Gas discharge tube (GDT) arrestor, or surge arrester, is a very important part of an electrical system. Its purpose is to protect electrical equipment from the damage caused by lightning strikes and switching surges. CG90LTR is a type of polymeric low-voltage arrester, that effectively limits transient overvoltage. In this article, the application field and working principle of CG90LTR will be discussed in detail.

GDTs provide reliable, economic and optimum protection against lightning overvoltage. GDT arresters are available with different thresholds of operation in order to meet different requirements. CG90LTR is a non-linear, protective arrester that operates at a very low voltage. It is installed in series with other protection devices in order to protect electrical equipment from the high voltages created by lightning strikes and switching surges. The CG90LTR arrester is suitable for protection of a variety of electrical systems, including industrial, commercial and residential installations.

The working principle of a GDT arrester can be divided into two parts: electrical breakdown and recovery. When an overvoltage conditions occur, the CG90LTR arrester will cause an electrical breakdown and disconnect the line from the power source; this is done to prevent the overvoltage from entering the electrical equipment. After the overvoltage is over, the arrester will thenspring back to its normal position and reconnect the line to the power source. This process, which is called recovery, ensures that the power supply is not interrupted during the overvoltage period.

As mentioned above, CG90LTR is a type of polymeric low-voltage arrester. It offers a long service life and excellent protection against transient overvoltages. The device also has a very low blocking voltage, which makes it ideal for preventing transient overvoltages from entering the system. CG90LTR is also designed to be highly reliable, has a high dielectric strength and can withstand high temperatures.

The CG90LTR arrester can also be used in a variety of applications, ranging from industrial to residential. It is suitable for a wide range of voltages and can be used in both indoor and outdoor locations. It is also compatible with both AC and DC power sources, making it ideal for a wide range of applications. Additionally, the CG90LTR arrester is designed to be maintenance free, has no moving parts and can be easily installed.

In conclusion, CG90LTR is a reliable and economical arrester that can provide effective protection against transient overvoltage. It offers a long service life and is suitable for both AC and DC power sources. CG90LTR is designed to be highly reliable, can withstand high temperatures, is maintenance free and can be easily installed. It is widely used in a variety of applications, ranging from industrial to residential installations.
