Ultimate Protection: High-Performance Metal Oxide (MOV) Lightning Arrester
Protect your vital electrical infrastructure from the devastating effects of lightning strikes and transient overvoltages with our advanced Metal Oxide Varistor (MOV) Lightning Arresters. Engineered for superior performance, reliability, and longevity, our arresters ensure continuous operation, minimize downtime, and safeguard your valuable assets against costly damage.
What is a Lightning Arrester?
A lightning arrester is a critical safety device designed to protect electrical systems, equipment, and components from dangerous high-voltage surges caused by lightning strikes or switching operations. It acts as a bypass route for these surges, safely diverting the excessive current to the ground, and then quickly returning to an insulating state once the overvoltage passes, allowing normal system operation to resume without interruption.
Key Features & Benefits
Our lightning arresters are built with cutting-edge technology and robust materials to deliver unparalleled protection:
Superior Overvoltage Protection: Utilizes highly non-linear Metal Oxide Varistor (MOV) blocks that provide excellent protection against atmospheric and switching overvoltages.
High Energy Absorption Capacity: Engineered to withstand and dissipate significant impulse currents, ensuring complete protection even during severe lightning events.
Low Residual Voltage: Limits the voltage across protected equipment to a safe level, significantly reducing the risk of insulation breakdown and equipment failure.
Rapid Response Time: Activates in nanoseconds to shunt surge currents, providing instantaneous protection to sensitive equipment.
Robust & Weatherproof Design: Available with high-quality polymer (silicone rubber) or porcelain housings, offering superior insulation, UV resistance, anti-pollution, and resistance to harsh environmental conditions.
Maintenance-Free Operation: Designed for a long service life with no internal degradation under normal operating conditions, eliminating the need for periodic maintenance.
Explosion-Proof (Polymer Type): Our polymer-housed arresters often feature explosion-proof characteristics, enhancing safety for personnel and surrounding equipment.
Compliance with International Standards: Fully compliant with relevant international standards such as IEC 60099-4 and ANSI C62.11, ensuring certified performance and reliability.
Wide Operating Temperature Range: Designed to perform reliably across a broad spectrum of ambient temperatures, from extreme cold to intense heat.
Versatile Mounting Options: Available with various mounting configurations for easy integration into existing or new substations, transmission lines, and industrial setups.
How It Works
Our MOV lightning arresters function on the principle of variable resistance:
Normal Operation: Under normal system voltage, the MOV blocks act as a high impedance, effectively insulating the system and allowing negligible leakage current.
Overvoltage Event: When a lightning strike or switching surge causes an overvoltage, the MOV's resistance instantly drops to a very low level.
Surge Diversion: This allows the dangerous surge current to be safely diverted through the arrester and into the ground, bypassing the protected equipment.
Self-Restoration: Once the overvoltage passes, the MOV blocks rapidly revert to their high-impedance state, extinguishing the follow current and restoring the system to normal operation without interruption.
Applications
Our lightning arresters are essential for a wide range of applications requiring robust overvoltage protection:
High Voltage (HV) & Medium Voltage (MV) Substations: Protecting transformers, circuit breakers, busbars, and other critical substation equipment.
Transmission & Distribution Lines: Guarding overhead power lines and associated equipment.
Industrial Facilities: Protecting motors, control systems, PLCs, and power electronics in factories, chemical plants, and mines.
Power Plants: Ensuring the reliability of generators, switchgear, and control circuits.
Renewable Energy Systems: Essential for solar farms (inverters, string boxes) and wind turbines (nacelle, tower base).
Commercial & Utility Buildings: Protecting sensitive electronic equipment, data centers, and critical infrastructure.
Railway Systems: Safeguarding traction power supply systems and signaling equipment.
Telecommunications: Protecting communication towers and equipment.
