Lightning strikes and switching surges are ever-present threats to electrical infrastructure, capable of causing catastrophic damage, prolonged downtime, and significant financial losses. Our advanced Lighting Arresters provide an indispensable line of defense, safeguarding your critical electrical assets, ensuring operational continuity, and extending equipment lifespan.
Product Overview
Designed for superior surge protection across a wide range of applications, our lighting arresters are engineered with cutting-edge Metal Oxide Varistor (MOV) technology. They are precisely calibrated to divert dangerous overvoltage impulses to the ground, maintaining a stable operating environment for your valuable equipment and personnel.
Key Features
Gapless Metal Oxide Varistor (MOV) Technology: Utilizes high-performance zinc oxide (ZnO) varistors, offering superior non-linear current-voltage characteristics for rapid response and reliable protection without a series gap.
High Energy Absorption Capability: Engineered to withstand and dissipate extreme surge energies from direct or indirect lightning strikes and switching transients.
Rapid Response Time: Instantly reacts to overvoltage conditions, clamping voltage levels to a safe threshold within nanoseconds.
Low Residual Voltage (Protective Level): Ensures that the voltage across the protected equipment remains below its insulation withstand level during a surge event.
Exceptional Durability & Longevity:
Robust Housing: Available in high-quality silicone rubber (polymer) for superior hydrophobicity, pollution resistance, light weight, and anti-explosion properties, or high-grade porcelain for mechanical strength and traditional applications.
UV and Weather Resistant: Designed to withstand harsh environmental conditions, including extreme temperatures, UV radiation, and corrosive atmospheres.
Explosion-Proof Design: Polymer-housed arresters are intrinsically explosion-proof, enhancing safety.
Self-Restoring Insulation: After diverting a surge, the arrester quickly returns to its high-impedance state, restoring normal system operation without interruption or component degradation.
Versatile Mounting Options: Designed for easy installation in various configurations (e.g., line-to-ground, line-to-line, pole-mounted, substation structure-mounted).
Compliance with International Standards: Fully compliant with IEC 60099-4, IEEE C62.11, ANSI, and other relevant industry standards, ensuring reliable and tested performance.
Optional Monitoring: Available with surge counters and leakage current monitors for predictive maintenance and performance tracking.
Benefits
Maximized Equipment Lifespan: Protects transformers, switchgear, generators, cables, and other critical assets from insulation breakdown and costly damage.
Enhanced System Reliability: Prevents unscheduled outages and minimizes downtime, ensuring continuous power supply and operational efficiency.
Reduced Maintenance Costs: Significantly lowers repair and replacement expenses associated with surge-damaged equipment.
Improved Safety: Safeguards personnel and prevents arc flashes or fires caused by severe overvoltage conditions.
Cost-Effective Investment: Offers long-term savings through asset protection and operational continuity, quickly outweighing the initial investment.
Adaptability: Suitable for diverse power system designs and voltage levels, offering a tailored solution for your specific needs.
