Gas Discharge Tube Arresters (GDT) is widely used as a protective device in locations where a surge of electrical energy such as lightning can cause enormous property damage and human losses. The CG590 Gas Discharge Tube Arrester, or GDT, is a high efficiency, low internal resistance arrester used to protect transmission and distribution systems against lightning and other transient overvoltages.

The CG590 GDT has a large current capability and an extremely low internal resistance, making it suitable for a variety of applications. These applications include power distribution systems, industrial installations, telecommunications networks, and railway systems. It can be used in both residential and commercial settings, and can also be used in offshore environments.

The main working principle of the CG590 GDT is that it acts as a surge protector. This means that in the event of a lightning strike, it will conduct the surge of electricity safely and effectively away from the protected system. This is done by limiting the voltage on the system and providing a low impedance path for the surge.

The CG590 GDT is also designed to have high surge current interruption capability. This means that it can shut down the current flow and protect the protected system from overvoltage and overcurrent events such as surges from lightning. This is achieved thanks to its two distinct laminations which are separated by a gap. The gap makes it possible for the electrical current to be switched off at the right moment and prevents any further damage to the protected system.

The CG590 GDT also features an extremely low internal resistance, which helps it to dissipate a high voltage surge quickly. This is due to the two layers of silver-coated polycarbonate which form the GDT. The silver coating provides an increased current conduction capability and helps dissipate the surplus energy without damage. In addition, the internal resistance of the GDT is also adjustable, allowing the voltage to be adjusted according to the application.

In addition to its surge protection capabilities, the CG590 GDT also features a built-in indicator circuit. This circuit provides an indication of the arrester’s condition and can provide an indication of whether or not the protected system has been damaged.

The CG590 is also able to withstand a wide temperature range and is environmentally sealed for even better protection. This allows it to be used in both indoor and outdoor environments. Furthermore, the GDT is designed to be easy to install and maintain, with minimal setup and only periodic maintenance required.

To sum up, the CG590 Gas Discharge Tube Arrester is a high efficiency, low internal resistance surge protection device that can be used in power distributions systems, industrial installations, telecommunications networks, and railway systems. It has a high current interruption capability, adjustable internal resistance, indicator circuit, and environmental sealing. All of these features make it an ideal choice for protecting against lightning strikes and other transient overvoltages.
