Drop type lightning arrester
Release time:
2025-11-04
A Drop Type Lightning Arrester (also known as a Drop-Out Surge Arrester) is designed to protect electrical power systems from transient overvoltages caused by lightning strikes or switching operations.
In modern power distribution and industrial facilities, lightning and switching surges remain major threats to electrical equipment reliability. The Drop Type Lightning Arrester offers a compact, durable, and high-performance solution — engineered to ensure continuous protection, stability, and compliance with international standards such as IEC 60099-4 and IEEE C62.11.
A Drop Type Lightning Arrester (also known as a Drop-Out Surge Arrester) is designed to protect electrical power systems from transient overvoltages caused by lightning strikes or switching operations.
It combines a zinc oxide (ZnO) varistor core with an intelligent drop-out mechanism — when the arrester endures an abnormal surge current or insulation failure, it automatically drops out of service, visibly indicating isolation and ensuring system safety.
🌐 Key Features & Advantages
✅ 1. High Surge Absorption Capability
Utilizes advanced ZnO varistor technology to achieve superior non-linear voltage-current characteristics.
Withstands surge currents up to 65 kA (as per IEC test level), ensuring exceptional reliability during lightning or switching surges.
🧩 2. Visible Drop-Out Design
The unique drop type mechanism allows visual fault indication — a clear sign for maintenance teams, improving response time and system uptime.
Ideal for outdoor pole-mounted applications, reducing inspection complexity.
🛡️ 3. Enhanced Safety & Durability
The arrester body is made from silicone rubber housing, offering excellent hydrophobicity, UV resistance, and pollution resistance.
Complies with ANSI C29.13 and IEC 60099-4 standards for mechanical and thermal stability.
⚙️ 4. Easy Installation & Maintenance
Designed with standard fitting dimensions for quick installation in overhead distribution lines.
The drop-out function simplifies post-fault maintenance without interrupting other circuits.
