Gas Discharge Tube Arresters (GDT) are vital components for energy industry and high voltage circuit. Since the 20th century, GDT have been developed rapidly and been widely used in various fields of electric and communication industry, such as lightning protection, over-voltage protection and power supply. This article is mainly focus on 2036-07-C2 application field and working principle.

2036-07-C2 GDT is specially designed for high voltage and current devices. It can protect the device from the over current caused by lightning strikes, high voltage impulse and direct current faults. By limiting the amplitude and duration of high voltage, the over-voltage will be averted and the machine\'s lifespan extended. It is applied to railways, electric railways, tunnels, bridges, substations, and decks. In the transmission and distribution system of the power and communication industry, 2036-07-C2 GDT can also be used as a protective device for transmission lines.

The 2036-07-C2 GDT is a self-healing, non-linear protective device. It is composed of a core, three terminals and two or three ceramic shells. A voltage dependent ceramic dielectric fills the gap between the cores. When a high voltage is applied, the dielectric breakdown occurs, leading to an arc which forms between the two electrodes, thus the current is discharged. This will limit the voltage applied across the GDT, and protect the protected equipment. After discharge, the dielectric will self-heal and the GDT restored. The GDT will reach its functioning state after 1 or 2 voltage cycles.

In conclusion, 2036-07-C2 GDT is designed for high voltage and current devices. It is applied as a protective device for transmission lines in the power and communication industry. It is composed of a core, three terminals and two or three ceramic shells. When a high voltage is applied, the dielectric breakdown occurs, the current is discharged, the voltage is limited, and the equipment is protected. After discharge, the dielectric self-heals, and the GDT is restored.
