Product Description
The 11kV Polymer Lightning Arrester is designed to protect medium-voltage electrical systems from lightning strikes and switching overvoltages. It provides reliable surge protection by safely diverting transient overvoltages to ground, minimizing the risk of damage to transformers, switchgear, overhead distribution lines, and other power system equipment.
Manufactured using high-quality Metal Oxide Varistor (MOV) technology with a weather-resistant silicone polymer housing, the arrester offers excellent insulation performance, high energy absorption capability, and long service life in harsh outdoor environments.
Ideal for utility substations, distribution networks, industrial power systems, renewable energy installations, and electrical infrastructure projects.
