When it comes to protecting electrical systems, surge arresters are an essential line of defense. A single lightning strike or switching surge can damage valuable equipment, cause costly downtime, and create safety risks. That’s why understanding the different types of surge arresters is crucial for engineers, utility companies, and industrial buyers looking for reliable protection solutions.
In this blog, we will cover the 5 main surge arrester categories, their characteristics, and how they apply in different environments. We’ll also highlight advanced protection products and accessories that ensure long-term system stability and safety.
Station class surge arresters are designed for high-voltage transmission systems and large substations. They provide maximum protection against both lightning and switching surges. These arresters are typically installed at critical points in the grid where failure could cause widespread outages.
Key Features:
High energy absorption capacity
Long service life under harsh conditions
Suitable for extra-high voltage applications
| Specification | Details |
|---|---|
| Voltage Range | 110kV and above |
| Material Type | Polymer Surge Arrester / Porcelain Lightning Arrester |
| Common Use | Substations, transmission lines |
This type of surge arrester is often used in medium-voltage networks such as industrial facilities and utility distribution systems. They balance cost and performance, offering robust protection for equipment that faces moderate surge exposure.
Advantages:
Compact and efficient design
Ideal for industrial distribution lines
Available in both polymeric lightning arrester and porcelain types
Distribution class arresters are among the most widely used, especially in urban and rural distribution networks. They protect transformers, capacitor banks, and switchgear from overvoltage conditions.
Benefits:
Flexible installation options
Available as polymer surge arresters for lightweight durability
Long-lasting resistance to environmental stress
Secondary surge arresters are designed for low-voltage systems, typically below 1kV. They are commonly used in residential, commercial, and small industrial setups to protect end-user equipment from transient surges.
Applications:
Power panels in buildings
Small industrial machines
Backup protection for sensitive devices
In addition to the standard surge arrester types, there are special application designs tailored for unique environments:
Porcelain Lightning Arresters – preferred in traditional installations where mechanical strength is critical.
Polymeric Lightning Arresters – lightweight, hydrophobic, and resistant to pollution, widely used in coastal and industrial areas.
Arc-blowing lightning protectors and resistors – specialized devices for enhanced circuit protection.
Choosing the right surge arrester is only part of a complete protection strategy. Our product portfolio covers a wide range of lightning protection products, including:
Lightning arresters and accessories
High and low voltage fuses
Circuit protection devices (arc-blowing lightning protectors, resistors, surge protectors)
