Gas Discharge Tube Arresters (GDT) are an important protection device in the power supply system. In recent years, 2027-60-B has become a popular GDT. It is widely applied in power distribution and communication system due to its advantages in double protection scheme. Here the working principle and application field of 2027-60-B will be introduced.

Working Principle

2027-60-B is a typical GDT that uses a high-pressure gas in a sealed container to absorb overvoltage and protect equipment from damage. It contains a sealed metal cylinder that is filled with a gas mixture, usually air or nitrogen, at a pressure higher than atmospheric pressure. The pressurized gas has replaceable electrodes, also known as cores. The core is connected with an external voltage supply and a surge diverter. When an overvoltage occurs, it is conducted to the electrodes, and the resulting electrical stress ionizes the gas in the tube, causing a spark to traverse the gap between the electrodes. This spark counteracts the original overvoltage and surge current.

Application Field

2027-60-B GDTs can be used in many different types of systems, such as power distribution systems, communication systems, embedded systems, and even as a surge protection device in automobiles. They are especially well-suited for protecting communication systems. In particular, they perform well in protecting data and analog signals, such as telephone lines, fax lines, and other low voltage systems. The 2027-60-B also has a low response time, making it an ideal solution for lightning protection for even the most sensitive of electronic components. In addition, it offers a reliable protective solution for large-scale installations in power distribution systems, such as substations, airports, and military bases.

Conclusion

2027-60-B is a widely applied GDT in power distribution and communication system due to its efficient double protection scheme. It provides reliable protection by absorbing overvoltage and surge current. In addition, its low response time makes it ideal for protecting sensitive electronic components. Thus, it is a great device to have in power distribution and communication systems.
