Safeguard your critical electrical infrastructure, equipment, and personnel from the devastating effects of lightning strikes with our advanced High-Performance Lightning Arresters. Engineered for superior reliability and durability, our arresters provide robust surge protection, ensuring operational continuity and extending the lifespan of your valuable assets.
The Threat of Lightning
Lightning is a powerful natural phenomenon capable of generating transient overvoltages of hundreds of thousands of volts and currents of tens of thousands of amperes. Without adequate protection, these surges can cause catastrophic damage, leading to:
System Downtime: Resulting in significant financial losses, production halts, and service interruptions.
Safety Hazards: Risking injury or fatality to personnel due to electrical shock or fires.
Increased Maintenance Costs: Requiring expensive repairs and replacements.
Our Lightning Arresters are your first line of defense, diverting these dangerous overvoltages safely to the ground, and restoring your system to normal operation in milliseconds.
Key Features & Advantages
1. Superior Surge Protection
Ultra-Fast Response Time: Activates in nanoseconds to clamp transient overvoltages, protecting connected equipment from damage.
High Discharge Capacity: Designed to withstand and safely dissipate extremely high lightning impulse currents (up to 200kA), preventing arrester failure during severe strikes.
Low Residual Voltage (Protective Level): Minimizes the voltage stress across protected equipment, ensuring that sensitive components are not exposed to damaging voltage levels.
2. Robust & Durable Construction
Advanced Polymer or Porcelain Housing: Available in both highly robust, track-resistant silicone rubber polymer or traditional, highly reliable ceramic porcelain, offering excellent insulation and resistance to environmental degradation.
Weather-Resistant Design: Engineered to perform flawlessly in extreme conditions, including high humidity, UV radiation, pollution, ice, and salt spray.
High-Energy Metal Oxide Varistors (MOV): Utilizes premium quality MOVs with excellent non-linear voltage-current characteristics, providing superior energy absorption and surge handling capabilities.
Uniform Voltage Distribution: Optimized design ensures even current and thermal distribution across varistor blocks, enhancing reliability and lifespan.
4. Versatile Applications
Wide Voltage Range: Available for a broad spectrum of voltage classes, from low voltage distribution systems (1kV) to extra-high voltage transmission networks (up to 800kV).
Multiple Configurations: Offered in various mounting options (e.g., cross-arm, pedestal, suspension) and designs (e.g., station class, intermediate class, distribution class) to suit specific installation requirements.
5. Compliance & Reliability
International Standards Compliant: Manufactured and tested in accordance with leading international standards, including IEC 60099-4 and ANSI C62.11, guaranteeing performance and safety.
Maintenance-Free Operation: Designed for long-term, reliable service with virtually no maintenance required after installation, minimizing operational costs.
