Gas Discharge Tube Arresters (GDT)

Gas discharge tube arresters (GDT) are protective devices that are primarily used to protect electrical equipment from transient overvoltage events caused by lightening strikes, switching surges as well as internal disturbances such as arc flash. GDT features an insulation between the two electrodes to provide safety to such volatile situations. Gas discharge tube arresters (GDT) are widely used in various industries such as telecommunications, electric power, and military & aerospace applications.GTCA28-151M-R05 is a type of high energy gas discharge tube arresters (GDT). It is designed for use in applications such as lightning protection, arrester, high surge protection, surge diverter and surge suppressor. It can be used in communication signal and power system. This type of GDT has a two-layer insulation structure which provides higher impulse current withstanding capability and higher voltage breakdown than ordinary GDT. Its working voltage is above 28KV, and its operating current is 0.1KA. It also has a wide operating temperature (-40°C -- 80°C), which make it more flexible.The working principle of GTCA28-151M-R05 is quite simple. It consists of two electrodes. When there is a voltage across the electrodes, the two electrodes can form an electric arc. "The arcing current passes through the GDT and divides a portion of the energy surges from the current flow, thereby protecting the equipment from the damaging effects of these power surges." The GDT can then recover its original shape once the energy surge dissipates. GTCA28-151M-R05 also has some other features such as good mechanical stability and low after-effects of insulation. The GDT can absorb power surges up to 151KA, ensuring that the equipment is well-protected from them. It also comes with a temperature-dependent life-Cycle and a low-profile with an adjustable arc position of 0-9mm to make sure the arrester is installed properly in the equipment.The GTCA28-151M-R05 is suitable for power line communication systems, lightning impulse current limiting, arc-pressure releases, and lightning protection devices for data communication equipment. This arrester can be used in various applications, such as single-phase systems, AC/DC surge countermeasures, industrial automation, machines and transformers, power supplies.In conclusion, GTCA28-151M-R05 is an advanced type of gas discharge tube arresters that offers high surge protection, higher voltage breakdown and a wide temperature range with low after-effects. Its two-layer insulation structure ensures that it is capable of handling high-energy surges, and its adjustable arc position makes it suitable for various applications. The GDT is designed for safety and protection of electrical equipment from various voltage transients.
