10 kV Zinc Oxide Surge Arrester from China Suppliers - High-Quality Protection for Electrical Equipment from Factory
Product Overview
The 10 kV zinc oxide arrester (model 17/50) is a core protective device designed to shield various electrical systems from overvoltage damage. As a professional overvoltage protector, it plays a crucial role in ensuring the service life and operational reliability of key electrical equipment such as transformers, switches, capacitors, and motors. Its core function is to mitigate the risks posed by atmospheric overvoltage (e.g., caused by lightning strikes), operating overvoltage, and power frequency transient overvoltage (resulting from power system operational anomalies). By participating in the insulation coordination of electrical systems, this arrester effectively maintains the integrity and stable operation of power systems, railway electrification systems, and communication networks.
Product Performance
