YH10WZ-204/532 220 kV Power Station Type Zinc Oxide Surge Arrester
Product Overview
The YH10WZ-204/532 Zinc Oxide Surge Arrester is designed for 220 kV power systems, providing reliable overvoltage protection to ensure the safe and stable operation of electrical equipment. It is ideal for substations, transmission lines, and high-voltage power infrastructure, offering long-term, stable protection against overvoltage incidents.
Core Technology & Performance Advantages
1. Internal Core Components
The arrester utilizes zinc-oxide resistor valves as its core element, which effectively limit overvoltage amplitudes and absorb overvoltage energy. This reduces the risk of damage to power equipment and provides a robust protective barrier for the electrical grid.
2. Manufacturing Quality Control
Every step of production is strictly controlled, from component selection and processing to final inspection. The arrester is manufactured using molded composite technology with a fully sealed design without air gaps, ensuring excellent pollution resistance and suitability for complex outdoor environments.
3. Structural Design Highlights
Detachable Terminal Bolts: Simple and reliable connection for easy installation and maintenance.
Hot-Dip Galvanized Base: Provides long-term rust resistance, strong coating durability, and easy removal for maintenance, ensuring stable operation over time.
