Gas Discharge Tube Arresters (GDT) are an important class of overvoltage protection devices, which are commonly used in power systems to reduce the potential fire, equipment damage, and power supply disruption. 2027-40-CLF arresters are high-performance GDTs, designed for use in medium voltage applications. This article discusses the application fields and working principles of 2027-40-CLF arresters.

The 2027-40-CLF arrester is suitable for AC power systems with voltages ranging from 1kV-15kV. The device is used in outdoor environments and features a patented gas filling process, which provides increased safety, long service life, and excellent overvoltage protection performance. The arrester is designed to deflect surge currents ranging from 1kV to 15kV. In addition, the 2027-40-CLF arrester is designed to resist lightning surges of up to 25kV.

The working principle of a GDT arrester is based on electrostatic shield and gas discharge technology. When a surge or overvoltage occurs, electrons are attracted to the sparking gap – a region of reduced electric field intensity between the tip and the shield. The electrons are discharged in the form of a spark, which helps to reduce the voltage, and dissipate the surge current.

The 2027-40-CLF arrester is designed to provide reliable, consistent overvoltage protection. The arrester is made up of two components: the arrester core and the spark gap. The core consists of a solid metal tube filled with a gas mixture. The mixture helps to reduce the electric field intensity between the tip and the shield, thus preventing sparking. The spark gap serves as an additional protective barrier that helps to reduce the voltage and dissipate the surge current before it reaches the core.

The 2027-40-CLF arrester also features a patented gas-filled spark gap, which helps to reduce the lightning current peak by more than 50%. In addition, the device is able to provide a low rate of discharge and low leakage current throughout its service life. Furthermore, the 2027-40-CLF arrester is resistant to humidity and moisture, making it suitable for installation in moist and outdoor environments.

The 2027-40-CLF arrester is an effective device for providing reliable overvoltage protection to medium voltage power systems. The device is designed to resist surges of up to 25kV, and its gas-filled spark gap reduces the lightning current peak by more than 50%. In addition, the device is capable of providing a low rate of discharge and low leakage current throughout its service life. The 2027-40-CLF arrester is suitable for installation in outdoor environments and can provide reliable protection against voltage and surge events.
