Description

Advanced High-Performance Lightning Arrester

Protect your critical electrical infrastructure from the devastating effects of lightning strikes and transient overvoltages with our state-of-the-art Lightning Arresters. Engineered for superior performance, reliability, and longevity, our arresters provide an unparalleled defense, ensuring operational continuity, preventing costly equipment damage, and enhancing safety across various applications.

Overview

Lightning and switching surges are inevitable threats to power systems and sensitive electronic equipment. Our Lightning Arresters are precision-designed to divert these high-energy impulses safely to the ground, limiting the overvoltage to a safe level for the connected apparatus. Utilizing the latest Metal Oxide Varistor (MOV) technology, our gapless designs offer rapid response, high energy absorption capability, and exceptional durability, making them the ultimate guardian for your investments.

Key Features & Benefits

• Unparalleled Surge Protection: Employs advanced Metal Oxide Varistor (MOV) technology for non-linear, rapid response to overvoltages, providing superior protection against both lightning and switching surges.
• Gapless Design: Ensures instant response without the need for series gaps, leading to lower residual voltages and enhanced protective margins for your equipment.
• High Energy Absorption Capability: Designed to withstand and dissipate multiple high-energy impulses, ensuring long-term reliability even in highly exposed environments.
• Robust & Weatherproof Construction: Available with hydrophobic silicone rubber or high-strength porcelain housings, offering excellent resistance to pollution, UV radiation, moisture, and extreme temperatures, ensuring a long service life.
• Low Residual Voltage (Protective Level): Minimizes the voltage stress on protected equipment, safeguarding insulation and extending equipment lifespan.
• Exceptional Durability & Longevity: Manufactured with high-quality materials and stringent quality control, guaranteeing minimal degradation over time and reduced maintenance requirements.
• Standards Compliance: Fully compliant with international standards such as IEC 60099-4 and IEEE C62.11, ensuring certified performance and reliability.
• Flexible Installation: Designed for easy and versatile mounting in various configurations, including substation, line, and apparatus protection.
• Enhanced Safety: Reduces the risk of electrical fires, equipment explosions, and danger to personnel, promoting a safer operating environment.

How It Works

Our Lightning Arrester acts as a voltage-dependent resistor. Under normal operating conditions (system voltage), it presents a very high impedance, effectively acting as an insulator, allowing no current flow to ground.

When an overvoltage surge (from lightning or switching) occurs, the arrester's internal Metal Oxide Varistor (MOV) blocks become instantly and highly conductive. This creates a low-impedance path, diverting the surge current safely to the earth. Once the overvoltage surge has passed and the system voltage returns to normal, the MOV blocks rapidly revert to their high-impedance, non-conductive state, restoring the system to normal operation without interrupting power.

Applications

Our Lightning Arresters are ideal for comprehensive protection across a wide range of critical electrical systems:

• Power Transmission & Distribution Substations: Protecting transformers, circuit breakers, busbars, and switchgear.
• Overhead Transmission Lines: Safeguarding line insulation and preventing flashovers.
• Industrial Facilities & Factories: Protecting motors, control systems, and sensitive machinery.
• Telecommunication Towers & Base Stations: Essential for protecting communication equipment from direct and induced lightning effects.
• Renewable Energy Installations: Critical for solar farms (inverters, string boxes) and wind turbines (generators, control systems).
• Railway Systems: Protecting traction substations and signaling equipment.
• Oil & Gas Facilities: Ensuring the reliability of critical control systems and pumping stations in hazardous environments.
• Commercial & Residential Buildings: For robust main service entrance protection.
