Gas Discharge Tube Arresters (GDT) are an essential piece of equipment used to protect electrical equipment from the dangers of lightning and power grid-caused surges. CG5230LTR is a type of GDT, and it is designed to protect communications equipment, data cabling, and other sensitive electronic equipment. In this article, we will discuss the application field and working principle of CG5230LTR.

CG5230LTR are high-voltage protected lightning protection device, which is mainly used in the lightning protection of communications and data line, equipment, consumer electronics, digital TV, optical fiber cable, wireless network, WiFi, mobile phone base station and other outdoor communication systems, and also used for the urban power system. The typical application fields include long-distance communication, microwave communication, mobile communication, mobile phone, radio and television broadcasting, etc. CG5230LTR also has a wide range of application in the military field.

When lightning strikes in the protected area, the ultra-high energy generated by the lightning will flow to the grounding wire to form a lightning protect circuit. In order to protect the equipment in the protected area from damage, a CG5230LTR GDT will be installed between the protected area and the ground wire. The working principle is that when the lightning current flows in, the GDT will quickly trigger the surge voltage to ionize the gas inside, and form a conduction channel, which will provide a low-impedance path for the surge current, so that the surge current can be discharged to the ground wire, thus the equipment in the protected area will not be destroyed.

The CG5230LTR has a unique design, which consists of two parts: an outer vinyl shell that acts as an insulation shell, and an inner metal shell which is the main body of the GDT. The inside of the GDT is filled with sulfur hexafluoride gas and metal electrodes, and when the surge voltage is high enough, the gas will ionize and form a conductive path, so that the surge current will flow through the GDT and be discharged to the ground wire. The CG5230LTR can provide up to 90kA of surge protection.

In addition, the CG5230LTR also has the characteristic of low residual voltage. When the surge current is discharged, the voltage across the GDT will decrease rapidly, and the voltage across the protected area will drop from a very high level to a normal level, which can effectively protect the equipment in the protected area from damage.

In summary, CG5230LTR Gas Discharge Tube Arresters are an essential piece of protection for electrical and communications equipment. Their unique design provides up to 90kA of surge current protection, and its low residual voltage ensures that the voltage across the protected area will quickly drop to a safe level after the surge current is discharged. Therefore, CG5230LTR GDTs are widely used in many applications, from telecommunications and power grid systems to military applications.
