Porcelain Metal-Oxide Surge Arresters

Property Specification

Type: Porcelain-Housed Metal-Oxide Surge Arrester

Features: Combining high-grade metal-oxide varistors with durable insulating construction, this surge protector is designed for power generation, transmission, and distribution networks operating between 0.22 kV and 220 kV. It delivers excellent voltage-clamping performance, high surge-current discharge capacity, and rapid response times with a flat steep-front response curve. Engineered to suppress lightning transients, switching overvoltages, and abnormal fast-front voltage surges, it provides reliable protection to prevent equipment insulation breakdown and ensure continuous system stability.
