even in harsh weather or highly polluted environments.

✅ Key Advantages of Our Glass Insulators:

  • Self-breaking detection: Damaged units shatter visibly, making inspections faster and safer.
  • No aging or UV degradation: Unlike polymer insulators, glass remains stable for decades.
  • High dielectric strength: Prevents flashover even under heavy contamination.
  • Strong hydrophobicity: Smooth surface resists dirt, dust, and salt build-up.
  • Extreme climate resilience: Ideal for coastal, desert, and high-altitude conditions.

⚙️ Applications:

  • Overhead power transmission lines (35kV–1000kV)
  • High-voltage substations
  • Coastal, industrial, and desert zones with high pollution levels
  • Replacement of aged porcelain or composite insulators

Our glass insulators are widely exported and trusted by utilities worldwide for their long service life, low maintenance cost, and dependable performance.

Glass insulators are primarily used in electrical power transmission and distribution systems to support and separate electrical conductors without allowing current to flow through them. They are commonly found on utility poles, transmission towers, and substations.

Glass Suspension Insulators – Made of toughened glass, offering high mechanical strength and self-healing properties (shattering upon failure). Porcelain Suspension Insulators – Traditional and widely used, with high mechanical and electrical strength.
Polymer (Composite) Suspension Insulators – Made of a fiberglass core with a polymer (silicone rubber) housing, providing lightweight, hydrophobic, and pollution-resistant benefits.

Of course, we also provide composite insulators and related hardware. If you need, you can visit this interface.
