Introduction

Gas discharge tube arresters (GDT) are devices that are used to protect electrical equipment from power surges caused by lightning, static electricity, or power outages. They are most commonly used to protect telephone lines, coaxial and power lines, and appliances. GDTs work by limiting the surge voltage that is applied to the equipment. GDTs are composed of two electrodes, a gas discharge tube, and a protective coating. This article will discuss the 2035-42-SM application field and working principle of GDTs.

Application Field

The 2035-42-SM is a type of gas discharge tube arrester. It is most commonly used in low-voltage power distribution systems and is designed to protect against transient surges generated by lightning or other sources. It is used to protect sensitive equipment, such as electronics, from power surges, while still allowing for normal operation. It can be found in residential, commercial, and industrial settings.The 2035-42-SM is a fixed gas discharge tube arrester that is designed for use in environments where the nominal line voltage is between 75V and 1000V. Its maximum continuous operating temperature is 145°C, with a maximum allowable voltage of 130V. It has a surge capacity of 8 kA (kiloamperes) and a protection level of 0.2 kA (Data current).

Working Principle

The working principle of the 2035-42-SM gas discharge tube arrester is based on the principle of a spark gap. When a large surge of electrical current passes through the arrester, a spark is produced between the two electrodes. This spark ionizes the gas inside of the tube, which temporarily reduces the voltage of the surge before it reaches the protected device. The spark is produced when a voltage difference of more than the breakdown voltage of the gas discharge tube is applied between the two electrodes. This voltage is usually much less than the peak of the surge. The ionized gas acts as a resistor, limiting the voltage that is applied to the protected device. Once the surge is gone, the tube automatically resets and is ready to protect against the next surge.

Conclusion

The 2035-42-SM gas discharge tube arrester provides a reliable, economical, and efficient way to protect electric equipment from transient surges. The device works by limiting the surge voltage that reaches the protected device. It is designed for use in residential, commercial, and industrial settings, and has a maximum continuous operating temperature of 145°C. The device is easy to install and is a cost-effective way to protect valuable equipment and data from power surges.
