Applications
Suspension insulators are designed for power transmission and distribution overhead lines, particularly for extreme high voltage transmission applications where they provide superior performance compared to other insulator types.
Key Advantages
- Outstanding crack resistance and low thermal expansion coefficient
- Convenient transportation and flexible installation options
- Reasonable insulation structure with high reliability of interturn insulation
- Low OSS and temperature rise with high mechanical strength
- Strong weather resistance and stainless steel flange construction
- Low magnetic inductivity, high resistivity, compact size and lightweight design
