Polymer Housing Metal Oxide Surge Arrester

Yueqing Guoen Electric Co., Ltd. specializes in manufacturing high - quality lightning arresters that play a crucial role in protecting electrical systems.
Our lightning arresters are designed with advanced technology. They utilize zinc oxide elements, which have excellent non - linear volt - ampere characteristics. Under normal working voltage, the current flowing through the arrester is extremely small (in the microampere or milliampere range), ensuring minimal impact on the normal operation of the electrical system. When an over - voltage occurs, the resistance of the zinc oxide elements drops sharply, effectively discharging the over - voltage energy and safeguarding electrical equipment from potential damage.
The product has several outstanding features. It has a compact structure, which not only saves space but also makes installation more convenient. The overall molding process ensures good sealing performance, enhancing its anti - explosion and anti - moisture capabilities. With a large creepage distance and excellent water - repellent properties, our lightning arresters have strong pollution - resistance, reducing the need for frequent maintenance and ensuring stable operation in various environments.
Moreover, the zinc oxide resistor chips in our arresters are made with a unique formula, providing high capacity and low leakage. The actual - equipped DC reference voltage, square - wave current - carrying capacity, and high - current tolerance all exceed national standards, offering reliable protection for power grids, substations, and a wide range of electrical devices. Whether it is to protect against lightning - induced over - voltages, operation - related over - voltages, or power - frequency transient over - voltages, our lightning arresters from Yueqing Guoen Electric Co., Ltd. are your optimal choice.
