Rising Trend: Glass Insulators in High Demand

The Rising Popularity of Glass Insulators in Modern Power Transmission

The use of glass insulators has surged in recent years, particularly in high-voltage and ultra-high voltage AC/DC overhead transmission lines. The increasing demand is attributed to several key advantages that glass insulators offer over traditional materials.

Advantages of Glass Insulators

• Mature Manufacturing Technology: Glass insulators are produced using well-established and refined manufacturing processes, ensuring quality and reliability.
• Weathering Resistance: These insulators exhibit excellent resistance to environmental factors, contributing to their longevity and durability.
• Various Load Capacities: Available in a range of mechanical and electrical damage loads, glass insulators can meet the needs of diverse transmission line requirements.

Market Growth Driven by Infrastructure Projects

In China, the acceleration of State Grid projects has significantly boosted the demand for glass insulators. The market size in China reached 0.229 billion yuan in 2022, with a notable increase in ultra-high voltage insulators. This growth reflects a global trend, with countries like France and Italy moving towards replacing traditional porcelain insulators with modern glass alternatives.

Global Adoption and Usage

By 1973, over 70 countries had adopted tempered glass insulators for their transmission lines. The global installation count surpassed 100 million pieces on 35-750 kV lines. In France, 90% of newly built lines now use tempered glass insulator strings, showcasing their widespread acceptance. By 1979, the operational count of glass insulators worldwide reached 200 million.
