Gas discharge tube arresters (GDT) are a type of voltage-dependent, electrical protective device used in power systems to provide lightning mitigation. GDTs have been used in a variety of power system applications, including telephone and power lines, electronic and electrical components, transmission systems, and more.CG2250L is a novel type of gas discharge tube arresters (GDT) with a higher electrical resistance and lower breakdown voltage. The robust structure makes it suitable for a wide range of applications, such as for electricity/telephone poles, transformer and switchgear installations, as well as for other high-lightning risk applications.The CG2250L application field includes telecommunications, power, renewable energy, and other industries in which lightning protection is a key requirement. Its robust construction and small form factor make CG2250L suitable for use in harsh conditions and difficult to access areas.The working principle of the CG2250L gas discharge tube arresters (GDT) is based on the gas discharge phenomenon. When a surge wave of sufficient voltage and energy is applied, an ionization process is initiated in the non-conductive gas inside the tube. This ionization process causes an electric arc to form, leading to the creation of an electric delivery loop, which diverts the energy away from the protected equipment, thus providing the necessary protection.When the voltage drops below the breakdown voltage, the arc is extinguished and the GDT is ready to block the next surge event. The CG2250L has a higher arc extinction voltage than most other standard GDTs, making it more suitable for electrical power systems in lightning prone areas.The CG2250L also features a self-cleaning arcing chamber, which eliminates the need for manual maintenance after installation. This device also has an enhanced mechanical shock resistance to minimize the risk of mechanical damage during installation or testing.In conclusion, the CG2250L gas discharge tube arresters (GDT) is a reliable and versatile lightning protection device, with a high electrical resistance and low breakdown voltage that makes it suitable for a variety of applications. The robust construction and enhanced shock resistance make it ideal for electricity poles, transformer and switchgear installations, as well as for other high lightning risk applications. It also features a self-cleaning arcing chamber, eliminating the need for manual maintenance after installation.
