Gas Discharge Tube Arresters (GDT) are devices designed to protect electrical components from the damaging effects of lightning and other over-voltage surges. The CG34.5 is one of the most commonly used GDT, and is widely used in industrial, commercial, and residential applications due to its impressive performance and competitive price point. This article provides an overview of the CG34.5 application field and working principle.

The CG34.5 is a surge arrester designed for use in power distribution systems and other low-voltage equipment lines. It is available in two different versions, with an operating voltage of either 6 kV or 8.7 kV. The CG34.5 has a nominal discharge current rating of 10 kA, making it ideal for applications where the occurrence of lightning or other transient over-voltage occurs. The CG34.5 is UL-listed for use in Outdoor Rated devices, meaning it can be used in outdoor environments. The device is also suitable for use in environments with a high level of dirt, dust, and other debris.

The protection mechanism used in the CG34.5 is gas-filled technology, which consists of an internal arrangement of metal electrodes and a dielectric gas. When the surge voltage exceeds the breakdown voltage of the gas, it causes a rapid current flow between the electrodes, resulting in the discharge of electrical energy in the form of heat and light. The internal electrodes and the surrounding gas cool quickly, allowing the arrester to reset and restore protection in less than a second. This is what enables the CG34.5 to protect electrical equipment from lightning and other transient surges.

The CG34.5 also features a high level of surge current protection. It has a fast response time, and can protect equipment from a surge current of up to 15 kA. The arrester has a highly reliable design that helps to reduce fault current and reduce the risk of disruption or equipment damage in the event of a surge. The CG34.5 also features a built-in current limiter, which helps to protect connected equipment against current overload.

The CG34.5 is also designed for easy installation. The device features a compact housing, enabling it to be mounted on a variety of surfaces. The arrester is also equipped with universal mounting holes, making it compatible with a wide range of mounting systems. The CG34.5 also features a built-in fault indicator, which helps to indicate when the arrester needs to be serviced.

In conclusion, the CG34.5 is a Gas Discharge Tube Arresters (GDT) designed for use in outdoor and indoor power distribution systems and other low-voltage equipment lines. It features a fast response time and can protect equipment from surge currents of up to 15 kA. The arrester is equipped with a highly reliable design that helps to reduce fault current and protect connected equipment from damage. It is also designed for easy installation, with a universal mounting system and a built-in current limiter.
