AC Disc Suspension Porcelain Insulator (Normal Type)
Standard profile (XP Series) porcelain insulators designed for high-voltage transmission lines in clean and light pollution areas. Meets IEC standards with mechanical failing loads ranging from 40kN to 530kN.
Ideal for Standard Environments
The Normal Type disc suspension insulator is the workhorse of high-voltage transmission lines in areas with low pollution levels. Unlike the Anti-Pollution type, it features a standard shed profile that balances mechanical strength, electrical performance, and cost-effectiveness.
Wide Range of Mechanical Classes
Vuulcan offers a comprehensive range from 40kN (U40B) for distribution lines up to 530kN (U530B) for UHV transmission lines.
- Standard Type: Optimized for typical overhead line requirements.
- Large Creepage Option: Some models offer extended creepage distance for enhanced safety margins.
- Reliability: Manufactured using high-strength aluminous porcelain (C-130) for long-term durability.
