10KV Distribution Type Zinc Oxide Lightning Arrester

Featuring a high-performance Zinc Oxide (ZnO) core and a durable silicone rubber polymer housing, this arrester reduces lightning-induced tripping rates by 70%+ while clamping overvoltages in microseconds. Designed for easy pole-mounted or substation installation, it withstands harsh environments like coastal salt spray, industrial pollution, and extreme temperatures (-40°C to +40°C). Compliant with GB 11032-2000 (IEC 60099-4) and JB/T 10497-2005, this maintenance-free solution ensures reliable protection for: Distribution Transformers: Prevent insulation breakdown during lightning events. Rural/Urban Overhead Lines: Minimize outages in high-lightning regions. Industrial Feeders: Safeguard sensitive equipment from transient surges.
