Zinc oxide surge arresters are a significant advancement in overvoltage protection technology. Their superior performance, lightweight design, and maintenance-free operation make them the preferred choice for modern electrical systems, including 36kV distribution lines. By effectively clamping overvoltages and dissipating surge energy, they ensure the reliability and longevity of electrical infrastructure.
1. Ratings:0.22~500KV (porcelain),0.22~220KV(composite)
Zinc oxide surge arresters must comply with international standards to ensure safe and reliable operation. Key standards include:
IEC 60099-4: International standard for metal-oxide surge arresters without gaps.
IEEE C62.11: IEEE standard for metal-oxide surge arresters for AC power circuits.
ANSI/NEMA LA 1: American National Standard for surge arresters.
System Voltage: The arrester is designed for a 36kV distribution system. It must operate continuously at the system's normal operating voltage.
Rated Voltage: The rated voltage of the arrester should match or exceed the system's maximum continuous operating voltage (MCOV).
Temporary Overvoltages: The arrester should withstand temporary overvoltages (e.g., during faults or switching) without damage.
Leakage Current:
Under normal operating conditions, the arrester allows only a very small leakage current (microamps or milliamps) due to the high resistance of the zinc oxide material.
Surge Current Handling:
The arrester must be capable of discharging high surge currents (e.g., from lightning strikes or switching surges) without degradation.
Typical surge current ratings range from 5kA to 20kA or higher, depending on the application.
Energy Absorption:
The arrester must absorb and dissipate the energy from overvoltage events without failure. This is measured in kilojoules (kJ).
Temperature Range:
Zinc oxide surge arresters typically operate in a wide temperature range, from -40°C to +60°C or higher, depending on the design and housing material.
Extreme temperatures can affect the performance and lifespan of the arrester.
Pollution and Contamination:
The arrester must withstand pollution levels in the installation environment (e.g., industrial areas, coastal regions with salt spray).
Polymer-housed arresters are particularly resistant to pollution and contamination.
Humidity and Moisture:
The arrester must be sealed to prevent moisture ingress, which can degrade its performance.
UV Radiation:
For outdoor installations, the arrester must be resistant to UV radiation, which can degrade polymer housing over time.
Altitude:
The arrester should operate effectively at the installation altitude. High-altitude installations may require derating due to reduced air density.

Rated Voltage: Must match the system voltage (e.g., 36kV for your application).
Energy Absorption Capacity: Ensure the arrester can handle the expected surge energy.
Environmental Conditions: Choose polymer-housed arresters for polluted or coastal areas.
Standards Compliance: Ensure the arrester meets relevant standards (e.g., IEC 60099-4, IEEE C62.11).
| Feature | Zinc Oxide Surge Arrester | Traditional Surge Arrester |
|---|---|---|
| Spark Gap | No spark gap | Requires a spark gap for operation |
| Response Time | Extremely fast (nanoseconds) | Slower due to spark gap ionization |
| Leakage Current | Very low (microamps or milliamps) | Higher leakage current |
| Energy Absorption | High energy absorption capacity | Limited energy absorption capacity |
| Weight | Lightweight (polymer housing) | Heavier (porcelain housing) |
| Pollution Resistance | Excellent (polymer housing resists pollution) | Less resistant to pollution |
| Maintenance | Maintenance-free | Requires periodic maintenance |
Use wooden boxes and plastic packaging to protect the products from physical damage, moisture, and environmental pollutants.
