The gas-filled arresters are a kind of high and low voltage switchgear used to prevent surge voltage and overvoltage from damaging electrical equipment and to protect power lines. They are widely used in medium-voltage distribution systems and in lightning protection. Gas-filled Arresters are also known as Gas Discharge Tubes (GDTs).

Gas Discharge Tube Arresters (GDT) have been used in power systems for more than a century. 2027-20-C GDT has many advantages over other types of arresters. It has high insulation resistance, which is necessary for high voltage environments, is not affected by power frequency changes, is highly reliable and durable and has a self-cleaning effect that removes accumulated dust. Additionally, the 2027-20-C GDT is simple in design, making it easy to install and maintain. It also increases the safety of the power system by providing both overvoltage and spikes voltage protection.

The 2027-20-C GDT is composed of three parts: an internal electrode, an outer electrode, and an intermediate insulating layer between them. The inner electrode is divided into two sections that are isolated from each other. The outer electrode is in contact with the surrounding circuit. When a voltage is applied, it passes through the insulating layer between the electrodes, creating a potential difference. This results in a spark discharge that serves to reduce the applied voltage and protect the power system.

The 2027-20-C GDT is designed to have a lower breakdown voltage than other types of GDTs. This allows it to absorb a greater amount of energy before failing and can offer more protection against surges and overvoltage. The 2027-20-C GDT has a wide range of applications in power systems. It is used to protect both the supply lines and the users from overvoltage situations. It is especially useful for power plants, factories, hospitals, airports, and other places where high voltage disturbances are likely to occur.

In addition to overvoltage protection, the 2027-20-C GDT is also used for protecting electrical equipment from lightning strikes and to reduce the risk of power outages. It is also used to prevent voltage spikes, which can destroy delicate electronic components. By effectively absorbing high electric currents, GDTs help to prevent destructive power surges from passing through the system.

The 2027-20-C GDT can be used in environments with a wide range of temperatures due to its outstanding insulation properties. It also has a strong dielectric strength, which can handle up to 6 kV, making it suitable for medium voltage applications. The GDT is designed for use in both indoor and outdoor applications. Thanks to its simple design and durable construction, it is particularly suitable for residential, commercial, and industrial applications.

The 2027-20-C GDT is a reliable and economical way to protect power systems and equipment against high voltage surges and overvoltage events. Its high insulation resistance, strong dielectric strength, and self-cleaning effect make it an ideal choice for a variety of applications. With a simple design and excellent performance, the 2027-20-C GDT is an excellent choice for protecting power systems and electric equipment.
