Low-Voltage Zinc Oxide Arrester (Model: HY1.5W-0.28/1.3)
Core Function
This device is a surge protection component for low-voltage power systems, designed to safeguard electrical equipment from damage caused by lightning surges and transient overvoltages.
Key Working Principles
Normal Operation: It exhibits extremely high resistance, acting as an insulator and not interfering with regular power supply.
Overvoltage Event: When abnormal overvoltage (e.g., lightning strikes, switching surges) occurs, its resistance drops instantly, quickly discharging the excess energy to the ground. This clamps the voltage to a safe level, protecting connected equipment.
Automatic Recovery: After the overvoltage is eliminated, it automatically returns to its high-resistance state, restoring normal system operation without manual reset.
Product Advantages
Seamless Integration: Compact design for easy installation in low-voltage distribution boxes and systems.
High Pressure Resistance: Capable of withstanding high instantaneous surge currents without failure.
Anti-pollution & Anti-corrosion: Resistant to environmental contaminants and corrosion, suitable for outdoor and harsh industrial environments.
Sun-proof & Anti-aging: Weather-resistant materials ensure long-term stability and performance under UV exposure.
Insulation & Flame Retardant: Excellent insulation properties and flame-retardant casing enhance operational safety.
Multiple Specifications: Available in various models to meet different low-voltage application requirements.
Typical Applications
Low-voltage power distribution systems (0.22kV / 0.4kV)
Building electrical panels and terminal electrical equipment
Communication base stations and weak current systems
Low-voltage side protection for renewable energy systems (photovoltaic, wind power)
