Factors driving the move away from porcelain insulators
- Porcelain insulators can shatter and pose safety risks to personnel and the grid
- Limited resilience in polluted and extreme environments
- High maintenance and inspection costs
- Brittle structure, heavy load, and high transportation costs
- Flashovers triggering widespread blackouts and equipment damage
What’s driving the change?
The shift to Composite Insulators
Unmatched safety
Composite insulators are designed to ensure high safety, even in failure scenarios. Unlike porcelain, they do not shatter explosively. Instead, they delaminate or puncture in the event of an internal fault or external impact.
Maintenance-free operation
No need for regular cleaning and inspections, resulting in a lower total cost of ownership.
Superior pollution resistance
Hydrophobic surface ensures effective leakage current control and superior flashover resistance. Optimized insulation design for high creepage performance with minimal deformation, even in extended insulator lengths.
Proven Global Performance
Trusted across the globe, operating reliably in harsh climates, polluted zones, and seismic regions.
Handling and flexibility
Composite insulators are significantly lighter, reducing transport costs, structural load, and ensuring extreme safety during installation. They also offer flexibility to meet varied design and application requirements.
