What is a Surge Arrester?
A surge arrester protects electrical equipment from voltage spikes caused by lightning or switching by safely diverting excess voltage to the ground. Engineer’s enterprise provides two types of surge arrestors:
- Porcelain Surge Arresters
- Polymer Surge Arresters

Porcelain vs Polymer Surge Arrestors
| Parameter | Porcelain Surge Arrester | Polymer Surge Arrester |
|---|---|---|
|
Material & Design |
Made of rigid glazed ceramic; strong and durable with a traditional structure. |
Constructed from silicone rubber over a fiberglass core; lightweight and flexible. |
|
Installation & Handling |
Heavy and brittle; requires lifting equipment and cautious handling during transport and setup. |
Lightweight and easy to install; ideal for quick deployment with minimal equipment. |
|
Contamination Behavior |
Performs well in moderately clean environments; requires cleaning in high-pollution or humid conditions. |
Excellent resistance to pollution and moisture due to hydrophobic surface. |
|
Maintenance & Lifespan |
Long service life if maintained regularly; periodic surface cleaning is essential in polluted settings. |
Low maintenance with long-term reliability in harsh and remote environments. |
|
When to Choose |
Best for installations in clean, stable environments where traditional equipment is already in place. |
Preferred for polluted, coastal, remote, or compact areas where low weight, safety, and reduced maintenance are key. |
