CG34.0

Today, there is a wide range of applications for gas discharge tube arresters or GDTs. In this article, we\'ll discuss the application field of the CG34.0 gas discharge tube and its working principle. Let\'s start by discussing what a GDT is and why it\'s used in so many different applications.

A gas discharge tube (GDT) is an electronic device that is used to limit the amount of voltage and current that flows in an electric circuit. GDTs contain a small amount of high-pressure gas and two electrodes, which provide a path for a spark to flow if the voltage exceeds a given amount. GDTs are used to protect electrical equipment from overvoltage or transient surges in electricity supply. They are used extensively in telecommunications, industrial, and consumer electronics applications.

The CG34.0 is an air-insulated type 2 surge arrester commonly used to protect transmission lines from direct and indirect lightning strikes and other high voltage transients. It is designed to work in the range of 80kA peak current. The CG34.0 has two stage-avalanche devices, which are triggered sequentially when triggered, allowing for a high speed response time to ensure complete protection against dangerous voltage surges.

The CG34.0 has several advantages compared to other types of GDTs. It is designed with a high voltage factor protection and robust surge withstand capability, and it has a high capacitance, allowing it to absorb larger surges in the event of a lightning strike or power surge. Additionally, it has lower temperature dependence, allowing it to be used in extreme temperatures.

The working principle of the CG34.0 is based on a combination of series and parallel avalanche triggering technologies, which are connected to a single dielectric structure. When voltage is applied to the dielectric, electrons flow between the electrodes, creating an electric arc. This initiates the pair of internal high voltage stages, creating a protective shield that limits the flow of current through the arc path and has a reset action that eliminates arc marks after a surge event.

The CG34.0 gas discharge tube is a versatile and reliable device that protects electrical systems from the damaging effects of voltage surges and other transient events. Its combination of series and parallel avalanche technologies allow for quick response times to dangerous voltage levels, ensuring complete protection against power surges and lightning strikes. It is used extensively in industries and electronic systems, and is a cost-effective way to safeguard equipment from voltage overload.
