Product Description

Product Description

Introducing the Zinc Oxide Arrester, a cutting-edge, fully sealed, and highly reliable lightning protection marvel designed specifically for 10kV power distribution systems. This innovative device is crafted from a zinc oxide valve column, upper and lower electrodes, and seamlessly molded silicone rubber, offering remarkable features:

1. Revolutionary design resolves traditional sealing issues by forming a dense integration of the arrester's core and jacket, thus eliminating internal cavities that lead to breathing. This ingenious solution is the technical breakthrough needed to prevent moisture ingress and ensure the integrity of internal components.
2. The core showcases an exceptional capacity to endure internal overvoltage, coupled with outstanding aging characteristics, guaranteeing long-lasting performance and reliability.

Engineered with a specially developed valve plate and meticulously calculated core parameters, this arrester ensures unwavering resilience against arc grounding, PT resonance, and various operational overvoltages. It is built to operate safely over long durations under line voltages, alongside enduring 2.5 to 3 times power frequency overvoltages. Impressively, it withstands voltage durations 1 to 3 magnitudes higher than international standards, ensuring unparalleled safety and reliability.

Installation

(1) Prior to installation, verify the nameplate to ensure the arrester's rated voltage matches the system voltage at the installation site;

(2) Choose between suspension or vertical installation methods. For vertical installations, note that the arrester should not serve as a load-bearing support insulator;

(3) Maintain the lead wire at an optimal length to preserve its protection effectiveness, and avoid excessive tension that could stress the arrester.

Test

• To build up operational insights, preventive tests are advisable every 4-5 years. Key testing includes measuring U1mA at the DC 1mA arrester's terminals.
• Ensure that the U1mA voltage recorded before installation is no less than 97% of its factory-set value.
• During preventive testing, U1mA voltage should not drop below 26kV.
• Note: Minimize the harmonic component of the DC power during testing. Poor waveform quality can lead to lower measured U1mA values.
• Our latest 10kV synthetic insulated zinc oxide arrester for power distribution has been thoroughly lab-tested and proven reliable over 15 months at outdoor line voltage. These tests confirm superior jacket performance, dependable arrester structure, and excellent core stability. With over 2,000 cores in operation annually, the product consistently achieves outstanding protection performance, low incident rates, and requires no maintenance throughout its service life.
