A Lightning Arrester is a protective electrical device designed to safeguard power systems and equipment from lightning strikes, switching surges, and transient overvoltages. It provides a low-resistance path to ground, safely diverting excess voltage away from transformers, switchgear, transmission lines, and other critical electrical assets.Manufactured with high-quality metal oxide varistors (MOV) and polymer housing, lightning arresters offer excellent insulation, weather resistance, and long-term reliability in both indoor and outdoor installations. They help improve system stability, reduce equipment damage, minimize downtime, and extend the lifespan of electrical infrastructure.
