High-Performance Polymer Lightning Arrester | Advanced Overvoltage Protection

Safeguarding Your Critical Electrical Assets from Nature's Fury

Lightning strikes are a formidable and unpredictable threat to electrical infrastructure, leading to severe equipment damage, costly downtime, and potential safety hazards. Our advanced Polymer Lightning Arrester (also known as a surge arrester or surge diverter) is engineered to provide superior overvoltage protection, channeling dangerous lightning surges safely to ground while ensuring the continuous, reliable operation of your electrical systems.

Designed for robust performance and longevity, our lightning arresters utilize cutting-edge technology and high-quality materials to protect everything from high-voltage transmission lines and substations to industrial facilities and sensitive electronic equipment.

Key Features & Technological Advantages:

• Advanced Zinc Oxide (ZnO) Varistors: At the core of our arresters are highly non-linear ZnO varistor blocks. These provide excellent current-voltage characteristics, ensuring rapid response to overvoltages, high energy absorption capability, and a low residual voltage during discharge, effectively limiting the surge impact on protected equipment.
• Gapless Design: Our modern gapless design offers continuous protection, eliminates the need for series gaps, and provides superior performance by preventing power frequency arc discharges and ensuring stable operation.
• Hydrophobic Polymer Housing: Encased in a durable, lightweight, and explosion-proof silicone rubber (or other polymer composite) housing. This material offers:
  • Superior Contamination Performance: Excellent hydrophobic properties prevent flashovers even in heavily polluted and humid environments.
  • UV Resistance: Long-term outdoor stability under harsh solar radiation.
  • Lightweight & Easy Installation: Significantly lighter than traditional porcelain housing, simplifying transport and installation.
  • Explosion-Proof: Prevents fragmentation during arrester failure, enhancing safety.
• High Energy Absorption Capability: Capable of dissipating significant amounts of surge energy, protecting equipment from direct and indirect lightning strikes and switching surges.
• Low Residual Voltage: Minimizes the voltage stress on connected equipment during a surge event, providing superior insulation coordination.
• Robust Mechanical Design: Engineered for high seismic withstand and resistance to extreme weather conditions, ensuring long-term reliability.
• Compliance with International Standards: Fully compliant with IEC 60099-4, ANSI/IEEE C62.11, and other relevant international standards, guaranteeing performance and safety.

Benefits for Your Operations:

• Enhanced System Reliability: Minimize unplanned outages and maximize uptime by protecting critical assets from overvoltage damage.
• Reduced Maintenance & Replacement Costs: Significantly extend the lifespan of transformers, switchgear, cables, and other expensive equipment, leading to substantial long-term savings.
• Superior Safety: Protect personnel and infrastructure by safely diverting dangerous lightning currents away from sensitive areas and preventing explosive failures.
• Optimal Insulation Coordination: Our arresters help maintain appropriate insulation levels throughout your system, preventing cascading failures.
• Easy & Safe Installation: Lightweight polymer design reduces installation time and risks.
• Environmentally Friendly: Polymer housing often results in a lower carbon footprint compared to traditional alternatives, and our products are free from harmful materials.

Applications:

Our Polymer Lightning Arresters are suitable for a wide range of applications across various voltage levels, including:

• High Voltage (HV) & Medium Voltage (MV) Substations: Protecting power transformers, circuit breakers, and busbars.
• Transmission & Distribution Lines: Overhead lines, cable systems, and line entrances to substations.
• Power Generation Plants: Protecting generators, switchyards, and auxiliary equipment (both conventional and renewable energy such as solar farms and wind turbines).
• Industrial Facilities: Heavy industries, manufacturing plants, chemical processing facilities, and oil & gas installations.
• Railway Electrification Systems: Protecting traction substations and overhead lines.
• Telecommunication & Data Centers: Safeguarding sensitive electronic equipment and communication infrastructure.
• Capacitor Banks & Shunt Reactors: Protecting these critical components from surge overvoltages.
