Gas Discharge Tube Arresters (GDT) are popularly used in various industries and commercial establishments. They are especially necessary for protecting electrical devices and equipments from damage caused by high-voltage surges. CG90L is among the most widely used GDT devices and its application field and working principle will be discussed in this article. CG90L Application Field. CG90L GDT is an over-voltage protection device that is used from low-voltage electrical systems up to 5KV. As such, it is widely used in many industrial and commercial establishments, including:

• Telecommunications Equipment: CG90L GDT is an ideal choice for providing protection for telecom facilities, as it is capable of handling electrical surge caused by lightning strikes and other natural disasters. It also has a low variation between voltage and current and is very reliable over time.
• Power Supply Systems: This type of GDT is also useful in power supply systems. This is because it can ensure a stable electricity supply even when the voltage fluctuations happen. And because of its low voltage and current variation, it can minimize power losses due to electrical surge.
• Air Conditioners: CG90L GDT can also provide protection for residential air conditioners and commercial cooling systems. This is because it can withstand a wide range of voltage and current variations, ensuring that the cooling system does not get damaged or disrupted due to electrical surge.
• IOT: CG90L GDT can also be used for IOT (Internet of Things) applications, where it can provide reliable and secure data transmission and protection against cyber-attacks.

CG90L Working Principle. CG90L GDT consists of two main components: a semiconductor base plate and a conductive ceramic plate. The semiconductor base plate is a special type of carbon-graphite-based material that possesses certain electrical properties such as low electrical leakage, excellent electrical insulation and good thermal dissipation. This base plate is connected to the conductive ceramic plate, which contains small metal particles that will act as electrical conductors when energized. When the CG90L GDT is exposed to an over-voltage situation, the semiconductor material on the base plate serves to prevent electrical leakage, while the conductive ceramic plate reduces the voltage to a safe level. When an electric current is passed through the GDT, the metal particles contained within the ceramic plate will compress, creating a strong electric field, which will dissipate the excess charge. This will protect the electronic devices and equipment from any potential damage and malfunction. Conclusion. CG90L GDT is a reliable and effective device for over-voltage protection in different industrial and commercial applications. It is composed of two components: a semiconductor base plate and a conductive ceramic plate. The semiconductor material ensures electrical insulation and thermal dissipation while the conductive ceramic plate contains small metal particles that will act as electrical conductors when energized, dissipating the excess charge and protecting electronic devices from damage.
