Description
Our High Voltage Composite Surge Arrester is a high-performance overvoltage protection device designed for power transmission and distribution systems. It effectively suppresses lightning overvoltages and switching overvoltages, safeguarding transformers, circuit breakers, and other key electrical equipment from damage.
Core Features
- Advanced Zinc Oxide Varistor: Utilizes high-quality zinc oxide resistors with excellent nonlinear volt-ampere characteristics, fast response to steep waves, and high current-carrying capacity.
- Composite Insulation Housing: Integral molded silicone rubber housing offers superior hydrophobicity, pollution resistance, explosion-proof performance, and long-term aging resistance.
- Lightweight & Compact: Significantly lighter than traditional porcelain arresters, reducing installation and transportation costs while maintaining high mechanical strength.
- Reliable Sealing: Two-end encapsulation process ensures excellent moisture resistance and long-term operational stability in harsh environments.
- Easy Installation: Compact structure and standardized interface design enable quick and simple mounting.
Applications
Ideal for AC systems up to 220kV, including power plants, substations, overhead transmission lines, and distribution networks, especially in high-pollution, high-altitude, or seismic zones.
Technical Highlights
- Low residual voltage for effective protection.
- High energy absorption capability.
- Long service life with minimal maintenance.
- Compliant with international standards (IEC, GB).
This arrester combines superior electrical performance, mechanical reliability, and environmental adaptability, making it an essential component for modern power systems.
