Safeguard your critical infrastructure and sensitive electrical equipment from the destructive power of lightning strikes and transient overvoltages with the GuardianShield™ High-Performance Lightning Arrester. Engineered for superior reliability and long-term performance, our lightning arresters are an indispensable component for any robust electrical protection scheme.
Using advanced Metal Oxide Varistor (MOV) technology, the GuardianShield™ Arrester provides a virtually instantaneous, low-impedance path to ground for dangerous overvoltages, while simultaneously blocking the normal system operating voltage. This critical action prevents damage to valuable assets, minimizes downtime, and ensures the continuous, safe operation of your electrical systems.
Key Features:
Advanced MOV Technology: Utilizes high-quality, non-linear zinc oxide varistor blocks to deliver exceptional energy absorption capability and a fast response time.
High Surge Current Withstand: Designed to safely divert extreme lightning current impulses, protecting equipment even during severe electrical storms.
Low Residual Voltage: Ensures that equipment is exposed to the lowest possible voltage during a surge, significantly reducing insulation stress and potential damage.
Fast Response Time: Activates in nanoseconds, providing immediate protection against rapidly rising voltage transients.
Robust & Durable Construction: Encapsulated in a high-grade, weather-resistant silicone polymer or porcelain housing, offering excellent hydrophobic properties, UV resistance, and resistance to environmental contaminants.
Wide Voltage Range: Available for a comprehensive spectrum of voltage classes, from low voltage distribution systems to ultra-high voltage transmission lines.
Self-Healing Capability: MOV blocks can recover from multiple surge events, ensuring sustained protection over their operational lifespan.
Compliant with International Standards: Manufactured and tested to meet or exceed IEC 60099-4, ANSI C62.11, and other relevant global standards, guaranteeing quality and performance.
Maintenance-Free Operation: Designed for reliability, requiring minimal to no maintenance once installed.
Unrivaled Benefits:
Prevent Costly Equipment Damage: Protects transformers, switchgear, generators, cables, and other vital components from catastrophic failure.
Maximize System Uptime: Avoids outages and operational disruptions caused by lightning strikes, ensuring continuous service delivery.
Enhance Operational Safety: Reduces the risk of electrical fires, equipment explosions, and hazards to personnel.
Extend Equipment Lifespan: Minimizes electrical stress on insulation, preserving the integrity and longevity of your valuable assets.
Reduce Maintenance Costs: Prevents damage that would necessitate expensive repairs, replacements, and emergency call-outs.
Ensure Grid Stability: Contributes to the overall reliability and resilience of power networks.
