Gas Discharge Tube Arresters (GDT)

A gas discharge tube (GDT) is an electrical protection device that is designed to be installed in an electrical system to protect both the system and the equipment it connects to from dangerous levels of voltage. GDTs are also used in the generation and transmission of electric power.A CG2420L is a type of GDT designed to protect against overvoltages in low-power AC power applications. As one of the most popular GDTs on the market, it features an all-ceramic enclosure, is self-extinguishing, and is flame-proof rated UL 94V-O.The CG2420L has a unique design which makes it ideal for applications where space is limited. It consists of a carbon coated anode, a zirconium dioxide cathode, and a gas mixture of sulfur hexafluoride, air and nitrogen which is sealed inside the GDT.The working principle of the CG2420L is simple. When an overvoltage surge is detected, it triggers a process in which electrons are stripped from the gas mixture and passed between the carbon anode and the zirconium dioxide cathode, forming an arc. This arc is the “discharge” which is designed to limit the voltage of the surge and thus protect the system.The CG2420L is an ideal choice for applications such as solar power systems, telecommunications systems, power-over-ethernet installations, LED lighting, and industrial process control. Its easy installation, reasonable price, and reliable performance make it a popular choice for many applications.The CG2420L also offers excellent protection against overvoltage events such as lightning strikes, power surges, and brownouts. This makes it an ideal choice for power plants, manufacturing plants, and other industrial facilities which need reliable protection from overvoltage events.In conclusion, the CG2420L is a great choice for applications which require protection from high voltage. It is easy to install, affordable, and offers excellent protection for systems and equipment. As one of the most popular GDTs available, it is sure to meet the needs of many applications.
